Try upgrading your power supply........Depends on cable length, amount of IR . Don't be too quick to condemn your video connection. I have had occasions where the supplied power supply 500 mah is too little for the camera to operate. Try using a 1amp power supply and see if that cures the problem.

it could also be a ground loop problem, try using a ground loop isolator on the camera input, if the camera is on a different phase to the recorder this also could cause problems, the isolators are commonly known as humbugs.

ps does anybody have any information on an ultrak kd6 dome, having problems with the telemetry on the unit

There are actually a lot of fraud CCTV cameras wherein they sell it off inexpensively, duping their customers into thinking that they were able to score a bargain but in reality these are just cheap imitations and do not really function that well.

At least, try use standard video output using line-level RCA type cables or put away other appliencies such as refrigerator motor, heater elements etc.

Try plugging a test monitor in at the camera end and see if they dissapear.... If they do then you know you are picking things up along your cable run, if you dont then it could be the camera's. hope this helps

A few other things that might be causing an issue for you:
1) If your cable is unshielded, you could be picking up EM interference on the line.
2) If your power supply/power supply line is not dedicated tot he camera, for example its split with another device like a housing heater/blower, you can get this too.
3) I've seen this happen even WITH shielded cable, but where the cable is run too close to things like florescent lighting.

Hope this helps.
