hi, i wonder if any experts here can advice me what is wrong with this IR cctv camera that i recently bought. it's has this huge dark double black line not flickering but moving either up or down, this happens when it's in the night ie. when the IR led's are on.in the day time there is still this double lines moving around. by judgin the pics i attached here i hope someone can help me out. Thanks in advance Rayne

yes it's definitely the power supply, had it changed and the lines were all gone!. the camera i was talking about has IR leds 24. there is another problem im having. can anyone fix camera's if they are damage or burnt? there is another black bullet camera no Ir led got burnt the other day due to wiring problem. i had it opened and can smell its burnt. just thought i'd post the pictures for you all to see and if anyone know or any idea to fix it.(by the smell i think it's from the black round coil of wires inside that box in the pic.(are they the coil or resistors or fuse?) i bought it from maplins and been using it for over 3 years, it was an expensive one when bought 3 years ago, think it was around £70.

the camera is about a meter cable with BNC plug, with an BNC to RCA adapter i connect it directly to the tv to test it. it's not ground loop since i've tested it. the power input said on the camera spec is 12V 500ma. i test the power by using the 3v-12v power adapter and set at 12v. i decrease the voltage to 9v and the black line gets smaller by a lot!. i set the voltage lower to 7v and the line is gone!. so wut's really the problem? the working voltage should be 7v and not 12v? will it not be enough power to power on the IR leds? by the way this only happens at night ie. when the IR leds lights. in the day the camera is fine with 12v.. since that sorts the problem i'll need to get a 7 or 9volt output adapter. it's all thanks to VST_Man and scorpion, you two are real pro!
