G'day Guys
This is my first post, just discovered the site...very imformative
I did a 5 analogue infared camera install in to a car service garage workshop 6 months ago.
It is over cat5, using seperate cables for each camera, the longest 90 metres.
I keep losing video on the cameras.
I have changed the Blauns (both ends), I have used a combined 4 channel unit which supplies power and video on 4 of them, changed cameras, changed power supplies, cut off the cat5 plugs, re-pluged using a different brand.
I seem to have them all running ,then one fails, sometimes I just unplug the camera from the blaun (DVR end) and re-plug and it comes alive, other times turning the power supply on/off works.
It's not always the same camera.
I'm about to now put in a central power supply unit, thinking maybe the power is not enough.
I have done 12+ installations in the past no problems.
There is a lot of power running through the building, close (12") to my cameras and cat5 cables, 3 pahse, electric car charging cables etc.
The camera's 1-4 are the same camera 5 is different, they are numbered 1 closest - 5 farest camera 3 & 4 had waving lines occasionally, I fitted suppresors and the fixed that problem.
Does anybody have an idea what I have done wrong?
Thanks
Mark
