Visitors can call and talk easily with residents through the unit downstairs in front of the host, and the residents can control opening and closing of the unit indoor. The community alarm host can receive the alert from the residents at any time and send it to the host, and then notify the community security guards on duty. The system not only enhances the high-rise residential security work but also greatly facilitates the residents and reduces many unnecessary troubles. Moreover, with wireless doorbells, people do not need to worry about the running out of batteries, nor do they have to change the battery regularly. The only trouble is the power failure. But now some wireless doorbells have been able to generate electricity by themselves, and the power failure does not affect the use.
