  • Should I use a wireless camera for my application?

    Wifi signals, especially at long distances, can drop or become unreliable. They also become targets of hacking "resulting in free access to your personal cameras (EXTREMLY DANGEROUS) or blocked cameras, ones that will not record anything." It is best to use a hardwired connection via cable for installations. PoE installation can supply signal and power over one cable for easy installation. If a cable is not an option consider using a dedicated wifi access point, like the type made by Ubiquiti Networks.

  • Network Camera PoE is not powering up, but DC adapter can, how to solve this issue?

    Regarding the technical problem you mentioned, the IP camera is only work with the DC12V adapter, therefore, I have summarize the possible causes as below for your reference:
    1. IP camera PoE: Is the IP camera PoE functional before? 
    2. LAN cable connector: Please exchange the LAN cable with other one which is in working order with other IP camera.
    3. PoE hub of LAN port: Please reconnect the PoE hub of LAN port and try again.
    4. 26 pin FFC cable: Please check the 26 pin FFC cable (the white color one, which connects the PoE board and the DSP board) and confirm if the FFC transmission signals has any loss or not.

  • Will the PRX-400PVD receive video signals from direct connection to control and recording equipment?

    The PRX-400PVD has a 4-channel passive receiver hub built-in. This feature is equivalent to the PTT-1600V passive receiver hub and means that when connected to an I-View’s PVD passive transceiver, video signals can be received at distances up to 300m. This means that UTP video signals can be received and be directly connected via coax BNC output to a DVR or IP video servers.

  • How is the PRX-400PVD different from the PoE (Power over Ethernet) device?

    PoE devices are designed to power IP network devices such as IP cameras. 

    Although the PRX-400PVD follows the same EIA/TIA 568B structured building wiring and pin outs, it delivers 24/28VAC while PoE supplies 48VDC power. 

    The PRX-400PVD is designed to power conventional analog cameras and pass analog video and control signals.

  • Will this unit deliver enough power for Fixed and PTZ cameras?

    With up to DC12V/1.5A Amp per channel, (AC28V/3.57A or AC24V/4.17A aggregate) the PRX-400PVD has the power to drive almost any indoor CCTV network.

    In general, cameras with outdoor heaters and blowers draw more than 1 Amp, which exceed the rating on RJ45 contacts. Each channel can be switched to 28VAC, allowing extended cable distances when needed. It is important to follow our calculator http://www.i-view.com.tw/support/calculate_cable.htm for power at distance to ensure a system performs to specification.

  • How do I position the PRX-400PVD with customers?

    First, the customer needs to understand the I-View PVD solution and its benefits.

    The PRX-400PVD Solution is a key component in the PVD system and is not well positioned on a standalone basis.

    Once the customer has agreed to a structured cabling based CCTV network and is on-board with the benefits of analog cameras and transmission via PVD, the PRX-400PVD will add significant value in simplifying the installation.

  • How does the PS2804-AC power supply product features different from a traditional rack mount CCTV power supply?

    I-View has loaded best-in-class features as below:
    a. Support AC28V/3.57A or AC24V/4.17A (Selectable).
    b. Using by Toroidal power transformer to get better power efficiency.
    c. Build in Surge protector and AC power noise filter.
    d. Build in PPTC resettable fuse for short and current overload protection.
    e. Diagnostic LEDs show load/no load, short-circuits and overload conditions.
     f. Support 1U high of 19” rack mount installation.

  • Which models can work with the PS2804-AC?

    The PS2804-AC is an AC power supply and it can work with PRX-400PVD and PRX-120VP.

    Combine the PS-2804-AC and PRX-400PVD (Or PRX-120VP) as a power supply, passive video receiver and pass-through video & telemetry data cable integration device for up to 4 (1) cameras, each via a single RJ45 4-pair UTP cable.

  • How many functional dome cameras can I power from the PS2804-AC?

    The PS2804-AC provides up to 8 ports AC output and the power supports AC28V/3.57A or AC24V/4.17A total aggregate. So it can support about 8 pcs DC12V/600mA dome cameras or 4 pcs DC12V/1A functional PTZ dome cameras.

  • How far can I power cameras from the I-View's PVD?

    1.  The PTX-120VP can provide DC12V/600mA up to 300 meters transmission distance.
    2.  The PTX-100PVD can provide DC12V/1.5mA up to 300 meters transmission distance.

  • Can I choose any type of CCTV camera with PVD?

    The PVD has been designed for internal low voltage static & fully functional cameras without a heater or blower, not exceeding 1Amp.

  • Will RF interfere with the video signal when using EZLink CCTV transmission device?

    No, EZLink device is highly immune from teh interference.

    Cat 5 UTP wire is immune from RF interference. But the high power (signal noise ratio) RF signal would occur the video interference, neither coaxial nor UTP/STP cable transmission. There're three solutions to solve this problem:

    A) When using the coaxial cable:

    Using our CS-700RS RF modulator to avoid this problem. I-View's RF modulator allows work with high voltage cable at a time.
    B) When using the UTP cable:

    Most of the I-View's UTP devices could provide a higher immune to interference. That is, the equipment is only concerned with the voltage difference between the two conductors. RF or other fields’ will still couple into the conductors, but will do so in each conductor equally. This Common-Mode signal is ignored by the I-View equipment, which has a 60 dB Common-Mode Rejection Ratio (CMRR).

  • How to protect the CCTV equipment being destroyed from the high voltage surges when there's lightning strikes in nearby?

    Using I-View’s EZLink CCTV transmission products.  

    All EZLink products have inserted a surge protector (Except PTT-100V, PTT-120V, PTT-100VP, PTT-400V and PTT-1600V).

    We'll put surge protectoer on both camera and DVR equipment.

  • Why does my video look like a scrambled Cable TV signal?

    This is commonly happend when polarity reversed.

  • Why does the video sometimes appear foggy signals like too bright, snowy or even wavy when using the I-View Active Balun products?

    Please adjust the two conditions as below:
    1. The Active Balun products are designed for long-distance transmission, the product has built-in a video distribution amplifier which will adjusts the amplitude of a video signal and extend the distance of the video signal transmission. Therefore, if your transmission distance is under 300 meters, the video distribution amplifier function would be too strong to occur snowy, wavy or even bright imagesPlease change the device from Active Balun to Passive Balun (such as PTT-120V, PTT-130V, PTT-130S, PTT-400V or PTT-1600V) with the distance at least over 300 meters.

    2. The Active Balun has “Multi distance switch" for different distance transmission. Please switch to appropriate distance range upon your application in order to avoid fog signals.

  • Why is there a double image in my video?

    Faint shadows of the original signal shifting to the right, or “Ghosting” occurs when there is an impedance mismatch along the wire. Verify that the monitor is terminated with 75Ω (not in loop-through). Check for and remove any bridge-taps (another wire pair connected to the wire run).

  • Why there is no video image after connecting DVR, but the video is good while into monitor directly?

    The video signal through DVR that the loss would be higher, the normal video decoder of DVR requests the input 
    video signal must higher than 0.8Vp-p.  You could use our following products for improvement.
    1. Coaxial cabling: You can use our Video Enhancer AMP-100V or AMP-400V at the front of DVR.
    2. UTP cabling:  Please alternate the Passive Balun to Active type receiver ARX-100V or ARX-400V, which built in 
    brightness and sharpness controls. If the transmission range is over 1Km, you could add one more Active video 
    transmitter for long distance transmission.

  • When transmitting video between passive video Balun, the video is wavy and there is a dark bar that rolls upward on the monitor. Why?

    This is the result of a ground loop. Use an amplified receiver (which has built-in ground lifting), or remove the 
    ground at the camera end. Be sure that floating the camera conforms to local/regional and National Electrical Codes.

  • Why choose the mini passive balun device?

    The reasons are as below:
    1. I-View provides compact Video Balun, which can plug into the camera and DVR directly.
    2. No need for external coaxial jumper cable. (You could save cost!)
    3. Reduce the problems, which cause the cabling.
    4. The tool is less design and easily to maintain.

  • Are EZLink CCTV transceivers support racks mountable?

    Yes. The RMP-219 rack panel can hold up to two 4-channel transceivers. I-View's Multichannel hubs are also 
    rack-mountable and include the necessary hardware.

  • Can EZLink transmit RS-422 or RS-485 signals?

    Ther RS-422 or RS-485 signals are hard-wired between the P/T/Z equipment and are not transmitted or received 
    by EZLink transceivers. The data signal may be sent on a wire pair within the same bundle as the video signal.

  • Can I transmit satellite or cable TV using EZLink product series?

    Yes, EZLink product series provide the device, which supports the wide bandwidth cable TV signal.

  • Do EZLink product series can support broadband RF/VHF/UHF?

    Yes, EZLink product series provide the device, which uses the demodulators and modulators to convert to base 
    band composite video.

  • Can I use spare pairs in an existing telephone system to transmit video using UTP CCTV devices?

    Yes. UTP CCTV is that the wiring for video can reside along with telephone system wiring. However, please be sure as blow:
    1. To use “dry copper” pairs.
    2. There should be no dial-tone, 48 volts, loading coils, bridge-taps or switching on the chosen pairs.

  • Can Category 5e or 6 UTP wire be used?

    Yes. Our Balun device can be used with Category 2 or better UTP cable.

  • Can video signals be sent in opposite directions within the same wire bundle?

    Please follow the process as below:
    1. When using Category 2 or 3 wire, do not send video in opposite directions within the same wire bundle more 
       than 1000 inches.
    2. With Category 5, do not send bi-directional video more than 2000 inches’.

  • Can I transmit more than one video signal in a Multi-pairs wire bundle?

    Yes. The video signals can reside in the same wire bundle as multiple video signals, ringing telephones, 
    Ethernet, DC12V, RS-422/RS-485, etc.

  • Can the wire path have splices?

    Yes. We recommend designing CCTV systems in much the same way as phone/data systems are designed. You 
    can splice the wire or use 66-blocks or 110-blocks to make connections. Video can be sent through a dozen of 
    these connections without significant degradation.

  • Can Shielded Twisted Pair cable be used?

    We do not recommend using the Shielded Twisted Pair cable.  The reason as below:
    1. The Shielded Twisted Pair cable has high frequency roll-off will severely degrade the transmission distance performance.
    2. It will compensate for some signal loss when using an amplified receiver.
    But the Multi-pairs wires (More than six pairs) can have an overall shield without degradation.

  • What kind of wire should I use for UTP CCTV devices?

    Use UTP (Unshielded Twisted Pair), Category 2 or better, 16-24AWG, stranded or solid. Using a multi-pair wire (six pairs or more) with an overall shield is OK.

  • Black Picture : No Modulation

    In this case, the TV and the modulator are "talking" to each other. The video signal is not being passed through 
    the system.
    1.    Verify good connections to the modulator from the video source. i.e. VCR.
    2.    Check video source (VCR, Sat Receiver etc.) by running the outputs directly into the video inputs on the TV. Verify 
            video source is working.
    3.    Check for power at video source.
    4.    Disconnect modulator from system: A) Picture goes to snow, problem is between video source and inputs on 
            the modulator. B) Picture stays black, hook up the modulator directly to a TV eliminating all the components of 
            the system and check the picture.

  • Snowy Picture : No Modulation

    This is a problem of the TV and the modulator not "talking" to each other.
    1.    Verify the modulator is set up for the proper TV channel band. If the unit uses dip switches to set the channel 
            band, was the unit powered down during or after the switches were reset to the proper band? 
            If the unit uses a jumper check for proper placement.
    2.    Verify the TV is set up on the proper TV channel band. Use "Air" for UHF channels of Cable for Ultraband channels . 
            The TV will have an on screen set-up menu or a switch for this function. Also make sure the 
            modulated channel isn't blocked out by auto-programming. To check for the TV being set to the wrong band, go 
            to the equivalent channel on the other band (i.e. to check 65 cable try 14 UHF).
    3.    Check TV manual to make sure TV works on channels above 65.
    4.    Check all connections for a good connection.
    5.    Check splitters and amplifiers for 1GHz rating.

  • Grainy Local Channels : Good Modulated Picture

    Disconnect the modulator from the system and connect the local channel feed directly to the distribution system 
    and check TV picture quality. If the picture quality is good the insertion loss of the combiner for the modulator is 
    degrading the local channel signal. Use a CVT-15PIA to compensate for the insertion loss. The other alternative 
    is to use a 9dB tap as the combiner, put the local channel feed on the pass through port for a minimal loss of 
    signal connect the modulator to the tap off port. If the picture is still bad, check for a bad connection where 
    leakage may occur or if the shielding braid is touching the center conductor.

  • Grainy Modulated Channel : Good Picture on the Cable Channels

    1.    Disconnect cable channels from the system and check the modulated channels. If the modulated channels are 
            good, use a low pass filter to "clean-up" the incoming frequencies to be modulated. If the modulated channel 
            does not improve after disconnecting the local channels, evaluate signal loss of modulator through the 
            splitters and cable length of the system. Amplify after the combiner if needed. Also check the connections 
            between modulator and the combiner for leakage or braid touching the center conductor.
    2.    Make sure the attenuator is turned to 0.
    3.    Check output strength with field strength meter.
    4.    Connect modulator directly to TV and check picture quality.
    5.    Check band width of all splitters and amplifiers for 1GHz capability.
    6.    Place TV cable setting on standard, NOT HRC or IRC.

  • TV won't tune high enough to get modulated channel

    1.    Use an external tuner i.e. VCR or a Cable Box converter tuner (#1172) to allow the TV to view modulated channel on channel 3 or 4.
    2.    If the modulated channel is beyond the capabilities for that TV, the TV will not work with the system.

  • Cable Company Box Won't Pass a Modulated Signal

    1.    Connect modulator directly to TV and verify the modulator is sending a signal the TV can receive.
    2.    Use model 3101 Cable Box Combiner Kit to route the modulated signal around the cable box. See schematic pages 4 & 5.

  • Which type of camera do you recommend for Witness Pro DVR?

    There is no special camera requirement for Witness Pro DVR as long they are as either PAL or NTSC composite cameras (not both at the same time).

  • What kind of sound card and microphone is requested when using the audio recording?

    Please do not use the software sound card such as AC 97. The output level of Microphone over 2 Vp-p is strongly recommended.

  • Cable Company Uses All Available Channels

    Use a low pass filter (3102) to blockout channels 80 and above for clean modulation (won't effect channels 95-99).

  • Which PTZ camera are supported by the Witness XP and DigiCap II?

    Our current software supported PTZ cameras as below:
    1. Pelco P
    2. Pelco D
    3. Lilin (PIH)
    4. Kalatel
    5. NiceCam
    6. Fastdome
    7. NC-080AZ PTZ Receiver.

  • Virtual memory is found low after a several days of operation?

    When you run Witness Pro program, it will automatically occupy all the CPU resources. However, when you reboot the O.S., it will release the Virtual memory. Since we are using the schedule reboot function on the Witness Pro software to avoid this issue.
     

  • We have problems with camera connected to the and the picture of some cameras with Al or manual iris-lens is very bright.

    If you have found that your camera pictures are too bright, please adjust the camera setting from the Witness Pro program. If the problem still happens, please change the camera brightness level, or call the camera dealer.

  • The common problems associated with RF modulator system.

    The products of EZLink Coax CCTV transmission system use the RF modulation, the below command problem 
    maybe will happen on your CCTV system when you installation.
    1. Variable gain turned down to low to compensate for splitter loss, cable length.
    2. Multiple input modulators set on the same channel example 3 input mod channel set on 1 and 1.  The channel must be at least 1 channel apart.
    3. The receive level should exceed 5 dBmv and should not go below 5 dBmv at any frequency.
    4. The difference in dB level between the modulation is greater that 10 dB causing cross talk.
    5. Difference in ground potential between DVR ground and modulators grounded AC plug.

  • Occasionally, hard disk space is found low, even though cycle recording is set.

    When the hard disk is fully occupied, the oldest files will automatically be overwritten by small portion. From then, it is normal that the hard disk space will always be low at a certain level (Same as your setting). It will not overwrite the hard disk by large portion since we want to keep the recorded videos for as long as possible.

  • How much capacity of HDD should I have? How many partitions or drive should I have?

    Each drive should have more than 3GBytes and Strong recommend to have the partitioned up to 2 (X drive).  One device for the O.S. installation, the other for saving the video clips.
     

  • Why the Picture is Too Bright or Washed Out when use the of Coax CCTV Transceiver?

    1.    Slide impedance switch to 75 ohm position
    2.    If modulator is a CVT set top style, adjust video level adjustment potentiometer on the bottom of the chassis.
    3.    If using a camera, check positioning of the lens to be sure it's not aimed at the sun or a reflection.
    4.    Adjust camera lens - see lens manual.

  • Some parts of image screen looks blue and seriously corrupted.

    From the place where back part of DVR Camera is connected, switch the location between normal camera and abnormal camera. If the abnormal screen continues to look weird, camera is the one that causes the problem. Contact the person who installed your camera. But if the screen was switched from normal to abnormal then, contact our customer support center.

  • System will not shut down, how can I do?

    Press the Power button for 5 seconds then system will shut down.

  • What is the Transient Protection?

    The electric field density is very high at the top. That makes it a great target for lightning strikes. For the sake of discussion, let's say the voltage at the top of the pole is 50,000 volts. The bottom of the pole is at 50,000 volts too. If the pole is grounded, the top of the ground rod will be at 50,000 volts. And the bottom of the ground rod will also be at 50,000 volts. (Dirt doesn't conduct well.) If you were to sink a new ground rod 5 or 10 feet away, this rod might be at 49,000 volts. 
    Now, if a camera is powered from a low voltage source, there is no life-safety, electrical code, or UL requirement that it be grounded. (Check the camera's manual, too.) This brings us to an important choice. We can connect this camera to a source of 50,000 volts, or not. If we do ground the camera, then current will flow through our copper back to the head-end, which is at zero volts because it is grounded. If we float the camera, no current will flow. This principle is one-alarm installers know well: ground the head end; float the remote keypads - nothing gets cooked. 
    Ideally at the receive end, all CCTV equipment, including the I-View UTP camera, should be co-located and share the same building electrical ground. Having the I-View UTP Camera grounded to the telephone-company's ground rod, while the rest is connected to the building ground could allow large voltage differences to damage equipment.  Lightning protection is not an exact science. However, customers who have experienced problem installations have successfully employed these practices with excellent results.

  • Miscellaneous precautions when installing your system.

    1.. Make sure that the Capture Board driver is correctly installed.  Please check out the driver from: Control Panel>>System>>Device Manager>>Sound, video, game control.
    2.  Make sure to choose the correct NTSC, PAL when installing your program.  Check the cables connection on the capture board. 5. Check the connection on the cameras.
    3. Make sure the camera functions properly.
    4. When possible, avoid using software that resides in the RAM. Especially, vaccines can be potential problems.
    5. Turn off screen savers when using the program, follow up the path as Control Panel >> Display >> Screen saver.
    6. Turn off energy savers when using the program, follow up the path as Control Panel >> Display >> Power.

    5.    Check all connectors for 75 ohm.

  • Should I choose the Shielded or Un-shielded Wire?

    It is interesting to note that the EIA spec for RS-422/485 does not require shielded wire. When one reads the datasheets for RS-422/485 driver/receiver ICs, they don't require shielded wire either. Most telemetry cameras send data at the glacial speed of 4800 baud, but even if the data rate were higher, UTP wire has less loss than shielded wire. So why do some manufacturers continue to spec it? There are several possible reasons: 
    Their engineers aren't very experienced with transmission. All they know is that they want to protect their precious data, and shielded wire will have lower interference. This is partially true. Yes, shielded wire will sustain less cross talk, but the interference is down in the mill volts and the RS-422/485 signal is 8 volts peak-to-peak. A few mill volts won't affect such a large signal. What is bad is when a field engineer grounds the drain lead at both ends and large currents flow. The magnetic coupling in this case can be significant. 
    The equipment has a processor and there's a lot of stray clock-noise inside their box. The engineers don't know how to make their equipment pass the radiated emissions "smog-test", but if they use shielded wire it acts as a distributed filter. There are several ways around this:
    a)  Use three meters of shielded wire, and then convert to UTP. The emissions remaining after the three meters are negligible.
    b)  Put in a filter at the I/O connector. Place a 1000 pF capacitor from each data conductor to chassis ground. Better yet, use Metal-Oxide Varistors. These MOV devices are around 1000pF too, but they also protect against damaging transients.
    c)  Design the equipment right from the beginning.
    d)  Be a stinker. Ignore the emissions. Hey, when was the last time you heard of interference from a data line causing nearby equipment to fail?
    The equipment has a lot of sensitive CMOS that blows out when there's a lightning hit. The solutions in the previous paragraph work here; Use three meters of wire to shunt the fast rise-time energy onto the chassis, or use a filter, capacitor, or MOV.  If you're really concerned, use an off-the shelf transient protector, but connect its drain wire to the equipment chassis.  It's the way we've always done it. This is the same argument people in our industry use to continue using coax. By the way, does your Ethernet LAN still use coax? 
    Theory and specifications are no substitute for real-world operation. I-View has been shipping product for few years. There are many installations that employ UTP for their transmission of RS-422/485 data. We know of no installation that ever experienced a problem with it.

  • There is too much noise while the system is running.

    Check CPU, cooling fan of power supplier in the system. Cooling fan might make much noise as it goes on with much dust on it. You should clean up the dust on the fan and case. Aged HDD might make much noise. Aged HDD might have heat, dust, external shock, or too much saving. They will give damage to the HDD. If this damage is severe, it can make much noise or break up.

  • What is the recommended Windows picture quality for I-View software?

    I-View was all designed in a 24 bits or above environment. Setting the system to a lower quality can result in screens that are cut-off, so be sure to set your screen to 24 bits and 800x600 or 1024x768 resolution before using your software.

  • What kind Chipset of Motherboard request when I using Witness Pro system?

    The Intel Chipset is strong recommended.

  • System has stopped recording and showing disk space low.

    It possible cause for the error is corrupted database files. User should then exit the main system application and execute the repair Database Utility - "Add / remove storage device" icon from "Storage configuration" to repair the database so the recording may resume normally.

    c. Adjust camera lens - see lens manual.
     

  • Windows 98 uses the FAT32 file system, while Windows 2000/XP/Vista also supports the NTFS file system. Which file system should I use?

    Each file system has advantages and disadvantages to them.
    What are the advantages of NTFS over FAT?
    *Is journaled, decreasing data loss.
    *Allows larger volume sizes (greater than 1TB).
    *Resistant to fragmentation-Performs better on volumes ~20GB and more.
    What are the advantages of FAT over NTFS?
    *Performs faster on volumes ~10GB and less.
    *Works well with small disk cache and system cache (less than 96MB systems).
    What are the disadvantages of NTFS?
    *Suffers with small cache (less than 96MB systems).
    *Suffers with slow disks and controllers.
    *Is less space-efficient on small volumes (less than 4GB).
    What are the disadvantages of FAT?
    *Gets slower as the number of files on a partition increases.
    *Slows as volume size increases, because drive must constantly reference the file allocation table at the beginning of the volume.
    *FAT tends to highly fragment files.

  • What are the Transmission-line Effects?

    Data distribution is accomplished by paralleling the data paths to up to four cameras. Known as star wiring, this fan-out method works very well for camera implementations of RS-485 or outbound RS-422. This is because data is typically traveling at the glacial speed of 4800 baud (confirm the camera's protocol). Signals travel through twisted-pair wire at 575ft (175m) per microsecond. From transmission theory:
    1.  Propagation speed / Frequency = Wavelength
    2.  575ft/microsecond / 4800 bits / second = 120,000ft
    3.  175m / microsecond / 4800 bits / second = 37,000m
    Transmission-line effects (reflections, ringing, etc.) start at 1/4 wavelength, so divide by 4 to get 30,000ft (9,000m). Then there are harmonics of the square-edged data pulses. If we take the fifth harmonic (very conservative because edges round off at long distances), we need to divide this number by five 30,000ft / 5 = 6,000ft (1830m). This is longer than our maximum cable length, which is typically spec'd at 3,000 ft (1Km). This distance is much longer than any star-wiring-based stub because the power distribution limits us to 400ft (120m). This calculation shows that at these speeds, the system acts more like a lumped-element circuit than a transmission line. Indeed, oscilloscope measurements of the data path show clean square pulses under worst-case conditions.

  • Inserting more than one card is not supported since the current all of I-View product?

    All of I-View DVR can support more than one card up to 16 or 32 cameras input, please refer to the website: http://www.i-view.com.tw

  • What is the Interference Immunity?

    The term “balun” is short for “Balance-Unbalance”. It’s typically (but not always) a transformer where one side is connected to a signal and a ground (such as coax), and the other side has both conductors floating relative to ground, with our signal between them. For correct operation one always needs a balun at each end of the wire.

  • Why the video is black Picture?

    This is a problem of the demodulator (CRX-104PVAD or CRX-124PVD or CRX-101VAP) and the modulator (CTX-
    104PVAD, CTX-124PVAD or CTX-101VAP) are "talking" to each other. But the video signal is not being passed 
    through the system.
    a. Verify good connections to the modulator from the video source. i.e. Camera.
    b. Check video source (Camera) by running the outputs directly into the video inputs on the TV. Verify video source is working.
    c. Check for power at video source.
    d. Disconnect CTX-101VAP, CTX-124PVAD or CTX-104PVAD device from system:
    A) Picture goes to snow; problem is between video source and then inputs on the modulator.
    B) Picture stays black, hook up the CTX-101VAP, CTX-124PVAD or CTX-104PVAD device directly to a TV eliminating all 
    the components of the system and check the picture.

  • What is the Ghosts image?

    Normally a video signal travels from the source (camera) to the destination (monitor) by way of a transmission path. This path can be coax, UTP, or other media. Normally this is a single path, with no wires going un-expected places.
    Now suppose that there is an extra pair of wires (a bridge-tap) tapped into the main pair. Energy travels down the main wire pair, but it hits a fork in the road. Some of the energy continues in the right direction, but some goes down the wrong way into the bridge-tap. Energy cannot just shoot off the far end of the bridge-tap wire, so it reflects back in the direction from which it came. That energy hits the same fork, and some of that travels towards the final destination. But that energy was delayed, so it shows up at the final destination as a "ghost", a copy of the original image shifted to the right.  If one takes a ruler or tape measure and measures the right-shift, one can determine the length of the stub. This won't tell where along the main path it is.

  • Why the image of Remote software appears black after connecting to the Witness Pro DVR?

    The VG card does not install the correct or newest driver.  Please check the PC's information and update your VGA card driver from the Chipset of VGA card from the Chipset vendor’s website.

  • How to measure the Loop resistance?

    Wire distance may be measured with an ohm-meter by shorting the two conductors together at the far end, and measuring the loop-resistance out and back. Please remember to include any coax in the path.

  • Connection has failed when trying to connect to Remote access DVR (PSTN Modem case)?

    First, check to see if both of Witness Pro DVR site and Remote client PC's phone line is operation normally. Then, check the PSTN modem has been enabling on the modem function on both of DVR site and Client’s.

  • Connection window does not progress when trying to connect to remote access DVR via Internet or LAN.

    This happens when IP address from Site is not correct. In this case, DVR has to search for IP address for about 30 seconds. It does not mean that the DVR was shut down so please reconnect to the correct IP address after waiting a little while.

  • How to consider the camera power?

    CCTV cameras are available with various voltage requirements. These include 12VDC, 24VAC, and 115/230VAC. 115/230V models are rarely used, due to the expense of providing local high-voltage power. 24VAC models are quite common in that they can tolerate greater wire distances than their 12VDC counterparts, and are generally more immune to ground-loops.  A significant portion of cameras today are wide-ranging in that they can operate on 12VDC or 24VAC. 
    Should the camera operate off of 12VDC only, special considerations must be taken to ensure correct operating voltage.  These considerations include short wire runs, thick wire gauge, or slightly increasing the power supply voltage to achieve the correct voltage at the camera. Another consideration is that 12VDC cameras often connect the power supply return lead to the camera's ground. The result can be that current from the power supply may flow through the shield of the video path, a recipe for ground-loops.  For this reason, it is recommended that 12VDC cameras be powered from a local 12VDC supply that has a floating (not grounded) output. I-View has developed its UTP Camera products that allow 4-pair UTP wire to be used to deliver camera Power and Video. These UTP cameras are "cable integrator" pass-through devices that allow the use of an external power supply and RJ45 connector for in-house wiring. This allows for inter-operability with external low voltage power supplies, including those that deliver 12VDC or 24VDC or 24VAC.

  • What type of Mobile Phone can remote view the video of the Witness Pro DVR?

  • The phone cannot hear the warning voice?

    1. The telephone can accept the format of Wave file is 8000 Hz, 16 Bit, Mono only.   Please check the wave file of notification meets the request or not.
    2. Make sure your Modem can support the wave file function or not.

  • What is the Split-pai?

    If the Image looks like one video signal with a blurry copy of another image either in one place, or gliding through, then we probably have a split-pair. Video signals must be sent on a twisted-pair of wires, such as white-with-a-blue-stripe and blue-with-a-white-stripe. Do not use un-twisted wire pairs, such as blue-with-a-white-stripe and white-with-an-orange-stripe, as these signals are now coupled into conductors that may be carrying interfering signals. Two video signals wires as split-pairs will show cross talk between them and look like a ghost of the other signal on the monitor. Use caution when installing multi-pair wire that has a solid white wire and a solid blue wire, as the white wires all look the same. If you get them mixed up, do not use an ohmmeter to identify. Rather, disconnect any equipment and use a low-value capacitance meter. You will find that the paired wires have one inter-conductor capacitance value (~19 pF per foot (62 pF/m)) while the un-paired conductors have a lower value (~13pF per foot (43pF/m)).

  • Will RF interferes with the video signal when using EZLink CCTV Transmission device?

    No, EZLink device is highly immune to interference. CAT 5 UTP twisted pair wire can immunity the RF interference. 
    But the high power (signal noise ratio) RF signal would occur the video interference, neither coaxial nor twisted 
    pair cabling transmission. There three solutions to solve this problem: Using I-View multi signal coaxial 
    transmission system use the RF modulator way. It can avoid this problem. I-View's RF modulator allows working 
    with high voltage cable or high interference environment.

  • System cannot dial up to normal phone or mobile phone?

    I-View’s DVR product can support most of voice modem (external modem is strong recommended) manufacturers, whose modem uses following chipsets: Rockwell, Lucent, Conexant and IC Plus.

  • What is the Ground Loop?

    The Ground-loop. This is caused by the camera being grounded to a voltage that is different from that of the head-end. If the [low-voltage] camera is grounded try disconnecting the camera from its ground. Alternately use an active receiver, which has a differential input. If the problem remains, disconnect the UTP wires at one end and check their voltages relative to the local ground. We expect no more than about 200 mV AC. 
    Are there multiple cameras powered off the same multi-output power supply? As an experiment, try powering a camera off a separate floating supply, or use one or two gel-cell batteries (12 or 24VDC) to power the camera locally. If removing the camera from the multi-output supply solves the problem, then we may have a fault voltage coming from another camera or its wire. It's not uncommon for wire to get scraped as it passes through ends of conduit or T-bar ceilings. Check each camera one-by-one. When isolating, it may be necessary to disconnect both power conductors from the power supply.

  • How to protect CCTV equipment destroyed from high voltage surges from nearby lightning strikes?

    band composite video.
     

  • Can I use spare pairs in an existing telephone system to transmit video using UTP Cameras?

    Yes. One of the advantages of UTP camera is that the wiring for video/power can reside along with telephone system wiring. However, be sure to use “dry copper” pairs. There should be no dial-tone, 48 volts, loading coils, bridge-taps or switching on the chosen pairs.

  • Can I transmit more than one video signal in a coaxial cable?

    Yes. The multi-video signals can reside in the same coaxial cable via I-View’s CRX-400V + CTX-100V multi video 
    transmission system.

  • Can Category 6 wire be used for UTP Camera?

    Yes. Unshielded Twisted Pair wire, Category 2 or better, can be used with UTP camera.

  • Why cannot download the Active X when remote viewing the video of Witness Pro NVR/Hybrid DVR via I.E. Browser?

  • What is the stages of powering up a PoE link?

    The setup phases are as follows:

    PSE (provider) tests PD (consumer) physically using 802.3af phase class 3.

    PSE powers up PD. 
    PD sends to PSE: I'm a PD, max power = X, max power requested = X. 
    PSE sends to PD: I'm a PSE, max power allowed = X. 
    PD may now use the amount of power as specified by the PSE. 
    The rules for this power negotiation are: PD shall never request more power than physical 802.3af class 
    PD shall never draw more than max power advertised by PSE 
    PSE may deny any PD drawing more power than max allowed by PSE 
    PSE shall not reduce power allocated to PD, that is in use 
    PSE may request reduced power, via conservation mode [24]:10

  • What are the differences of RGB and YUV image signals?

    RGB signaling refers to the method of dividing an image signal to the fundamental three colors (Red, Green and Blue) when processing the signal. It has the advantage of good color division and conveyance, but the disadvantage of requiring at least 3 color (24bits) division data.
    YUV signaling refers to the method of expressing an image signal by the vertical and horizontal signal synchronization (Y), and its color signals (U, V). Color division and conveyance qualities are inferior compared to the RGB method, but the YUV method can express more diverse colors using less image data.(16bits) The choice of both methods are available on DVR. RGB images will have clearer color but more 'blocks' on the images, while with YUV images dividing between colors can be more difficult but you will get a more smoother looking surface from them.
