I haven't looked in awhile but aren't most wild game cameras still pretty good size, atleast hard to hide, like the size of a paperback book?
Look online or depending on where you live, there maybe a security store, or even wal-mart carries them I think.
But a small CCTV camera which mounts on your porch, preferablly a small one hidden up in a dark corner.
This then connects to a normal TV with a VCR, or DVD recorder, either wirelessly, or with a wire, your choice.
Set it to record, so will begin to record on movement, some will begin to record at a pre-set time, some record continuesly, only problem is, it will record over itself if you don't stop it.
For the price I am really interested in what this one can do.
