IP44 Waterproof Wireless Doorbell 300m

Transmitter dimensions: 6.5 × 3.2 × 2.1 cm (85 g); receiver: 12.5 × 7.5 × 3.8 cm (220 g); power: 2 × AAA (transmitter), UK mains (receiver); shell: UV- and impact-resistant ABS; IP44 certified for dust and water resistance; guaranteed function from -10°C to +50°C. The 300-metre wireless link uses robust frequency-hopping technology to minimise interference from Wi-Fi routers, microwaves or neighbouring doorbells — essential in dense UK housing developments. 58 chimes include adjustable tempo and pitch variants, and volume control spans four clearly differentiated levels (65/75/85/100 dB) — allowing fine-tuned adaptation for hearing aids or open-plan living. Blue LED illumination activates within 10 ms of button contact, visible even in daylight through frosted glass or narrow hallways. Installation is genuinely universal: receiver fits any UK socket; transmitter attaches cleanly to wood, metal, brick or PVC — with no damage, no mess, no maintenance.
