An intercom (intercommunication device), talkback or doorphone is a stand-alone electronic communications system intended for limited or private dialogue. Intercoms can be portable but are generally mounted permanently in buildings and vehicles. Intercoms can incorporate connections to walkie talkies, telephones, cell phonesand to other intercom systems over phone or data lines and switch electronic or electro-mechanical devices such as signal lights and door latches.
Intercoms are not to be confused with "Telephone Door Entry" systems, where the 'Intercom' facility is an option available on a system in which instruments within a building can be used to intercommunicate with each other (usually a single-dwelling), or where apartments can communicate internally with a resident porter.
Grupo Intercom was created in 1995.
Grupo Intercom's motto is 'We innovate with values and efficiency'.
"The principal spoke loudly over the intercom."
The authorities in Spain have not banned Intercom so it can be used. Motorcycle owners can use the Intercom system since it is versatile and reliable.
You can purchase a business intercom from ServiceMagic, eBay and Quantometrix, Teleccommunications. You can also go to Yell and find businesses that sell business intercom systems in your local area.
Although wireless intercom systems do serve the purpose there are some drawbacks. A wireless intercom system can be vulnerable to both radio interference and security issues. With wireless intercom systems conversations can be picked up by scanners, cordless phones or baby monitors that are on the same frequency.
It operates exactly the same way as any other intercom. The only difference is how it gets its power. As an example, the intercom at the following site can run on battery power, AC power, or it has a solar power option. Whatever intercom you use, you'll have to consider that an intercom near a doorway may be shielded from the sun so the solar panel will likely have to have a long cord on it. You may be able to find some sort of solar panel you can use to convert any battery-powered intercom to solar. Just look for one that has the right voltage and current output to match the intercom.
This depends on how you are as an individual at wiring projects. If you understand the intercom wires and how to hard wire them throughout the house then it may not be difficult.
