I purchased a cheap camera and the manual was less than helpful. After several emails with product support my question was not resolved. I am hoping someone here can help me. I would like to know if the sockets labeled Z F C are for a remote switch setup for zoom focus and C (I'm not sure what this is for). The A B i know is for another 12 v power connection which I assume is for the motor within the camera to operate the functions. I have attached a picture as this is a general camera purchased from overseas. Any help would be appreciated.
