Technology has come a long way and it is more common to find door chimes that don’t just represent the average person but for people who cannot hear well if at all. This can prove to be a lifeline for some.
Whilst you would not be able to purchase an ordinary chime, there are visual ones available for an affordable price. The system is plugged into a mains adaptor and like a normal chime, it still produces sound but also flashes for about 10 seconds should someone call round.
