Depends on alot of factors. I have a homebrew that is set up for trails, way faster than a Cuddeback, but it does not have toomuch battery or memory capacity. Since it is set up for fast trail use, I use it more for immediate "tactical" value, i.e. real time patterning of current deer movements. It doesn't stay put very long.

A feedercam that is IR and has alot of battery capacity and memory can stay out a long time, generally just swap batteries and cards whenever the feeder gets filled.

It just really varies according to what you are trying to accomplish with the camera.
