An intercom has become a popular way to provide added safety and security inside and outside your home. An intercom is an electronic communication device between rooms or areas in a building or buildings. An intercom in business use might allow for public address announcements, or shift end bells. A home intercom often links several rooms within a house, and may be one way or two-way. For example, you may be able to hear your children in the bedroom or playroom from the kitchen, but they may not be able to hear you. If the intercom is two-way, either end user will be able to send or receive.
A home intercom system is helpful for communicating between the house and garage or workshop. Sometimes a home intercom system would be used for communication between a house and guest house or apartment, or between the house and an entry gate.
A cordless intercom serves in much the same way as a cordless phone. A cordless intercom can be used in a home or business wherever mobility is necessary or desirable. Cordless intercom systems are great for multi story buildings such as schools, hospitals, or offices. A wireless intercom can be plugged into any wall outlet and works on the electrical lines in the building. A cordless intercom does not require any additional wiring or coding in order to operate efficiently.
The transmit range of a cordless intercom will vary depending on the strength of the wiring to transmit, and the quality of the unit itself. Only one pair of a cordless intercom system can be operating within its range at the same time.
Another primary use for a home intercom is as a door intercom system. Often this home intercom is used where you want to identify visitors before opening security gates and allowing them into your property or home. An intercom can also be used to allow someone to announce themselves at an apartment house door in order to be allowed into the building. Sometimes a doorman will use an intercom to check that the apartment owner is expecting the guest before they are allowed to proceed further
Whether they are used for home, business or factory applications, an intercom helps maintain communication between two or more users spread out over geographical locations. An intercom can be used for saving steps, for safety or for security. They particularly make an effective addition to a total home security system.
