Ajax MotionProtect Outdoor motion sensor

Dimensions: ~183 × 70 × 65 mm; weight ~318-322 g

Height of installation: 0.8-1.3 m (recommended ~1 m) using SmartBracket – QR-based pairing with app.

Setup assistance: remote tests (e.g. signal strength), sensitivity and range adjustments directly from the app.

General information

• Type: wireless IR-PIR sensor, suitable for both indoor and outdoor use.

• Working range: adjustable 3-15 m (at installation height ~1 m), horizontal viewing angle 90°.

• Detector elements: two PIR sensors ensure dual detection – alarm is only activated if both sensor elements detect motion simultaneously.

Advanced technology

• LISA/SmartDetect algorithm: two-step processing – first comparing signal synchronisation, then spectral analysis. This eliminates false alarms (e.g. foliage, insects, wind movement). lemona.ee.

• Pet-immunity: ignores animal movement up to ~80 cm in height

Sabotage and mask protection

• Grade 3 anti-masking: detects a variety of sabotage attempts – such as sensor overshoot, locking masks, over-painting, etc. – and reacts immediately.

• Tamper: notifies removal or opening of the housing.
