Elro ( Byron ) Problems

[Builder1]

--------------------------------------------------------------------------------

Hi guys, i'm new on the forum and I'm after some advice please.I currently have a ELRO(Byron ?) Unit with 4 X Channel.The first problem that i have is in quad mode the dvr runs perfect but if i put it in auto after 5 mins.coloured lines flash across the tv and the camaras freeze, if i take out 1 camara no matter which one it works fine any advise please. 2. if i can't get over this problem i would like to change the dvr and keep the cameras,The cables from the cameras are (s-video with round 6 pin mini-din ends) they run through walls, floors etc etc so would be a pain to replace.My question, is there anyone who can recommend a way to replace the mini-din's with bnc connectors and power so that i have a choice of dvr's, I have tried Maplins and a few more places with no results, All help is greatly appreciated.

First of all it sounds like a power supply issue. (PSU)
Trouble is these run from the DVR IIRC.
You could keep the cams and use a new PSU and DVR. Cutting off the DIN plugs and using BnC and standard power connections.

Or cut off the dins and remake connections with a new 4amp PSU amd BNC`s. This way you only have to buy a few connectors and a PSU.
But be warned if one part has failed another might as well.

All you need to do is identify the power and video feeds, not difficult with a multimeter.
You may find a schematic on their site
