Tamper-Alert Wireless Motion Sensor

This compact wireless motion sensor uses dual-element infrared sensing to detect human-scale movement with high accuracy. Dimensions are 8.5 × 4.2 × 3.1 cm; weight is under 120g. Housing is made of impact-resistant ABS plastic. Power options include micro-USB connection or optional CR123A battery backup (not included). Communication is via secure 2.4 GHz RF protocol, supporting low-latency pairing with UK-certified smart hubs and alarm panels. The unit features dynamic sensitivity calibration — continuously adapting to temperature shifts and background motion — to maintain reliability in variable environments like drafty period properties or sun-exposed retail entrances. Its integrated tamper detection activates when the device is lifted, tilted beyond 15°, or its casing is opened, instantly pushing alerts to paired mobile apps. It supports automated responses: switching on hallway lights upon entry, logging timestamped motion events for office attendance review, or triggering audible chimes and staff notifications in retail zones. Installation requires only basic screw fixing and one power connection — no electrician needed for most UK domestic setups.
