Hi, i have bought a ptz with ir. i have just fitted it and in daylight the picture is fine, but as soon as the ir comes on my picture goes blurred and i can not see anything, i have checked the camera and only 3 of the 11 irs are working. i did have to alter the power cable to the camera, as the adapter would have been outside, but it needed to be indoors, so i cut and joined it with some more cable using connector blocks. In the manual it states that if the image is not stable it is either low power or video cable is improperly contact. could the problem be that there is not enough power going to the camera to light up the irs, as i cut and altered the male power connectors, thanks for you help in advance, Andy

thank you dex and horizon for all your help, i have changed the power supply extention today and the IRs all work fine now, i really appreciated the help and advice you both gave me Andy

ok thanks horizon, i will find where the power connects to the camera and do it that way cheers Andy

thank you to you both for your replies, i will try the new power cable directly to the camera for test purposes,and if it works fine i will use a new thicker power cable and see if that works, can i test the power to the camera by unplugging the extension cable at the camera connection and putting the tester too the end of the extension cable, my back went at work yesterday, so as soon as i am able to climb my ladder i will try the solutions you both have suggested, many thanks again Andy

i used a 5 metre power and audio extention cable, but the power connector on the cable was only a 2.1mm diameter adapter fitting and the camera was 2.5, so i cut the adapter fitting off the original transformer cable and connected it to the end of the power extention cable and cut the adapter fitting off the extention cable and re joined it to the adapter cable on the end of the transformer, therefore changing the power fittings around to make them fit, using a connector block. but the wires were not the usual 2 cables in there own sleeve when i cut the outer sleeves, the live cable on both cables were in a sleeve, but the negative cable was wrapped around the live cable, just inside the outer sleeve, in a simular way to a tv ariel cable, so i was wondering, because i have done this, the power is not sufficient to the IRs, which is causing the problems i have, Also will be new power supply i have be ok to use with the camera, the output is the same as the original power supply, but the input on the new 1 says 100-240 1.2A and the old one says 100-240 2A thanks again for you help

Hi, i have zoomed in completely and all the IR lights come on, but the picture is still the same,the screen is all black apart from the white light from the street lights, then after a few seconds the camera says no detection and resets itself, thanks for your help i really appreciate it. i also forgot to mention that when the IR is in, the white light it gives off is always flickering, so could it be that there is not enough power going to them Andy

yes it is the power supplied by the supplier, but i have cut it because the connectoers were wrong,the bottom 5 lights work, i checked it by standing outside, looking upto the camera, and i could see the 5 lights showing red, i will upload a pic of the camera thr tope 3 ir lights on each side do not work thanks andy
