It seems:
The video would be great in proving violation of your privacy, illegal acquisition of evidence, introduction of illegal evidence into court (if neighbor plays it at trial), and glaring proof of neighbor's trespassing.
It would be extremely beneficial IN YOUR FAVOR if there's a way you can get the video viewed by authorities BEFORE the neighbor realizes it would be a big negative for him. It would be important that the viewing be "on-the-record"--NOT under conditions where police or other officials aren't allowed or obligated to attest to facts via testimony or written report.
If he doesn't show it on-the-record to anyone prior to trial, it may be harder to keep him unaware of the danger to him in showing the video. I think that a basic listing of charges you plan to prove in court does have to be written in your initial filing of charges or initial response to charges in order for them to be part of charges of which your neighbor can be found guilty. If the charges you make are very descriptive, that might warn him against showing the video in court.
