  1. 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

    Installation Problem In Service Garage

    Soundy When you say shared powered supply, do you mean a regulated standalone supply split to different cameras or a dedicated supply like this: http://www.ddstrade.co.uk/12vdc-central-distribution-power-supplies.html Would this be a better option for powering multiple cameras from one location in the future?

    Installation Problem In Service Garage

    Thanks Soundy, I will try it on 3 twisted pair, so I do not have to buy new blauns I will put on new cat plugs at the camera end using just the video pair, then splice off 3 pairs and attach a power plug. As a future idea could I put 24vac up a cat5, then put a 24vac>12dc converter on the camera end? Thanks Mark

    G'day Soundy The cameras draw 2.5 watts each. As far as I can tell one pair. Thanks for a fast response Mark
