The missing link in access control

Access control systems only control when a door is unlocked; Door Detective takes it one crucial step further by preventing unwanted intruders from tailgating behind authorized staff.

The infrared beam arrays work similar to the neural network found in Fastlane turnstiles, to ensure only authorized users are granted access. As such, Door Detective is recommended to further optimize any substantial entry security investment. Door Detective is available in three models: CL, Compact, and Plus.
