Ajax DoorProtect Plus White

Wireless Opening, Shock, and Tilt Detector

The Ajax DoorProtect Plus is a professional-grade security sensor that protects your home or office from more than just basic intrusion. While standard sensors only trigger when a door opens, the Plus model features a built-in accelerometer, allowing it to detect shocks, vibrations, and changes in tilt. This makes it the ideal choice for protecting windows left in ventilation mode or high-value entry points.


Key Detection Capabilities

  • Opening Detection: Uses high-end British reed switches to detect when a door or window is opened.

  • Vibration & Shock: Triggers an alarm if someone tries to force the lock, kick the door, or break the glass.

  • Tilt Monitoring: Detects if a window's vertical slope changes by more than 5°, allowing you to secure windows even when they are tilted open for fresh air.

  • External Input: Includes a terminal to connect an additional third-party wired sensor, effectively making it a wireless transmitter for existing hardware.

Why Choose the "Plus" Version?

Standard door contacts are reactive—they only tell you when a thief has already succeeded in opening the door. The DoorProtect Plus is proactive; it can detect the vibration of a power tool or a heavy blow before the door even gives way.

It is also highly resistant to sabotage, featuring an anti-masking system and encrypted communication that prevents radio interference or signal jamming.
