I'm looking for two option's, a low cost,low quality system & a quality,competive price system. domes w/ 420Tvl to 500+TVL, in bullet style fom 500+TVL. DVR's would usually be 500gb upwards.

This is more towards the Irish & english guy's, but where is the best place to buy gear? I get my gear from a few different supplier's in Cork & Dublin but trying to balance quality & what the client will actually pay are 2 different thing's. The margin's are tight and the only way I can make some money is by reducing cost. Thanks. Dan

My 3 recent installs, distances of 10mtrs to 70mtrs, have gone horribly wrong. I used Cat5E for the 1st time and probably last! I could not get the power up. When i put power directly to the camera and used the cat5e for the video signal it worked fine. It happened on about 11 out of 16 cameras. I re-ran some of the cable and some of them just seemed to fix themselves. Really strange. I have a big job next week & I don't know should I risk the cat5 or go with the RG59?

Agreed, long distance transmission has nothing to do with the OPs question, but you tossed in a common misconception regarding the Tesla vs Edison debate, and I wanted to correct the record. Regarding the OPs question, increasing the voltage could help because that decreases the current for the same power, and 24VAC is a reasonable suggestion. However, I would still like to know the answers to the questions I posted before making any recommendations. For example, I'd like to know more about the connections (e.g. RJ45 or screw terminals). Best, Christopher It was bulk cable cut to length from my normal supplier. All the runs were in duct so no chance of damage to cable. I used baluns on each end. DC power supply. The cameras were from ICRealtime. I think the problem may be the dc/ac supply. Sound for all the replies. Rgrds, Dan
