Party consent pertains to audio recording, not silent video recording.
A little OT but related to your statement is our club just got a number of new surveillance cams installed on the various ranges. They all feed back wirelessly to the clubhouse office. There were older units already in place that were supplanted by the new cams. With the old cams, you could barely tell the identity of was shooting. With the new cams, you can read a .22 cartridge box on the bench in front of them.
But to your point: video is retained but it is illegal for sound to be collected so all of the mics are disabled. Which is good because I've been involved in discussions about the club prez and how he is a wienie...

I don't know if he knows how to read lips, though...
For context, our outdoor (only) ranges are member-only, and the range gate is accessed with a RFID card. Aside from Public Day or other occasional events, there are NO RSOs or anyone else on duty--it is self-policed. It is not uncommon to go there and have the range to myself. We are not supposed to confront anyone doing anything wrong (ie: they are armed), just to narc on them.

The few times I've seen bonehead shit, I've gone over and reminded the members of the rules and that they were on camera and that took care of the "problem". In most cases they didn't realize there were cameras.
The biggest infraction I will see, and I don't usually make a deal of it, is "fast" fire on the pistol range. Shots are supposed to be 1sec apart. If a mag dump all ends up on the paper, tightly grouped, I'll comment positively then remind them if one of the club officers is around, they may come over and bitch about it. The plinking (fast fire) range is literally 50' next door so there is really no excuse...
Occasionally, some asshole will put a hole in one of the gongs with an AP round or blatantly shoot up one of the 4x4s used to support the target backstops. While the video is not normally reviewed by anyone (that I am aware of), in those cases it was and the perps found out. They are mum on who it was and what actions were taken but I would imagine repeat actions would result in expulsion. I'd have to read the bylaws...
