hi i got a camera in ebay. it states 700tvl 1/3dis sensor . it records @720x576 pixels.(am using a usb video grabber) how to find out whether its 700tvl or not.

A sunnykim, thanks for the reply

hi , i have a 700tvl 1/3" DIS camera via utp cat5 and passive baluns(25feet) . power source 12v dc 1amp. connected directly to a monitor for realtime montoring. i get video signal losses every now and then. once signal lost , i have to disconnect and reconnect my BNC rca adapter from the monitor. some times the video loss is during the night and day vision changing.(i mean IR ON/OFF). some times even during voltage fluctuations. IS this a ground loop problem? help pls.... i have attached a sample video of the problem 4MCLtCte37E

i replaced the rca adapter but of no use still.. the problem continues.. have asked the dealer to check the camera

Hi, I use 3 pairs for power and 1 pair for video (cat 5). i'll replace the bnc rca adaptor and see.. thanks 4 ur reply

But the camera is on even during the signal losses... if voltage not enough the camera should turn off no??
