A friend of mine is trying to catch a suspect money thief from an office desk draw.
He wants to capture images of the thief, The cleaners are suspected so its happening overnight.
What options are available? He doesn't have local admin rights to install any software. Ideally battery powered but not adverse to electrical socket. He had a non descriptive brand of camera from eBay but it failed last night so without spending anymore money on it then I am looking at better alternatives.
