Wireless Intercom Review

This cordless phone system review will help you a smart choice when selecting a wireless intercom system. There are a limited number of wireless intercom systems on the market as a choice is not as difficult as choosing a different type of consumer goods. There are only three wireless intercom systems that are available.

Power Line Carrier Intercom

A wireless intercom system is not really wireless. Send and receive through the power lines of the house.Westinghouse is one of them. Radio Shack also has one, but they call him a (frequency modulation) FM intercom (I suspect it marks Westinghouse Intercom Radio Shack, so that the product itself). It sends and receives on VHF frequencies, but there it is above the power lines.

These power line carrier communication systems can work well, but it frustrates more than half of people who use them. One of the problems with these systems, with the way your house is wired. E 220Volt come to your house, and 220 two-phase 110 volts is divided, half of your home on stage and will be connected to a half. The problem is that the FM signal is not usually jump on stage, or if they do not do very well. So beautiful that can address system in the middle of your home, with no or bad the other half.

The other problem with systems of this power-line carrier communication that you may have attached devices, which causesInterference with the FM signal. Microwave can be one of the worst offenders. These devices can intercom inoperable. Although these communication systems are cheap and you can try to see if they work at home, are not recommended for commercial environments. There are only two of many devices in an office environment or industry, to make them unusable.

900 MHz wireless Intercom

The other wire on the free market system 900MHz Wireless Intercom System. Asthe name says, it wirelessly transmits in the 900MHz frequency range. This is the only true wireless system on the market. It is not the only one that wirelessly through the ether, but the only one that is battery powered. So not only does not communicate with the wiring of your home or business is not even plugged in, unless you choose to purchase the optional AC adapter.

The wireless system is unique because it has different components at low cost that no otherWireless intercom. He intercoms to the surface of a portable, desk table, desk or sitting. There are two types of this unit with a being called the extreme range of the wireless system. It sends and receives the same path as a field unit is not extreme. Both have a maximum range of 1,000 feet, but you are more likely to get the range of 300 meters depending on the environment. Both devices have the same characteristics.

The wireless system has a waterproof outerDoorbell intercom which can be used outside the front door to talk to people. The beauty of this device is when people press the button on the door, you can talk hands-free.

There is also a waterproof outer intercom, which can be used in any outdoor installation. This requires intercom push of a button for each transmission. Can be hung on the wall or put rubber feet on this device and use it inside if you like. The nice thing is that there is only one large button making it easy to use.

The wireless system also has a built-in intercom, their research system more user-defined. It requires a hole in the wall, but is battery powered so no wiring is required. Battery life in all units of wire-free 1 to 2 years, so do not need much battery.

The system has a free wire VOX and monitors that not all wireless phones. It 's like a baby monitor> Monitor mode. The difference is not always monitor. Only when your microphone picks up sound, loud enough to the microphone to the series. There are three different levels of sensitivity to activate the microphone, but even in its most sensitive setting, it is not good for the faint voices of more than half a meter a microphone. The disadvantage of using the monitor mode for some applications is that it is horizontal, an aural signal receptionwhenever the microphone is on. If that were the sons to be monitored, this would be annoying to have fast enough.

If you insert a device to tie in free VOX mode, when someone from another unit, the unit calls in VOX mode, they can answer hands free without pressing the Talk button. A problem that has two radios, VOX that have divided, that there is a slight delay in transmission during the VOX circuit passes the microphone to handle. Radio operatorswhite, as indicated by the repetition of the first word or two to overcome, but for the average person, this delay is a bit 'frustrating.

A unique feature of the free wire system is its ability to do private interviews. The units must be "taught" to speak with each other. Once this is done, even if the neighbors have the same device, can not hear or talk to you. Even if a page is broadcast to all units, the system wirefree established a private conversation between the issuer and thePerson who answers, so you do not hear about all the other units, the conversation.

MURS wireless intercom

Yet another wireless intercom system is not so much by a computer from a manufacturer because it is a set of wireless intercom systems and wireless devices. This "system" is set to the radio frequency products that are compatible with Murs. MURS stands for Multi-Use Radio Service and is a two-way radio service consisting of five frequencies in the VHF (Very High Frequency) spectrum. Unlike mostFrequencies in the VHF MURS FCC license is not required for operation.

Although there are only 5 channels, each channel between a 38 "soft code" or sub-channels to choose not to hear the calls from other users on that channel. Just listen to the radio calls from the same channel and code to calm radio. In most areas of the MURS frequencies used very little, then you will not find a lot of competition for the airwaves.

The largestMURS advantage is the variety it offers. Some manufacturers claim a range of four miles. Of course, this is the track is a line of sight, no obstructions between the intercom systems. The area is also in these communication systems by an external high-gain antenna on top of your home, business or car if you are using a device there should be increased.

The beauty of MURS is that you get a portable radio, commercial vehicles and communications systems outside of the base station / console, and also motion detectors thatPost a verbal warning to other devices Murs. For commercial, industrial or commercial systems with MURS can win because a lot of problems and obstacles these applications.

If you need a wireless AP (public address) system, there is a wireless PA that works with all radios Murs. For retail businesses, services directly to customers, there is also a MURS wireless device that allows customers to call for help from a button and pressa transmission record your message.

Since each manufacturer to create a wireless device murs, MURS choosing a system that prevents you choose to offer products from a particular vendor locked.

Regardless of the wireless intercom system you choose, give you comfort and security that must be installed quickly without problems.
