Cordless Telephones

Once we have decided to create a new wireless intercom system to increasing range of wireless devices in the home or office, you must think first of compatibility with the products they already have (or your neighbors). You should also take into consideration the size and features you need.

Wireless Intercom Frequencies

In the United States there are several equalizer for wireless products for consumer use without a license. Are 49MHz, 900MHz, 2.4;5.8GHz, and Family Radio Service (FRS) band. The FCC then added Multi-Use Radio (MURS) service. Radio equipment is the same in Canada, but Murs is not used.

Return to the wireless consumer products have been launched, these wireless products used to 49MHz frequency spectrum. Early cordless phones using this spectrum, and is still used by baby monitors at low cost and low-end of other wireless devices. Has a short range and are prone to manyinterference. It is probably not wireless intercom systems that use this spectrum to find.

Later, 900 MHz, using analogue technology transfer products, new market. Neither the 49MHz and 900MHz these early products need some form of security. Anyone with a unit in the same frequency can hear the conversations. Newer 900MHz spread spectrum digital broadcasting digital divide of the product on a range of frequencies so other devices can intercept conversations, do not. WirelessIntercom systems with 900MHz and about 1000 meters to communicate.

2.4 units outside the market. There is a growing number of mobile phones and other devices in this series. As for intercom systems, video intercom systems are the main users of this series, although only wireless video intercom system on the market recently has been lost. 2.4 is the frequency used by data networks, WiFi (802.11b / g) in private homes and businesses so that the productsThis series may disturb others. However, neither the majority of people without problems in 2.4 systems do not mix. If there is a problem with an intercom system, may be that the gateway Wi-Fi is restarted when the intercom is used, or may produce a clicking sound at the intercom.

Setting the wireless router available information on the wireless router uses channels to communicate choices. If you have problems you can change channels gropedbut the problem is that many devices 2.4 spectrum of technologies that allow them to change their frequency every second or less dispersion. You can use the entire spectrum of 2.4, so that the frequency change can do something good. How wireless video intercom systems in this spectrum is available again and you have a wireless network, make sure that the intercom can return if it does not work for you.

Family Radio Service (462-467MHz) is the Ultra High Frequency (UHF) andbasically an improvement on the old walkie talkies of long ago. These portable radios are sold throughout the world and used heavily, so any intercom in this series will have to compete with this hand-radio (and everyone can hear your conversations). Not familiar with the wireless intercom systems that use FRS.

5.8GHz products are starting to make their appearance on the scene wireless phone. There are no compatibility issues between 5.8GHz and 2.4-drives, so no problemmust have experience in mixing them. But currently there is no wireless intercom systems in this series.

You will also receive a pair of intercom systems that claim to be wireless to see, but their real power wiring in your home or office user to send and receive messages transmitted through the intercom. This is often referred to as "FM wireless intercom systems, although the damage of house wiring in the AM band. To use them, simply connect an AC adapter into the wall. These systems are verytend to hum or buzz, and is not recommended unless you are willing to live with this possibility. Since entering the house wiring at 240 volts and is divided into two phases of 120, are also reported problems with trying to pass through the stages of experts. A part of your home or business can work well, where the other half not. These systems are typically less expensive intercom intercom system of the forest.

Long Range Wireless Intercom

The latest addition toWireless Intercom markets products in series Murs. MURS is a service in the VHF (Very High Frequency) 150 MHz Citizens Band radio. MURS has a power increase of four times that of FRS radios. And unlike FRS, you can create a larger or external antenna to be added to improve diversity. If you want to put an antenna on your house, you can do with Murs. Some antenna manufacturers claim an external antenna, effective radiated power from a transmitter by a factor of 4 increases. These Mursintercoms can transmit up to four miles, and perhaps more, with an external antenna.

E 'MURS wireless intercom system Interkom is that you need if you have a large estate, or need to talk through the buildings. You can create a Murs used not only to communicate in a house, but also the neighboring houses. You can also have a portable device for your MURS intercom, so you can stay in touch away from home.

Long Range Outdoor Wireless Intercom

Can alsocommercial-wireless phones, which communicate with two way radio and intercom base station. This wireless callboxes are waterproof and designed for outdoor use. That can open the doors or the doors remotely if you have a model with a port. Callboxes even in homes with anti-vandal stainless steel front panels. The extent of this is a task for a kilometer or more if you use an external antenna. This box wireless call can be battery powered with an AC-DC converter, orsolar. Callboxes is available in VHF and UHF frequencies, so you can customize to your current two-way radio that you had.

Wireless Intercom Features

Another thing to consider is what you need. Some systems have external intercom systems for use in the front door, or in other applications where a waterproof unit is necessary. A system also has a wire-wall-mount systems, so you can get your wireless system with a custom-installed system. You can mixWall-mount intercom with portable devices. It must also decide if privacy is important to you. If you do not want others to listen to your conversations, you must have a system that provides digital security.

So the wireless intercom system you choose depends on what program you have wireless devices is already in your home or office, the black, you must cover, as well as your budget. But when you select the right system, you will be able to enjoy the convenience of a wirelessintercom allows for next year.
