Real Estate Agents Use Wireless Intercom for Spec Homes

When a large, residential housing development is under construction there are usually several inventory homes available for house hunters to look at. Quite typically there will be one real estate agent handling the open houses in all of these homes. Obviously the agent cannot be in all these new homes at once. That’s where a long-range wireless intercom system can help.

When a visitor enters a spec home they will see a wireless intercom base station in the foyer or kitchen with a sign that says something like, “Please press the Talk button for assistance”. Each inventory home will have one of these wireless intercoms in it.

The real estate agent will have a handheld intercom that talks with these base station intercoms. Since these wireless intercoms have a range of up to four miles, they should work well for even the largest new home construction subdivisions.

The MURS Multi-Mile Intercom at IntercomsOnline has all the capabilities needed to service inventory homes in new residential developments. Watch the video below for more information.

Wireless Intercoms For Monitoring Other Side Of Bulletproof Glass

This customer wanted wireless intercoms to place on the outside of bulletproof glass so they can talk to people on the other side. We recommended the WireFree Wireless Intercoms for this application.

The WireFree system has a VOX mode that enables you to press the Talk button on the inside intercom and then the person on the other side of the bulletproof glass can speak without pressing a button. They just simply speak and you hear them (there is a two second delay before the microphone is activated). You can interrupt them at any time by pressing your Talk button so you remain in control of the conversation. They can speak for up to 15 seconds before the microphone cuts off again. You can simply press the Talk button again for another 15 seconds (both units must also be set in Conference mode as well).

There is a Monitor mode on the WireFree system that you could activate so the microphone on the listening end is always activated. You will then hear everything that occurs on the monitored intercom. If you want to talk, you have to press the Talk button on your intercom. Both intercoms should be powered by AC to DC power supplies since batteries will be quickly drained.

Calling Individual Rooms With Wireless Intercoms

Many of our customers want to use wireless intercoms to call individual rooms in their home or business without calling all the other rooms. Unfortunately, wireless intercoms are not the best at this application, but there is a way to do it. Generally, a telephone system is the best at this application.

Our WireFree Intercom System has four channels and each room could be set to a different channel. If you have a main intercom, it can be set to monitor all four channels so the rooms can call it. When the main intercom responds, a private conversation occurs. If the main room needs to call one of the rooms, you would press the Channel button to match the channel of that room. At the end of the call, you would put the intercom back in the monitor all channels mode by pressing the Channel button until all four channel lights are on.

The MURS Multi-Mile intercom has 5 channels, but it does not have the ability to monitor all 5 channels at once.

900MHz Wireless Intercom Interfer With Wireless Network?

We quite often get asked whether our wireless intercoms will interfere with a wireless computer network. Neither of the two wireless audio intercoms we carry are in the same frequency as a PC network. Wireless home PC networks operate in the 2.4GHz range.

Our 900MHz Wireless Intercom is in not only in a different frequency, but it also uses spread spectrum, which means that it jumps across multiple frequencies in the 900MHz range.

We also have MURS radios that communicate in the 150MHz frequency. These intercoms and radios will also not interfere with a PC network.

So you won’t have to worry about your PC wireless network when using wireless intercoms.

Home to Garage Wireless Intercom

We get lots of calls from wives who are tired of yelling out to the garage or workshop to talk to their husbands. They want a wireless intercom to stop the yelling.

The proper wireless intercom depends on the house. The ranges listed by the manufacturers are clear, line-of-site ranges. If there are any obstructions at all between intercoms, range will be reduced. The materials between them also affect range.

Brick walls reduce range more than drywall does. Metal-framed walls reduce range more than wood-framed walls. Even electrical wires in a wall can reduce range. It’s a bit of black magic so you can never say for sure what wireless intercom is right for you.

If your garage is attached to the house, then our WireFree Portable Wireless Intercom System (set of 2) will likely work for you. If your house and garage are a long ways apart from each other, or the garage is metal-sided, then the MURS Multi-Mile Intercom is a better choice. Go to www.intercomsonline.com for more information.

MURS Radio

A MURS radio operates in the 150MHz frequency. You can now buy intercoms that will communicate with two-way radios that operate in the MURS frequency. At IntercomsOnline.com we carry MURS two-way radios, intercoms, outdoor callboxes, and even wireless public address (PA) systems.

Our customers are using these MURS devices together in lots of interesting ways. One is that you can set up a PA horn in areas of your business and set it so it is on a separate channel from your radios. If you want to page someone you just change to that channel on your intercom or radio.

The outdoor call box can be used at outside locations so people can call you when you are on your MURS radio.

You can find these MURS devices on the Commercial Intercoms section of www.IntercomsOnline.com.

Commercial Intercom Systems

Most businesses who call us have a need for a wireless commercial intercom of some type. The reasons for wireless versus a wired system almost always have to do with the high cost of running wires. The high cost of hiring an electrician to run wires almost always warrants the cost of a industrial intercom type of system. We have several products that use a newly assigned MURS business frequency. This frequency allows long distance transmission and is usually powerful enough to overcome interference caused by equipment found in an industrial or office environment. It can also overcome challenges that result from commercial building construction.

Below is a video on how to buy a commercial intercom system.

Long-Range Wireless Driveway Alarms For Long Driveways

A customer had a driveway that was about one mile long and they wanted to be alerted when someone was coming down the driveway. They did not want to run a wire that far so they wanted a wireless solution.

The MURS Alert Kit had all the features they wanted and more. It is a long range wireless driveway alarm that consists of a wireless intercom and a wireless motion sensor. It is capable of up to a four mile range. When someone is coming down the driveway, the motion sensor sends a verbal “Alert Zone One” message to the wireless intercom. They can have multiple wireless intercoms in their house. They can also use these intercoms as intercoms for internal communication.

There is even a handheld two-way radio that works with this system so they can be roaming around their property and still know when someone is coming down the driveway.

There are two sensors available, one probe sensor that gets buried along the driveway and only goes off when it detects metal. The other detects motion.
