According to their website, Crescent Guard is a BRS Labs partner. Is this something Crescent Guard developed or it just a BRS installation?
I don't think this is anything new or any different than Video Analytics. What's perplexing is their tagline...video analytics can "learn" only based on what a human enters into a system as acceptable or unacceptable behavior. Israel has been using analytics like this for years, but it won't do a thing if there isn't a person actively managing these cameras or responding to an alert triggered by an abnormal action (such as leaving a backpack on the ground).
Systems will never ever replace the needed hands on involvement by humans (well, maybe intelligent robots would someday, like iRobot) to take action so how can it PREVENT crime any different/better than a well-implemented access control or VCA analytics for example?
