The Visit smart home systems are important alerting devices which help keep tabs on your home. A combination of transmitters, receivers and accessories are included in the Visit system that can be placed or carried around the house to alert you from any room of important warnings and notifications, such as guests at the door; telephone ringing; baby crying; activated smoke or carbon monoxide alarm. The Visit System for the Deaf, hard of hearing and heavy sleepers will especially appreciate that the radio signals are transmitted wirelessly and you will be alerted by flashes of light, varying loud sounds or strong vibrations from receivers. Depending on your needs and preferences, these alerting devices will help you stay connected and safe every day and in emergency situations.
