## Summary description

The Ajax DoorProtect Plus is a wireless sensor designed to detect the opening of doors and windows. It features an integrated accelerometer to detect shocks and changes in vertical angle.

This reliable security component is finished in white and is suitable for professional alarm systems.

## Long description

The Ajax DoorProtect Plus is a wireless opening detector designed to notify users of the first signs of intrusion through doors or windows. This device utilizes high-end reed switches to detect opening and features an integrated accelerometer that registers changes in vertical slope angle, vibrations, and impacts. It is versatile enough to be installed on roof windows, allowing them to remain partially open for ventilation while still maintaining security. The sensor operates via RF wireless technology and can also function as a transmitter to relay signals from connected third-party wired sensors to the hub.
Advantages
This detector offers robust security through advanced authentication to prevent forgery and encryption of communication channels to protect against jamming. The device is equipped with a tamper alarm to alert users if an attempt is made to interfere with the hardware. With an efficient power management system, the sensor can operate for up to five years on a single pre-installed battery. Its design allows for quick and easy installation using the SmartBracket mounting system, and it can be integrated into the security network with a simple click via the mobile application.
Suitable for
Securing entry doors and windows
Monitoring roof windows left open for ventilation
Detecting vibrations and impacts on glass or frames
Integrating third-party wired detectors into a wireless system
When it may not be suitable
The device is designed specifically for indoor use and may not be suitable for outdoor environments where it could be exposed to extreme weather conditions. It requires a compatible Ajax hub to function, meaning it cannot be used as a standalone security device without the central system.
