This phone system will allow you to write a wise choice when selecting a wireless intercom system. Only a limited number of wireless intercom systems on the market, such as the selection is not as difficult as choosing other types of consumer products. There are only three wireless intercom systems available.
Power Line Carrier Intercom
Portable PA Systems
The wireless intercom system is not really wireless. Sending and receiving electrical cables through the house.Westinghouse is one of them. Radio Shack has one too, but please call (FM) FM intercom (I suspect it marks the Westinghouse Intercom Radio Shack, the product itself). It sends and receives on FM frequencies, but it is more than power lines.
These systems power line carrier that work well, but it frustrates more than half of those who use it. A problem with these systems the way the house is wired. If220 volts coming into the house, and 220 in two phases, 110 V is divided, half the national scene and the other half is fixed. The problem is that the FM signal is generally not to jump on stage, or if it is not very good. So nice to be able to bypass the center of the system from home, you're not wrong, the other half.
The other problem is that Power-Line Carrier communication systems can be connected to devicesInterference in the FM signal. Microwaves can be one of the worst. These intercom devices unusable. Although these communication systems are cheap and you can try that if you work at home is not recommended for commercial environments. There are only two of many devices in an office environment or industry they are unusable.
900MHz Wireless Intercom
The second line of the free market is 900 MHz Wireless Intercom. Sinceits name suggests, allows wireless users to a range of 900 MHz. It is the only true wireless system on the market. This is not the only one that has wireless in the ether, but the only element. Unable to communicate not only with the wiring of your home or business is not plugged in when you choose to purchase power adapter.
The wireless system is due to various cost elements that have no other singleWireless Intercom. Intercom system is portable, surface to sit on the surface S. a table, desk, there are two ways this place called the end of the wireless system. It sends and receives the same street as the field device are not extreme. As the maximum distance of 1,000 meters, but it is likely that the range of 300 meters depending on the context. Both devices have the same properties.
The wireless system is impervious to wateroutside bell, intercom, which can be used outside of the door to talk to people. The beauty of the device, when people press the button on the door, then a speaker.
There is also a waterproof outer door that can be used in any outdoor installation. This requires the intercom button for each transmission. Then the hanging wall or put rubber feet on the machine, and it turns out, if you want. The good thing is that there is greaterButton, easy to use.
The wireless phone system also has its own search system user-defined constructs. You need a hole in the wall, but the battery, so no wiring is required. The autonomy of each wireless device 1 and 2 years, so you do not need many items.
The system provides wireless and VOX control that all mobile phones. The monitor mode is like a baby monitor. The differencenot control all the time. Only when the microphone, loud enough to the microphone in the series. Three different sensitivity to activate the microphone, but also the most sensitive, it does not appear for the poor, more than half a meter from the microphone as well. The back of the monitor mode for certain applications, the voice on the receiving end every time the microphone for sound. When usedThe monitoring of these children, it is unfortunate that rather quickly.
If you attach a VOX device free, when someone from another unit, the unit can respond to requests for VOX hands-free without pressing the Talk button. The problem is that radio, VOX, which means that there is a slight delay in transferring the VOX distributor passes the microphone to handle. Experienced users know how to overcome it, repeated the first word or two, butfor the layman, this period is a bit "boring.
A unique feature of the ability of a Wi-Fi system, private interviews. The units must be "taught" to speak to each other. If this is done, even if the neighbors of the same device, not hear or talk to you. Even if a page is broadcast to all units, the system responds to a wireless set up a private conversation between the sender and the person that you do not want to hear the other units,Conversation.
Walls wireless intercom
Also a wireless intercom system is not the computer manufacturer, for a number of wireless intercom and radio systems. This "system" is a high frequency products that are compatible with the Walls. Report walls and Multi-Purpose Radio Service two-way radio service consisting of five frequencies in the VHF (Very High Frequency) spectrum. Unlike most of the VHF frequencies in the walls do not require FCCThe operating license.
Although only 5 channels, each channel between the 38 "soft-code" or sub-channels, you select that you do not hear calls from other users in this channel. Call the same channel and code of the radio quiet . In most areas, the frequencies used very few walls, you can not find much competition on the radio.
The biggest advantage of the area, Walls offer. Some manufacturersYou are entitled to a range of four miles. Of course, this is the path of sight, no obstructions between the intercom systems. In the field of communication systems and high-gain external antenna for your home, business or car if you are using a device should be increased.
Walls The beauty that you get a radio station, vehicles and communications systems outside the base station / console, and the movement that the verbal warning to other devices Walls. ToCommercial, industrial and commercial applications with wall systems because they can overcome many problems and obstacles of these applications.
If you need) a system of wireless PA (Public Address, PA is a wireless connection with all the walls. The retail and services directly to customers, a wireless device for the customer to push a button and Walls ask for help via a recorded message.
SinceWalls wireless device manufacturers, the choice of system from the inside walls must be independent of a particular manufacturer's products.
Regardless of whether the wireless phone system you choose, comfort and security to offer fast and installed without problems.
