I have more experience with scout cams and surveillance systems than I'd like, and think for $60, your best bet would be some fake cameras. And like an earlier poster said, baby monitor and shotgun. I have a few scout cams, one was $75, the others around $200, and I wouldn't count on any of them to catch a bad guy - and the $75 camera has a minimum 10 second delay. The infrared is very obvious on our scout cams, and even with locks, they're pretty easy to steal. The scout cams that don't flash infrared are very expensive, I think they start around $600.
We tried webcams before going all out and installing a closed circuit system with 16 cameras. A fake camera with a flashing light is probably enough to deter most criminals, but we breed a special kind of crazy out here and needed the real deal.
