One of the first things to consider when buying an intercom system is whether you will need video capability or not. Basically, video enables you to see the person you are talking to and can be used much like a security camera.


Whether it's a hospital, school, or office complex, the buildings can sometimes be several floors high and have sometimes hundreds of rooms, which can make it really hard to keep in touch. Fortunately, an intercom system can connect all of them, making it easy to communicate throughout the building.


When it comes to both hard wired and wireless intercom systems, you have plenty of options to choose from. This includes party line systems and matrix systems, as well as the development of an interface with your home phone system.


Modern intercoms feature state of the art technologies. The same was true for speaking tube intercom systems in 1851: “Gutta percha is a most desirable substance for the tubing, as it possesses a remarkable sound-transmitting quality …” (Granville Sharp, London Exposition technology review)


One thing to consider when it comes to buying a wireless intercom system is what type of interference your system may be susceptible to. Things to look at include cordless telephones, wireless data networks, and baby monitors.


When it comes to intercom systems, one thing that you need to keep in mind is privacy considerations. If privacy is a priority, look for a system that has an isolation function, which will let you communicate with a specific station without broadcasting the entire conversation around the home or building.


There are several things that you will need to keep in mind when choosing a wireless intercom system for your home and business. This includes you current needs as well as the wireless products that already are located on site.


Modern intercom systems can provide users with a host of applications, from music, video and clear communication. Large homes benefit from these systems in terms of communication and an extra layer of security for your family.


Did you know that the United States and Canada have several frequency ranges for wireless intercom systems and other wireless products? These are 49 MHz, FM band (200KHz-270KHz), 900 MHz, 2.4 GHz, 5.8 GHz, and 150 MHz.


Automated gate entry intercoms enable you to open a door or gate located at the perimeter of your property remotely. Usually, these systems come equipped with a video camera, which enables you to monitor the person at the gate.


In office settings, some intercom systems were designed for direct communications and used to dictate letters to stenographers and secretaries. As early as 1907, one intercom manufacturer, the Dictograph system, was integrating these special features into its technology.


If you want to make sure that your intercom system is secure, then you might want to consider a hard-wired system. Most wireless systems work on open frequencies which can be overheard if someone tunes to the right frequency, while a wired system is a closed system.


Assisted living care centers almost certainly should have an intercom system in place to keep communication instant between caregivers and residents. This is not only for security reasons, but the safety and health of everyone in need.


Traditional door intercom units were usually audio only, but today it's easy to get a system with audio and video. The audio and video are usually activated when the person presses the buzzer, making it easy for you to see and talk to the person at the door.


The word “intercom” didn’t come into use until the 1940s. It emerged as an informal, shortened version of the phrase “intercommunication system,” but it quickly moved into widespread use shortly after the first truly modern system was introduced in 1936.


Intercom systems are wired to stations throughout your building. These can either be two-way stations, or one-way loudspeaker stations. Either way, these stations make it easy to make announcements to the whole building or just to specific rooms.


With a carrier current system, the intercom signal is going to be carried along with the electricity in the building or home. While the quality of sound isn’t as good as a hard wired system (due to the shared nature of the wiring), these systems tend to be much more affordable.


Intercom systems are very useful for many types of businesses, schools, community buildings and private homes. Easy communication at a press of the button can improve the quality of your communication and increase safety for everyone in the building.


Office complexes and office buildings often need to have a lot of security, especially after hours. Intercom systems can be a vital part of building security. Not only can they make it easy to keep your security agent in touch, video/audio intercoms can be put at all entrances.


Intercom stations used to only be fixed stations with no mobility, but that has changed in recent years. Modern stations can be made with a portable telephone-style speaker and mic. They can also be made with a belt-pack station which can either be hooked to a headset or earpiece.


Did you know that years ago 2-wire intercoms were half-duplex only, which means only one party could talk at a time? However, new developments in technology have made it possible for even 2-wire systems to have full-duplex communications.


In the early 1900s, many intercom systems were based on telephone technology. All telephones at that time were point-to-point systems, so a direct line had to be installed between every office, room, facility, or location to make quick, internal communications possible.


The speaking tube, a precursor to the intercom system, appeared in literature as early as 1839. Charles Dickens wrote that “the voice of Madame Mantalini, conveyed through the speaking tube, ordered Miss Nickleby up stairs.” (Nicholas Nickleby, 1839)


Hard wired intercom systems are run behind the walls of a building, so it's usually best to installed them during construction or remodeling. One of the big advantage of these systems is their reliability, since the wires are much less susceptible to interference.


Intercom systems can be wired or wireless. If you are building a new home, wiring the intercom system will ensure that you have a stable system in place that cannot be disrupted by other wireless signals.


Did you know that some intercom systems have the capability of playing music across all the stations? This can be a great addition to your home, especially if you don’t have your house wired for whole house sound.


If you have mobility issues, it can be tough to get around your house and talk to people. Fortunately, intercom systems make talking to each other easy. Wireless intercoms can even have remote stations that you can keep with you.


Did you know that most wireless intercom units have an average range of about 1,000 feet? One of the biggest advantages of these types of system (beyond their ease of installation) is their portability, as the units are battery operated and thus can be used practically anywhere in range.


The most common type of intercom system for homes is the wired, audio only intercom system. These have a variety of uses, such as inter-house communications, front door security, or as baby monitors. They can be anywhere from a single speaker to multiple units.


One feature to look for when it comes to intercom systems is a hands-free feature. This offers an extra level of convenience, as you are able to push a button, let go, and then talk to a person at another station without having to hold that button down.


Any care facility will benefit from having an intercom system in place. This will allow caregivers to communicate with patients quickly and efficiently. This is a major safety bonus that can improve the living situation for everyone.


Intercom systems offer many options beyond the basics. You can contact someone in another room, they can contact you, you can monitor the entire house as a security measure, or activate privacy settings to minimize disruptions.


Door stations can only make calls to the master station in an intercom system, which makes them similar to sub-stations. The one difference is that door stations are usually positioned outside the entrance or door, so they're usually made to be weather-proof.


When choosing between a wireless and a wired intercom system, research the drawbacks and benefits of both systems with regards to your situation. Wireless systems can experience disruptions from other wireless signals such as cell phones and television.


Early intercoms: “Two persons standing at each end of a simple tin pipe, 1 inch in diameter, 50 to 100 feet or more long, with several elbows in it, and carried through a half a dozen rooms, can still converse quite readily in a low voice.” (Manufacturer and Builder, 1872)


During the 1800s and early 1900s, voicepipes were popular intercom systems, but they weren't used everywhere. Some executives preferred to talk in person, and chose room-to-room buzzers instead. Fortunately, intercom systems are much more popular in modern offices.


Carrier current intercom systems rely on AC electrical systems in order to produce medium frequency signals. While the audio quality won’t be as good as that of a hard wired system, this is a convenient way to facilitate communication across a building or home.


If you are tired of door to door salesmen, then you will benefit from having an intercom system within your home. An intercom system allows you to communicate with visitors before they enter the house, giving you peace of mind.


The Metaphone, an early phone-based intercom system, was introduced in 1905 with this ad: “How would you like to simply put out your hand, unhook a small device, and be in instant communication … The Metaphone enables you to do this.”


The Biltmore Estate is the country’s largest private residence located in Asheville, North Carolina. The home is a massive 175,000 square feet, and was completed in 1895. This home has a taste of modern technology with an intercom system throughout the entire building.


Hard-wired intercoms have to have their own lines run through a building, which is where carrier current intercoms come in. They're installed by being integrated with the existing wiring of a building, and use the electricity to produce the signals.


One type of wired intercom system is the Cat-5 System. These utilize a specific type of bundled wires (also used for data networks) and enable digital communication between stations and all the extra features that can accompany this.


Keep in mind that if you are going to invest in an intercom system, most systems come with only two stations. Therefore, you will need to purchase additional stations if you want to use the system in more than two rooms.


If you've ever lived in an apartment building with a buzzer, you're familiar with the wall mounted station, especially in older buildings. This station is fixed into the wall, and has a built-in speaker and mic. These often have a push-to-talk button or handset.


Copper wiring is so adaptable it handles heavy duty power generation and industrial loads, but it also adapts to the lower loads required by intercom systems, electronics and telecommunications. It’s a good choice in homes as well as commercial buildings and industrial facilities.
