Telguard Access Control
The Telguard product range consists of variations of the same concept. The concept is that all Telguard products communicate to the call destination via the telephone network to telephone apparatus.
This may be through a wired link to a dedicated BT type telephone socket, an analogue extension socket of a telephone system or wireless via a SIM card through the mobile phone network. Alternatively using wireless DECT (digitally enhanced cordless telecommunications) technology.
