Secure the open door. Locks are great, but when an access-controlled door is open, your system is blind to tailgating and direction violations. Door Detective® uses advanced infrared technology to detect and prevent unauthorized entry while maintaining smooth traffic flow—becoming your facility's essential door security firewall.
