Intercoms Audio and video door intercom systems are ideal in situations where visitors are regular and their identity cannot be verified locally. One of the places where Leigh Visual have installed many of theses types of handsets is in hospitals, where access to wards late at night can often pose a threat to staff. The two main types of door entry systems are video and audio. Both of these systems grant access to a remote door. As
with single door access control solutions door entry systems can use the
same types of locking mechanisms. Door entry systems can also be used
in multiple locations, this is particularly useful in multiple occupancy
environments such as a block of flats. Modern systems allow for communication
between entrance stations and landline or mobile phones. This can be particularly
useful in situations where access may need to be granted remotely.
