Close the Door on Unauthorized Entry

Doors with locks provide suitable security, only until they’re opened. Door Detective is a doorway-mounted detection and direction control system that is ideal for any access-controlled area where an intruder could do more than a few thousand dollars in damage. Our Door Detectives remove social expectation from the equation by detecting tailgating, directional violation, and intruders taking advantage of a closing door.

A Comprehensive Solution to Enhance Security

Door Detective is a cost-efficient way to advance security measures without adding hassle to staff and end users. Explore the benefits that a Door Detective can provide to facilities:

Better Protection

Detect “human hackers” and tailgating attempts, safeguard interior entryways and secondary exits, and ensure accurate employee counts for emergency situations.

Return on Investment

With a quick and easy setup, you can save millions of dollars by preventing breaches and thefts from unauthorized access and avoid hiring additional guards or staff.

Improved User experience

Eliminate “politeness pressure” that accompanies tailgating and integrate with any existing access control while requiring no additional authentication.

Gain Control and Accountability

Key benefits include:
  • Tailgate detection – intentional or accidental
  • Direction violations – ensures passage only in the approved direction
  • Population control – helps enforce area limits, and can provide valuable population data to building automation control systems
