We’ve just fitted a new outdoor security light with PIR movement sensor for a customer. Nothing new in that – except…!
This one detects a person, switches on the light, then the light turns to face the person, then can pan from side to side, effectively “following” them whilst they’re in range. Whilst there’s a slight hint of “Dalek” about it, you can’t help but accept it’s probably better security than a normal light.
