I have a couple of Stealth Cam, model #STC-FX12CMOK, that, when I turn them on just take pics at 1 minute intervals until either they fill the SD card or deplete the batteries. Any clues as to how to prevent this? I contacted their customer service and all I got was a boiler plate telling me to do those things I was already doing--use SanDisk and lithium batteries. Maybe I missed something in the instructions or these aren't motion activated. I have 2 and both act this way--traded my old D cell cams at Dick's for them.
