The Missing Link for Interior Door Security

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. Door Detective is a cost-efficient solution to advance security measures without adding hassle to staff and end users.

Explore the benefits that a
Door Detective can provide to your facilities:


Detect “Human hacking”, safeguard interior spaces, and ensure accurate employee counts for emergency situations.


Save millions of dollars by preventing breaches and theft, avoid adding additional guards or staff, and ease of installation.


Eliminate tailgating and integrate seamlessly with the ReconaSense platform while requiring no additional authentications.

Gain Accountability and Control

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
