A wireless intercom has many advantages of its wired counterpart. One obvious advantage of a wireless security system is that you need not have wires running all over the place. This not only simplifies the installation process but also ensures that the whole setup is much tidier. It also gives you the ability to move units easily. If you want to change location of the units, you can do it much faster and more easily in just minutes. Another advantage of a wireless intercom is that you can install extra units much more easily. You can’t do this with a wireless system.

Types Of Intercom Systems

An intercom system basically refers to a kind of home security system gadget that is used for communicating with people within and without a building. Intercom systems come in various types with varied specs and features. Different people choose different systems based on their personal preference and taste. In this section, we look at the most common types of intercom systems.

Carrier-Current Intercoms

Carrier-Current intercom systems are connected directly to the AC power supply of a building. It then creates a medium AM frequency signals. They are pretty much like the hard-wired intercom systems and they won’t give you interference problems. The only problem with carrier-current systems is that they cannot be installed until the construction of a property is completed.

Its audio quality isn’t as strong as that of a hardwired system but it still a great choice for apartment blocks. This is because these intercom systems operate on low frequency which means that the communicate range is a bit shorter. But if you are residing in a landed property, or you want a system to use in a big office building, you may have to look for other alternatives.

Hardwired Intercoms

Another name for the hardwired intercoms is wired intercoms. Wired systems are so named because they wired into the building’s main electrical system. Hardwired systems are best installed during the building of a house. An intercom specialist should work closely with your contractor to decide the most appropriate time to have the system installed.

Choosing to set up the system after the home is fully constructed may present some challenges. For example, you will need to have holes drilled into the walls so that electrical wires can be inserted. This type of system ensures that all the wiring is hidden in the walls. Not only does this look better but it also performs better since there is nearly zero interference. Also, the audio quality is much improved compared to carrier-current intercoms.

Wired intercoms are most widely used in condominiums where the installation is done in the middle of construction of a building. If you want this type of intercom system, it is important that it is done when the property is still under construction.

Wireless Intercoms

Wireless intercoms are relatively late entrants into the industry. Like the name suggests, they don’t require physical wiring. Probably the biggest advantage of wireless intercom systems is that they are quite cheap. In fact, of all the options of intercom systems, the wireless type is the cheapest.

They are also the easiest to install because all you have to do in terms of installation is to put speakers in strategic spots around your house and have batteries inserted into them. However, it is not without its disadvantages. It has a lot of interference. Your system may pick up other wireless system’s signals so that you hear other people’s conversations.

Video intercoms

Today, video intercoms have become among the most popular intercoms for homes. It allows users to not only talk to a visitor but also see them while they are still at the entryway. A video intercom is basically wired since it is not easy to wirelessly send a video feed. The type of a video intercom that you settle for will primarily depend on the features you are looking for and your budget.

Some of the video door phones have a picture memory on which to store snapshots of visitors. In the same way, if you happen to have a good budget, you can choose high-tech video door phone which packs features like pan, tilt and zoom.

Automated gate entry intercoms

This type of intercom system lets you remotely open the door without the need for being physically at the gate to open it for your visitor. It comes with a remote which allows you to open, close and even lock the door right from where you are sitting. These systems come with a video camera which also monitors the person on the door and even footage of them is recorded. Some systems however only allow you to communicate with your visitor but don’t include live video feed.

Features

When buying an intercom system for your home, there is a raft of features that you need to consider. They include the following:

Sound quality

The sound quality of an intercom is very important. The audio control and filtering are very important to ensure successful operation. Also important is the reliability of communication channel.

Echo Cancelling

Most wireless intercom systems use full duplex communication capable of causing feedback and echo. The sound from the speaker needs to be prevented from reflecting via the microphone. This is achieved by echo suppression.

Noise Filtering

Intercoms may be installed outdoors where the noise level may be high. To prevent this noise from interfering with the communication, Bandpass filters will be used to suppress background noises so that the voice frequencies can be heard.

Microphones

A good intercom system should feature directional microphones which help to control noise and at the same time increase clarity.Sound amplification

Another important feature to look out for when shopping for a wireless intercom system is sound amplification. In certain cases, the sound needs to be amplified from the speakers so that the intercom is heard audibly across the room.

Sound frequency range

The average frequency range of many intercom systems is in the range of 300Hz-3000Hz. Most IP type intercom systems support up to 64 kilobyte per second

The average voice frequency range is approximately 300 Hz to 3000 Hz. Many IP type communication systems support 64 Kbps over the network, which supports normal voice frequencies (200 Hz to 4 KHz). There are some paging and intercom systems that support higher frequencies and provide better music acoustics.

Communication Reliability

Wired systems are more reliable than wireless systems. Look for intercoms that have optional communication channels.

Battery Life

Majority of intercom systems use the normal AA batteries. The advantage of this is that you can easily replace the batteries if they run out of charge. Although battery life tends to vary from one unit to the next, go for a unit that has battery life of at least 4 months when in standby mode.

Scalability

When you buy an intercom system, chances are that it will have two units that you can install in your house. But if you want communication to cover more room, you will want to purchase more intercoms. Ensure that the intercom model you want to buy supports scalability. This way, you can add more intercom units as you need them.

Ease-of-Use

Intercom systems vary in terms of intuitiveness and ease of use. When buying an intercom system, look for units that are easily operable by voice or hand, and give you various communication options. The best wireless intercom system will include pager capabilities and also the option to speak with even one respondent.

Fast and Easy Installation

Easy setup is another important feature when buying an intercom unit. You want something that won’t give you problems when installing. To know how easy or difficult it is to install a unit, read customer reviews and also talk to people who own the same kind of equipment as you.
