available for an intercom system really depend on what system you are looking at
and what you are trying to accomplish. Wired systems have different capabilities
than wireless systems.
Below are a few features you'll find on our intercom systems:
Call Individual Rooms: This is something wired systems are
better at doing.
Wireless intercom systems broadcast to all stations. The only way you can
call individual rooms is if all systems are set to different channels (there are
typically 4-5 channels). The problem with this is that if someone changes the
channel to talk to you on your channel, but then doesn't change back, how will
you know where to call them? If everyone is on the same channel, they hear
everything being said. The one exception to this is the
UWS Wirefree Wireless Intercom
which sets up a private conversation when
someone responds back to the initial page.
Handsfree: This feature enables you to press a button, let go, and then talk to a person at another station without having to hold a button down.
Most available intercoms don't do this all that well. Some wired
systems have the ability to put a substation in monitor mode so you can
constantly hear what's being said and then you just have to press a button to
talk to them. The
UWS WireFree Doorbell and Intercom has the handsfree ability at the door.
The UWS WireFree inside units have voice activation capability but the first
couple of seconds of response is clipped off while the microphone is turning on.
If you need this feature, you may be better off going with a telephone system
Expandable Recording Color Video Intercom System is a video intercom that has a built-in live video
recording function that provides a date and time stamp to show you who was at your door even when you are not home.
You can pop out the its memory cartridge and copy the video to your
computer. It's a little bit like a security camera attached to a digital video recorder.
Video Monitor: This feature allows you to
monitor anything around the door phone camera. You'll press a
Monitor button and the camera will activate without alerting anyone
by the camera. Using this feature you can check on the kids playing
in the yard, check so see who is at the front door even if they
don't press the call button on your door phone, or observe the area
if you suspect vandalism or some other crime. Most video intercoms
have this capability.
Electric Door or Gate Opener: If you add an
optional electric door opener to a door intercom or wireless callbox,
some systems will let you press a button to unlock the door
MURS Callbox XT Outdoor Intercom with Gate Relay
has this capability.
Long Range Wireless Intercom: The MURS
long range wireless intercoms have the ability to work at ranges of a mile
or more. There are a wide variety of MURS devices that meet lots of different
Digital Privacy Wireless Intercom: The UWS WireFree system had digital
privacy so you conversations remain secure.
Use Existing Telephones: The
DoorBell Fon DP-28WT Doorbell Intercom System
lets you use your
existing telephones to respond to visitors at your door, and you can even unlock
the door provided you have a an electric door lock installed.
