Audio and Video Door
Entry Intercom Systems provide secure, controlled access for visitors to
restricted door entry areas. The restricted area may be a floor of an office
block, a block of flats or a private residence.
The systems can range
from simple stand alone audio entry intercom systems comprising of a door
entry panel externally linked to an intercom telephone handset internally or
large multiple-tenant arrangements with a digital video door entry panel (or
number of panels for multiple entrances) externally, linked to multiple
video monitors and handsets in apartments or multiple office areas.
The larger systems
might also include a Concierge's switchboard arrangement so that visitors
can be dealt with by the building Porter during certain hours.
Audio Entry Systems
These systems are
audio intercom systems with a speaker and microphone built in to a special
panel which is usually located externally, adjacent to the entrance door.
The entrance panel will usually include a “call” buttons which visitors will
use to call the respective tenants or office areas directly over the audio
When a visitor arrives
at the entry panel, they must push the call button corresponding to the
tenant that they wish to see (assuming a multi-tenanted or multi office area
site), this will cause the respective telephone handset to emit an audible
'call' tone. The recipient of the call can lift the handset to talk to the
visitor and remotely release the entrance door (if desired) by the operation
of a remote door release push button, built in to the intercom handset.
The controlled door
would usually be fitted with an electrically operated locking device and
automatic door closing device so that, when the visitor has entered the
premises, the entrance door will automatically close and lock behind them.
Video Entry Systems
These systems are
basically the same as the audio intercom systems described above, but they
include video images. There is a camera built in to the entry panel and the
tenants' units will incorporate small monitors and handsets.
This means that the
central power supply equipment for the system is somewhat more sophisticated
to cater for the powering of the video camera and monitors. Also
consideration has to be given to the distribution of the video signal for
the numerous monitors on the system.
Telephone & IP Network
Intercom Systems There are some audio entry systems on the market which use
public telephone network or a Computer LAN/WAN IP based network for
providing entry facilities. These systems eliminate the need for the mass of
wiring that is usually associated with conventional telephone entry systems.
Voice Intercom systems provide voice communication between persons in
different rooms of a building where there
exists a need for quick and easy conversation. These systems provide
conference-type communication, connecting several intercom stations so that
persons can communicate with groups and sub-groups of other system users.
IP Network Intercom
Network Intercom systems are especially useful for buildings or complexes where there are
large numbers of tenants and can be expanded up to over 1000 of remote
handsets. These systems opens up a whole new range of possibilities, e.g.
providing remote access at multiple remote locations.
