## Long description

The Dahua Technology ARD1233-W2 Wireless Wall Passive Infrared Sensor is a battery-powered motion detector designed for discreet wall mounting. It detects movement by sensing changes in infrared radiation and communicates wirelessly on the 868–868.6 MHz band. Constructed from durable ABS and PC materials, the sensor is intended for reliable, long-term operation with a CR123A battery that provides up to four years of typical service life under normal conditions.
Advantages
The wireless design removes the need for wiring to the control panel, simplifying installation and allowing flexible placement. Low-frequency operation at 868–868.6 MHz provides stable communication in many residential and commercial environments. The compact white housing and robust plastics resist everyday wear and are suitable for visible wall mounting. Long battery life reduces maintenance intervals and lowers operating cost over time.
Suitable for
 Residential interior rooms such as hallways, living rooms and bedrooms
 Commercial indoor spaces including offices, reception areas and storage rooms
 Integration into wireless alarm systems for perimeter or interior motion detection

How to use
Choose a wall location that provides a clear view of the protected area and mount the sensor at the recommended height for motion detection according to your system documentation. Insert a CR123A battery following polarity markings, pair the sensor with the compatible wireless alarm panel or receiver using the panel’s enrollment procedure, and perform a functional test to verify detection coverage and wireless connectivity. Adjust mounting angle or position if necessary to avoid false alarms caused by heating sources, air vents or direct sunlight.
Usage recommendations
For reliable operation, test the sensor periodically and replace the CR123A battery when the system indicates low battery. Avoid installing the sensor near strong heat sources, direct sunlight, or moving objects such as ceiling fans. Maintain clear line of sight within the monitored zone and clean the exterior housing gently with a dry cloth to prevent dust accumulation that could affect detection performance.
