Crime Guard AU94T

The Crime Guard AU94T 2-zone, 2-stage radar motion sensor uses radar to detect movement inside or just outside your vehicle. Interior and exterior protection zones are independently adjustable. When the exterior zone is penetrated, a pre-warning chirp results. When the interior zone is entered a full siren blast is triggered. A 30" wire bundle plugs into your Crime Guard alarm brain. Two-sided tape and a wire tie are provided for installation. Dimensions: 2-1/4"L x 3-1/2"W x 7/8"D. Warranty: 1 year. Note: The sensor must be connected to a Crime Guard alarm. It's an option for the 328i and 533i systems, but is included with the 745i system.
