Hello. I purchased several amazing spy cameras that have three circuit boards screwed together with posts separating the circuit boards. These particular cameras have a third lead for data. For a keypad, actually. One lead for the 12VDC, one lead for the picture transmission and a third lead for a keypad. There are 5 little buttons on these cams so you can make an amazing amount of changes. Just so you don't have to get up and walk a long distance and to make adjustments where the cam is actually going to be placed, a third lead was included so you could make adjustments with a keypad at the other end of the cable. I'm sounded redundant. Well, no matter how I beg the people who sold me the cams, they will not give me a source to purchase the keypad. Anyone got any sources? I Googled until I went insane but no results. The people I bought the cams from will NOT tell me who their wholesellers are!! I tried to find wholesellers but to no avail! Please help!
