Visual Alert Doorbell For Deaf

This wireless doorbell system consists of a weather-resistant touch transmitter and a portable receiver powered by 3 AAA batteries (included). The receiver measures 12.5 x 7.5 x 3.2 cm and weighs 180 g; the transmitter is 9.5 x 5.5 x 2.8 cm and weighs 95 g. Both units are made from durable ABS plastic. The transmitter features IP44-rated protection for reliable indoor and outdoor use, with high-sensitivity touch activation and low power draw. The receiver delivers visual notification via bright built-in LED flashing light, plus 36 melodies and 4 adjustable volume levels (mute, low, medium, high). Its wireless range reaches up to 1000 ft in open space, with anti-interference design to prevent signal conflict with Wi-Fi routers, cordless phones or neighbouring doorbells. Installation requires no wiring: simply insert batteries into the receiver, remove the insulating tab from the transmitter, and mount or place units as needed — avoid metal surfaces and proximity to TVs or other electronics.
