Ajax MotionProtect Plus Jeweller Motion Detector - Black
The black Ajax MotionProtect Plus Jeweller is a wireless indoor motion detector that uses both a PIR and a 24 GHz microwave sensor, which helps it ignore heat-related false alarms in sunny or warm rooms.
Key features
- PIR sensor plus a 24 GHz K-band microwave sensor, so both must see movement to avoid false alarms from thermal interference
- Detection distance up to 12 m at 2.4 m installation height; 88.5 degree horizontal angle
- Pet immunity for animals up to 20 kg and 50 cm height
- 3 sensitivity levels set in the Ajax app
- SmartDetect algorithm; effective detection from -10 to +40 degrees Celsius
- Tamper alarm and device authentication
- Jeweller radio range up to 1,200 m in open space
- 1 x CR123A battery (pre-installed), up to 5 years of battery life
- 110 x 65 x 50 mm body weighing 96 g
Where it fits
It is a good choice for rooms with heat swings, such as a sunroom, a kitchen near a stove or a lounge with afternoon sun, and for homes with pets. It suits houses, townhouses, offices and shops. The black body suits dark walls or ceilings. The detector runs on its own battery rather than the mains. Indoor use only.
Works with
- Ajax hubs and range extenders, over Jeweller, Ajax's encrypted two-way radio protocol
- Ajax apps for setup, configuration and alerts
- Exact hub model compatibility is shown in Ajax's own compatibility checker; ask us before ordering if you are unsure
