Best setup for recording ufo's from my backyard?

I am interested in setting up a camera in my backyard to see if I can capture any ufo footage. Much like a security camera that record's all the time so you can go back and review the footage. Would a cctv camera be best and if so, what kind? Can anyone point me to the best (although economically practical) setup for doing so?

alot of people add an infrared camera or lens to their setup, as often it shows stuff we cannot see with the naked eye.
