Wireless Intercom Review
Hosmart FM Wireless Intercom
This wireless intercom has some nice features stated such as voice activation
(VOX), monitor mode, digital security, and multiple channels. It uses the very
popular Family Radio Service frequencies. So while they are transmitting
digitally, and you should not hear conversations from other radios, if someone
is using that frequency near you there could be some interference. We
experienced buzzing noises while testing the Monitor mode.
The best feature on this intercom is the channel feature. There are 6
channels and you can set the default channel on each intercom so that if a user leaves their channel to talk to someone else, it will default back to it's
This button enables you to call all stations no matter what channel they are
The monitor mode is used to listen for "noises" in another room. The audio
quality is quite poor so unless someone is sitting right in front of the
intercom you won't likely be able to understand what is being said.
Voice Activation (VOX)
By holding down the Monitor button for a few seconds the unit will go in to
voice activation mode. I allows you to just speak to transmit. However, like the
Monitor mode, if you aren't sitting right in front of the unit the receiving
party will not likely understand you. Also, like all units with VOX, the first
word you speak will not be transmitted since it takes some time for the
microphone to turn on. Loud noises will also activate the microphone.
If you just want a very low-cost, basic intercom with multiple channels and
are not concerned with the Monitor or VOX function, then this system may work
well for you. It has fairly good audio quality as long as you are right in front
of it when you transmit and does get very loud, but the audio does distort at
It says it gets 1500 feet of range but keep in mind that this is with nothing
between the two points so you will get less distance than that. Also it seems
prone to electrical interference so it may be more suited as a home environment.

Factors to Consider in Choosing a Wireless Intercom
When you see claims about distance for a wireless intercom, that claim is
almost always the best possible scenario. Which means the range is
point-to-point, line-of-sight with nothing in between the two points; no walls,
no trees, no vehicles, no anything.
With commercial-grade equipment like we carry there are way to get the
maximum range or even more. For instance with our two-way radio based intercoms
the antenna that come with the unit remove and then you can attach an extension
cable that allows you to place the antenna somewhere where walls and other
obstructions are no longer a problem. You can even place them on tall masts and
the higher you go, the further the distance you can achieve. We also have
digital intercoms that have removable antennas that enable you to do the same
In the case of a WiFi intercom, there are simple WiFi extender antennas that
enable you to plug the extender into your wireless router and place an an
antenna outside. With these you can extend your wireless Internet to distances
as much as a mile in ideal circumstances. When someone presses the button on the
intercom, it calls any landline telephone or mobile phone you want so it doesn't
matter where you are.
Then there are cell phone based intercoms that don't have any range
limitations at all. As long as you have a good cell phone signal where you want
to install the intercom, then it doesn't matter how far that intercom is away
from the location you want to talk to. Like the WiFi intercoms you can be
anywhere in the world and still talk to the intercom.
The other factor to consider is durability. In commercial applications, or
anytime an intercom is used outdoors, durability matters. If you're budget is
limited to only a couple of hundred dollars just keep in mind that corners had
to be cut somewhere to get the cost down that low. Any intercom that is used
outside needs to be in a weatherproof housing. That need by itself increases the
cost of the system.
In industrial or business-type applications there is typically a lot more
usage of a system and employees don't treat property as gently as someone in a
residence would. Neither do customers so keep the usage in mind when choosing a
There are wireless systems like our MURS products that have the ability to
expand virtually unlimited. There are indoor and outdoor intercoms, long-rang
wireless PA speakers, switch activated recorded message transmission devices,
customer service callboxes, motion or metal detecting sensors, and other devices
that can be part of the same system.
For specialized applications this flexibility can often solve whatever
communication problem you have.
