70m Range Wireless Door Chime System

Dimensions: sensor unit approx. 9.5 x 5.5 x 3.5 cm; receiver unit approx. 12 x 7 x 3 cm. Weight: sensor ~85 g, receiver ~150 g. Powered by 3 x AAA batteries (not included) for the sensor; receiver plugs into standard UK mains outlet (no battery required). Constructed from durable ABS plastic. Infrared sensing range: 3–7 metres; wireless transmission range up to 70 metres in open space. Offers two operating modes: LED Flash + Sound, or LED Flash only. Volume adjustable across three levels (25–80 dB), indicated by LED lights (High/Middle/Low). Includes 38 distinct chime melodies. Designed for indoor and sheltered outdoor use only — not waterproof; must be protected from rain. The passive-infrared (PIR) motion sensor reliably detects human-scale movement within its field of view, triggering the receiver instantly. Ideal for alerting when visitors approach doors, entrances or thresholds — whether at home, in a small office, guest house, warehouse, or retail shop front. Particularly useful for business owners working out of sight, or for notifying when pets move near entry points. Suitable for mounting on walls or placing on flat surfaces. No wiring required — fully wireless setup. Receiver fits any standard UK socket. Sensor placement is flexible: position it at entryways, hallways, patios or driveways where early detection is beneficial.
