I tried using this to capture images of creatures moving along the creek behind my house. I didn’t capture any, so either there were none, or I didn’t push the buttons in the right sequence. So I moved the camera to the front of my house and was able to capture the migration of the trash collection and recycling trucks past my house. I seem to be getting a lot of false triggers, probably due to tree branches moving in the wind. I used a Samsung 32GB microSD Select card that I purchased through Amazon to store the data and that combination worked. I used 8 AA batteries to power the camera, but it is my understanding it can work with 4. I assume that 8 would run the camera for a longer period of time. There is a 3 positon switch for off, test and on. Moving the switch to the test positon allows the adjustment of the setting for still image resolution, delay and video duration among other things. After settings are complete, I pressed the OK button and then the shot button, then moved the switch to the on position. This sequence seemed to work. Just moving it to the on position didn’t, even if the settings had been done before. I was in need of instructions for an idiot.... push this button...do this next sort of thing. Still it did work and I got lots of pictures.
