Q:There is a surveillance camera, want to adjust the location, hand touch the head, even live, do not know how the matter

Generally the case is the reason for static electricity, in theory, if your camera is using a transformer, that is DC power supply, then basically can be excluded from the leakage caused by the low-voltage (DC12V) camera, if There is a strong power into the words, then the camera will not be able to use, and here to note is not only the camera will have static electricity on your own may also have static electricity, you may say the same two cameras have a One is not, but you have to know the principle of electrostatic discharge, only when you come into contact with the conductive body when the static electricity can be released, you will have the feeling of Ma. In fact, if the camera is used properly, you do not have to worry about whether it is with static electricity, if you really worry, you can ground the camera, the general ceiling has a fire pipe and bridge, you can choose them to ground.
