What type of baluns should I use and what wires go where? What would it do by pressing that button a lot?

What button is that? no image showing. I haven't got a spare camera to try. If anyone knows where I could get a balun like this let me know:- http://adata.co.uk/ttp111vpd

This is what I am seeing

Its a dark grey screen with date/time in the corner.

Moved the power supply to directly beside the ptz camera but made no difference still black screen. Any other suggestions? If its a stuck iris how can this be resolved?

Should I upgrade the power supply to 12v 5amp? Thanks

Hi, Thanks for the information. I was wondering if the power supply I am using at the camera is sufficient (output 12v 3000mA):- http://www.ukcctvsystems.co.uk/qvis-mini-ptz-mini-ptz-dome-12x-without-wdr-500tvl The camera in the yard is about 50 feet from the power supply for the camera which is also in the yard. The house is about 150 feet from the camera. Thanks

So I have a cctv set up which has a ptz camera for use around the yard, it has a power supply in a shed outside, the cat5 cable is then underground to the house where it is plugged through a balun into a dvr, the system has worked for 2 or 3 years but went to use it the other day and everything works apart from there is no image. I can turn the camera using my phone and laptop and the date/time is in the top right hand corner of the screen although the rest of the screen is just shown as a dark grey. What could be the problem?
