A clever security camera perhaps?

[DickWilson]

I use two similar models from cabella's that work quite well. There are also infrared models available that use an invisible flash. Search for game camera's on their web site. prices range from $50 up. With a large capacity SD card they store a large number of photo's, Most have a laser aiming beam for precise alignment. I get license numbers and photo's of anything entering the property. Enclosures are weather proof and easily concealed.
