The Dahua DHI-ARD1233-W2(868) wireless IR motion sensor is a reliable detector for protecting indoor spaces as part of a security alarm system. The device operates at a frequency of 868 MHz and is equipped with automatic temperature compensation, which ensures stable motion detection regardless of temperature changes in the room. A three-level sensitivity adjustment allows the sensor to be precisely tuned to a specific facility.
Advantages
- Pet immunity — a special filtering algorithm reduces the number of false alarms caused by pet movement
- Three sensitivity levels — precise tuning to the size of the room and operating conditions without additional equipment
- Automatic temperature compensation — stable operation during temperature changes in the room without loss of sensitivity
- Temperature and battery charge monitoring — the sensor itself reports a low battery and when the temperature exceeds permissible limits
- Radio signal level detection — monitoring the quality of communication with the panel for timely detection of interference
- 868 MHz communication with frequency-hopping technology — resistance to radio interference and signal jamming attempts
Applications
- Residential apartments and houses — protecting rooms, corridors and hallway areas when arming the facility
- Offices and administrative premises — guarding offices, server rooms and restricted-access zones
- Shops and retail outlets — motion detection during non-working hours
- Facilities with pets — false-alarm-free security with cats and small dogs
Frequently asked questions
Is the sensor suitable for a room with a cat?
Yes, the built-in pet immunity reduces the likelihood of a false trigger from pets.
How do I know that the battery is running low?
The sensor automatically transmits a low-charge signal to the security panel in advance before complete discharge.
Can sensitivity be adjusted for a small room?
Yes, three adjustment levels allow the triggering range and detection angle to be tuned to specific conditions.
