Put your cameras on at least a 4-hour delay under the remote control setting. This allows the wireless module to enter a “sleep-mode” for a longer period of time. (We run our cameras on a 24-hour delay here at Covert and they’ve been out in the field for over two months.) You will continue to receive pictures when the camera is triggered by heat or motion, you just will only be able to do the settings changes or real-time control every 4-hours (or every 24 hours if you choose the 24-hour delay, etc.)
