Is it illegal to get videotaped on private property without consent?

A friend of ours bike got double parked. The guy parked like a inch away so when the bike got moved it scratched the car. Anyway the owner of the car sat up a video camera to record this. And is trying to take our friend to court. But He is on private property(an apartment complex) He did not have permission from me or my friend to be videotaped. Also he did not have permission from the apartment management. Can this be used in court? Or do we have the right to file charges against him for recording us?
