Why the color become light or video image not stable, even no video image after connecting DVR, but the video image is good while into monitor directly?
Video signal would be degradation once through any cable transmission, either coaxial or twisted pair wire. Especially the video signal through DVR (analog to digital signal) that signal loss would be bigger. If the video signal output less than 0.8Vpp, the picture display would lack quality and have bad or ghost video image. You could use our following products for improvement. 1. For Coaxial cabling, you could add our video amplifier CA101/CA101A/CA404/CA101VH etc at the front of DVR. To boost the video signal. 2. For twisted pair cabling, you could alternate the passive receiver to active type TTA111VR/,TTA111AVR/TTA414VR/TPA008/TPA016, which built in brightness and sharpness controls If range over 1.5Km, you could add one more sets active video transmitter/receiver for series connection.
