## Summary description

The Ajax MotionProtect is a wireless passive infrared (PIR) motion sensor designed for indoor security systems. It accurately detects human movement while ignoring pets, ensuring reliable alarm triggering. The device features a simple installation process with the included mounting bracket and integrates seamlessly into the Ajax security ecosystem for remote monitoring and alerts.

## Long description

The Ajax MotionProtect is a wireless passive infrared (PIR) motion sensor designed to detect human presence within indoor environments. It provides reliable security by monitoring for unauthorized entry and sending immediate notifications to the system owner. The device is engineered to ignore pets weighing up to 20 kg and measuring up to 50 cm in height, reducing the likelihood of false alarms. It is intended for wall mounting in areas where intruders are likely to pass, such as near doors or windows.
Advantages
This motion detector offers exceptional energy efficiency, operating for up to 7 years on a single pre-installed battery. Its advanced digital processing technology ensures accurate detection even in varying thermal conditions, automatically adjusting sensitivity to maintain performance in both hot and cold environments. The system includes robust security features such as authentication to prevent forgery, encryption of communication channels, and jamming detection to ensure consistent operation. Additionally, the device is equipped with a tampering alarm to alert users if an attempt is made to interfere with the sensor.
Suitable for
Securing residential homes and apartments
Protecting office spaces and commercial premises
Monitoring indoor areas where pets are present
Detecting unauthorized movement near entry points
When it may not be suitable
This device is designed specifically for indoor use and is not suitable for outdoor environments where exposure to rain, direct sunlight, or extreme temperature fluctuations could affect its performance. It may also be less effective in spaces with large, fast-moving objects that exceed the pet immunity parameters or in areas with significant thermal interference.
