Q: I want a voice only wireless intercom, but I don't
know whether to choose the MURS Multi-Mile or the WireFree
intercom system. Which one should I choose?
A: It first comes
down to range. If you need less than 1000 feet, pick the
WireFree. It is cheaper and it provides digital security
whereas the MURS does not. The MURS does have privacy codes
so you won't hear other people on your channel, unless they
are set to the same privacy code (38 available). The
Wirefree system also can be run totally battery powered and
it has an outdoor intercom
available for future expansions. The MURS system does have
wireless outdoor intercom call boxes, but they are more
industrial looking and much more expensive. If you are concerned about
range, then the MURS has the longest range of any wireless
intercom system on the market. It is also on a wireless
frequency that doesn't have much traffic.
Q: Do walls and
other obstructions limit the ranges specified for the
A: Yes. The
ranges specified are for the most part clear line of site
ranges. So if you are in a Kansas wheat field with no
obstructions between wireless intercom units, you should
easily get the range listed. However, when you have walls in
the way, range will go down. Brick walls reduce range more
than drywall does. Metal-framed walls reduce range more than
wood-framed walls. A wall filled with electrical wires every
foot or so will reduce range more than one with only one or
two wires in it. There is no magic way to determine whether
a wireless intercom will work in your application so you
just need to try it and return it if it doesn't.
Q. We have a
workshop that is a metal building in our backyard, which
wireless intercom will work in it?
A. The WireFree
intercom system most likely isn't strong enough to make it though the
walls of the building into the house. The better choice for
this application is the high-powered MURS Multi-Mile base intercom. The MURS Multi-Mile intercoms
have the power to punch through both the metal walls of the
building plus brick walls of a house. The range will be
significantly less than four miles, but for most
applications they should still work. We do have a 45-day
full-purchase price return policy if they don't.
Q: Will your
intercoms interfere with my wireless network for my
A: Wireless home
PC networks operate in the 2.4GHz range. Our voice only
wireless intercoms operate in other frequencies so they
Q: I provide
caregiving services for my elderly parent an I'm looking for
a wireless intercom I can use to talk to them. What do you
A: That depends
on the capabilities of your parent. If your parent is not
capable of pressing a button, then you would need the UWS
WireFree Portable intercom which can be put into Monitor
mode (we recommend you use AC power in this mode.). In
Monitor mode the intercom in their room will transmit audio continuously. You will need to ensure that the unit is
as close to where they will be sitting/laying as possible.
If your parent can press a button, then you can use the
UWS WireFree Portable intercoms in normal mode. But the
WireFree Portable has multiple buttons and your parent could
accidentally change the channel your intercom would not
communicate with theirs. If you want to ensure that this
doesn't happen, either the UWS WireFree Outdoor intercom or
the UWS WireFree Doorbell Intercom could be used. These
intercoms only have one large button so there is no way they
can change the channel. All they can do is press the button
to call you. the WireFree Doorbell intercom lets them press
the button once and a tone sounds on your intercom and they
can speak instantly. They don't have to press a button again
to talk. The downside of this intercom is you can't call
them until they press their button. With the WireFree
Outdoor intercom they have to press a button every time they
want to talk. But you can call them anytime you like.
Q: I need a
wireless intercom that can call from one main room to four
different rooms individually
. Do you have a wireless
intercom that will do this?
A: The WireFree
Intercom System has four channels and each room could be set
to a different channel. The main intercom 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 wireless intercom has 5 channels, but
it does not have the ability to monitor all 5 channels at
once. However the MURS Commercial Base intercom does have
the scan all channel mode.
Q: I need a
wireless door intercom for my front door and a wireless
intercom inside my house. What system do you recommend?
A: Our WireFree
Wireless Outdoor Intercom will work for this. They come in
sets of two so you could use the second one inside the
house. You can also pair these with the WireFree indoor
portable units. We also have the WireFree Doorbell and
Intercom kit that comes with one outside unit and one
Portable intercom. See the product descriptions for the
differences between the two options.
Q: I need an
intercom in a commercial building. Should I go with wireless
A: A wired system
would likely provide the most reliable service, but it
depends on your building. In most cases a commercial
wireless system will do fine. But the more concrete and
electrical equipment you have, the higher the chance that
the wireless system won't work for you. If you can afford
the expense of running the wiring, then you know the system
will work. We do have a 45-day return policy, so if you want
to try wireless, you have nothing to risk except shipping
costs. If you go wireless, use the license-free MURS
Wireless System or pick a UHF system that needs an FCC
license to operate.
Q: I need an
intercom in a room in our business that will allow me to
call into that room to see if someone is there, and if
someone is in that room they need to be able to respond
without pressing a button. Will the WireFree intercom
A: Yes, it has a
VOX (voice activation) mode that lets someone respond to a
page from another intercom without having to press a button.
They will need to speak loudly to activate the microphone
and there is an approximate one second delay before the
microphone is activated so the first part of the response
could be clipped. As an example, if the user says, "Yes, I
am here." The "yes" may not be heard.
Q: For the
WireFree Intercom System or the MURS system, is there one master base station
and then separate slave sub-stations?
A: No, all the
stations are the same. All the units are exactly the same unit
whether you buy a set of two, or you add on a single unit.
You can mix these units anyway you like.
