This thing is amusing. The one advantage it has over in place cameras is that it can try to go get a better view of the perps’ face, especially if it had a camera pointing up for hoodie wearing perps. But it’s probably not agile enough to manoeuver like that.
Maybe the annoyance is enough to chase away burglars and such —they are actively reminded they’re being recorded and it’s not as easy to de-energize and disconnect as regular home sec cams.
