Range is the biggest downfall of a 360 they dont see as far as a wall mounted detector. They are really only meant for applications where there are a lot of obstructions like a gangway in a warehouse, or arcades where there are lots of arcade machines that obstruct the view of a normal detector. Plus the PIR detects much better when you walk across its field of view, which is why most detectors are placed in corners rather than the middle of a room. Give me a decent Optex quad any day
