Name: Tri-tech Outdoor Sensor
Model: DT-928

Features:
● Dual Microwave, PIR, Intelligent MRD Tri-tech Sensor
● The original Dual Microwave with MRD displacement identification technology: Adopt
cutting edge Phased Array Radar technology to analyze and recognize the shape and
relative displacement speed of any intruding objects. It can accurately recognize the
swing plants, swing wet clothes etc interferential objects and moving human body to
prevent false alarms
● Outdoor application: IP55 rated; 4mm outdoor professional ABS cover is vandal-proof
and anti-oxidation
● Microwave & PIR sensitivity is adjustable to optimize the performance within the
protected area
● Digital temperature compensation: Can auto adjust sensor to ensure effective detection
range and stable frequency
● Adaptive control circuit: Built-in high performance industrial grade microprocessor, can
analyze the surrounding environment on the startup of the motion sensor. Optimize and
adjust the operational parameter to ensure the reliable, stable and effective detection
● High Precision seven curtains Mirrors Optics: Suitable for high temperature, high humid,
strong sunray and salt or fog corrosive environment
● Strong light interference filter system: Reject strong sunlight, lightning, flash light, etc
● High light LED indicator: Use super light LED to ensure to show all day working status
● PhotoMos relay
