To catch a thief, Advice needed

["Dave" <davidclark@xxxxxxxx>]

We have a thief working at our company. He is very reliable and because
of this, I think we can catch him on video.

What I want to do is install a hidden camera with a recorder and set
out some bait in front of the camera.  Of course, my budget is limited,
so I am looking for advice on how to do this the most inexpensive and
easy way.

Everything I have seen at the security websites are overkill. I only
need a single channel of video, with the capability to record at least
1 week, but preferably 2 weeks with good resolution and at least 1
frame per second.

I am also wondering about installing the camera.  I need a small
camera, but good image quality in order to identify the culprit. But I
have to hide the thing of course. I was thinking about using a fake
mirror (mirror glass) but I'm not sure where get something like this.
Or maybe one of those fake clocks or something with a built in
camera....

Thanks for any help....
