Door
Entry Systems
With
these systems there is a basic choice of analogue or digital
available. These are used in housing environments, banking,
prisons, detention centres, leisure industry and general commercial
office situations.
The
external devices can be very simple in appearance using high
impact plastic laminates. They can equally use sophisticated
finishes such as brass or bronze or in extreme situations, stainless
steel. These finishes can be applied to both the audio and video
external units although they would be analogue or digital in
operation. In the case of simple audio systems, these are normally
controlled through a handset or a series of units throughout
the complex as with housing or on a one to one basis. A similar
situation would apply where video units are used and these can
be provided as purely monitors or monitors complete with handsets
dependant again on the operational environment.
Where these systems are used in highly serviced residential
environments, they can incorporate porter switchboards allowing
all calls to be screened by security staff before being relayed
to tenants.
