iamatemple 0 Posted March 20, 2016 A friends old system went down and to get it up till the new system came some wiring needed to be done. Locally I wasn't finding RJ11 to BNC converters so I made some. The cameras were A-CC3MH type in model number and similar A-c*** model numbers. All used RJ11 which went to a multiplexer that accepted that type of input. The multiplexer also had BNC output and converted the signal which then went to a DVR for storage. CCD camera 1 ---> RJ11 multiplexer input ---> multiplexer BNC output (of CCD camera 1) -----> DVR BNC input These cameras labelled "ADT" made in Korea didn't show up anyplace on the web that I looked. Turns out it seems they're made by Ultrak which I found looking for monitor/interphone in hopes of describing the connection type. A poster who I'm not able to credit mentioned they were able to get this type of camera to work using the following: RJ11 pin 1 = Power (-) - bare wire or shielding for video which is ground pin 5 = red - POWER (+) requires 12volt 1amp to work for me though says it can take 15volt 4w MAX DC pin 3 = white foam shielded copper - Video (+) goes to the BNC center pin / solid copper wire on BNC male pin ? = yellow wire which went to the BNC shielding for Video (-) I cut rj11 connector off and did what is below: CCD wiring (was RJ11)___________________BNC male connector_____________________Power source 12v-15v DC 1amp-4 amp MAX Green skinny wire (not used by me) Black skinny wire (not used by me) Yellow skinny wire ====================>> BNC shielding wire / outside of connector (Video -) Red thicker wire =============================================================>> Power source (+) white foam copper solid wire ===========>> BNC copper center wire / center pin (Video +) shielding wires from around white foam copper wire ===============================>> Power source (-) bare skinny wire =============================================================>> Power source (-) This had all the cameras up and working and thanks to flea markets and thrift stores the power supplies were reasonably priced and plentiful.
