After a successful infiltration into the building and a 7 foot drop into the boiler room it took no longer than 2 minutes to set off motion detectors that I had no idea were inside. after a quick escape my partner and I staked out, 20 minutes later 2 police cars showed up and 2 officers got out and searched the perimeter of the building. so. don't go inside.

when the motion detectors went off, were they audible or visible? Or did you just notice them and bail?
