Henan monitoring / surveillance cameras day and night surveillance video surveillance Name: Wang Tel: 15093372949 QQ: 562817342 1416735265 surveillance cameras during the day picture night no signal here of surveillance cameras during the day are normal, but the evening lights opened, there are two cameras, there is no signal, then restart it after a while, and soon was not any signal, and there is another camera also switch on the power then, and also the machine and fill light to use, but they have no problem, I They also tried to disconnect the power to the camera in question is connected to the same problem. Ask you, thank you! A: There are several possibilities: 1, Henan monitoring / surveillance cameras day and night surveillance video surveillance camera circuit problem has been a problem in itself, enough voltage can barely work, once the voltage problem slightly less prominent. If you do not want to change the camera, then a separate power supply is a workaround. 2, power supply rated current is too small to simultaneously load fill light and camera, this can increase the rated current of the power to resolve. Henan monitoring / surveillance cameras day and night surveillance video surveillance may be your fill light cameras caused too much current voltage is not enough cause does not work, take your camera with a single power supply voltage independent look there should be no problem it!
