tampertwo Posted August 15, 2007 Posted August 15, 2007 If cam works ok on another channel and the channel in question is ok with a different camera then swap channels, Not an answer to the whiting out but solves your problem, poss low sync from camera.
chalky Posted August 15, 2007 Posted August 15, 2007 what type of lense is on the camera dc or auto if its auto you could try adjusting the levels on the lens. TVX systems what a good idea by the time the picture had downloaded the intruder would have been long gone.SFE.Solutions security systems

Russell Posted August 15, 2007 Author Posted August 15, 2007 The cameras fine on another DVR yeah the camera is fine on another dvr. it is a dc lens. I do think it could be a voltage thing, have had similar stuff in the past. but just used to unplug and reset connections. didn't work this time. the channel is terminated. will have a look again tomorrow at the terminal but really appreciate the ideas, please let me know if you have any more ideas.
Russell Posted August 16, 2007 Author Posted August 16, 2007 I've never had to do it before (maybe I've always been lucky) but do you think i should adjust the impendence levels on the dvr?
arfur mo Posted August 16, 2007 Posted August 16, 2007 I've never had to do it before (maybe I've always been lucky) but do you think i should adjust the impendence levels on the dvr? impedance is the termination needed for the camera, if not passing through to another device (as said earlier) like monitor or composite to UHF converter then it should be set to 75 ohms. acid test is plug one of the working cameras into this 'problem' input. if it works and the problem camera works in another input leave them swapped over. regs alan If you think education is difficult, try being stupid!!!!
