Dual Technology Motion Sensors combine two different technologies to increase accuracy and reduce false alarms. They typically use a combination of microwave and passive infrared (PIR) sensors.
Dual Technology Motion Sensors should be installed by a qualified electrician and tested regularly to ensure proper operation.
False alarms can occur if the sensor is installed too close to a heating or cooling source, or if there is too much movement in the detection area.
The sensor should be installed at a height of between 6 and 8 feet, and aimed away from windows and sources of heat and cold.
The sensor's sensitivity should be adjusted according to the environment in which it is installed.
Dual Technology Motion Sensors are not suitable for outdoor use.
The recommended storage temperature before unpacking is between -20 and 50℃, with humidity below 80% RH.
After unpacking, the sensor should be stored in a dry, clean environment with humidity below 80% RH.
Dual Technology Motion Sensors are sensitive to electrostatic discharge, which can damage the sensor and affect its performance.
Anti-static wristbands or gloves should be worn when handling the sensor.
All machinery, equipment, tools, work tables, and material racks should be properly grounded.
Anti-static bags, boxes, and turnover boxes should be used for storage and transportation.
Dual Technology Motion Sensors should be cleaned with a soft, dry cloth.
If a cleaning solution is necessary, a mild, non-corrosive solution should be used.
Do not use abrasive or corrosive materials, as they can damage the sensor.
