I am using the Wildview EZ-Cam. This is one of the earlier versions. I have a total of 10 of these. Yes they do have a plug at the bottom for an external 12 volt hookup. I purchased a bunch of game adapters with the barrel type plug. Some of the wires will have either a grey or white tracer. This wire will go to the positive (+) of your battery. I usually put white electrical tape on it and mark it (+). If you use a meter, the center of the barrel plug and this wire will show continuity. A word of caution: do no hook the wires up in reverse or you ruin that section of your camera. The only complaint on these cameras is the slower trigger speed, but if set up facing along a trail or as some members set up over a feeder or bait, they will work better. Do not face the cameras east or west as this will cause an over exposure or white out. Better to face in a northerly direction. At the present time I have eight of the wildviews set up in various locations. I also recently purchased two SPYPOINT IR-B 7.0 but haven't used them enough to give a valid report. These also have an external port for 12 volt. Hope this helps.
