So you have cameras on your house. Are you watching them 24/7? No, otherwise you wouldn't be able to do anything else. Systems like Ring and even the software for full camera systems can notify you when they detect something. Great, too late as the coppers are already beating on the door. I'm not sure how effect that is.
Better money would be spent on a police informant that could tell you a raid was being planned. Even if you have 24/7 monitored by humans video feeds, by the time the raid was visible in the video feed, they are already there. That's my point
