Guys, my neighbor's bedroom window is 50m away from mine and she often doesnt pull her curtains. The window is 3x3m big.

I plan to put a camcorder/dslr behind my wnidow, concealed by curtains, and let it record for several hours straight. I want to get the best detail possible. My budget is about $800.

Pls give any recommendations for camcorder or DSLR+lens. Or, at least, let me know which parameters on the product (lens size, etc) matter and how it works. I can then figure out what to buy.
