is it legal to video a neighbor on their property without proper legal consent

In Ontario, it is not as long as one party has consented. In short, if you are doing the videotaping and you are a party to the conversation, it is legal. You cannot tape anyone without their consent if you are not a party to the conversation.

No, it is generally not legal to videotape people having sex without getting consent from all the parties involved. The individual states have their own laws, and there is also a federal law the prohibits video taping someone (without their consent) under circumstances in which that individual has a reasonable expectation of privacy, regardless of whether the individual is in a private or public location. For Indiana take a look at Ind. Code Ann. § 35-45-4-5. Under that statute, "clandestine" or "surreptitious" video taping is considered "peeping". A prosecutor would only have to prove that a person on the tape was not aware they were being taped.
