Ajax Grade 3 motion detectors

Ajax Systems Grade 3 Motion Detectors – EN50131 Certified Intrusion Detection

The Ajax Grade 3 motion detectors are designed for security installations with an increased risk profile. These detectors comply with the EN50131 Grade 3 standard and offer maximum reliability, tamper protection, and detection accuracy for high-risk objects.

They are suitable for applications where a standard Grade 2 solution is not sufficient and where insurers or risk assessments explicitly require Grade 3.

What does Grade 3 mean for motion detection?

Grade 3 has stricter technical requirements:

• Increased tamper and masking detection

• Protection against manipulation and shielding

• Advanced anti-jamming monitoring

• Continuous system monitoring

• Higher resistance to professional intrusion methods

This makes them suitable for environments where organized or targeted intrusion poses a real risk.
