Why is the video image unstable and color abnormally light (sometimes even resulting in no video image) when connecting to the DVR, but the video image is good when connected to the monitor directly?
Video signals will degrade once transmitted through any cable, be it coaxial or twisted pair wire. Video signals through DVR (analog to digital signal) experience an even more severe signal loss. If the video signal output is less than 0.8Vpp, the picture display will lack quality and have bad or ghosted video images. You could use our following products for improvement: for twisted pair cabling, you could alternate the passive receiver to active type VBA100R/VBA400R/VBA800R-1U/VBA1600R-1U, with built-in brightness and sharpness controls. If the range is over 1.5km, you could add one more active video transmitter for series connection.
