Access Control Systems
We install and maintain Access Control Systems and Door Entry Systems for commercial premises and residences.
Access Control Systems can provide a convenient and cost effective means of restricting access to callers who have been identified and/or to authorised users. The design of the system must take into account the type of use which can be expected and the level of security required. The system must be practical and easy to use and care must be taken to ensure that accidental lock-outs cannot occur and that the system does not impede exit from the premises in the event of a fire or emergency evacuation.
Door Entry Systems provide an intercom between the outside unit and a handset. Handsets can be incorporated in different areas such as individual flats. A door release can be included which can allow the caller to be admitted at the push of a button. Video Door Entry Systems include a camera in the outside unit and monitors incorporated in the handset.
Digital Code Systems can simply release the locking device when the correct code is entered. They can also be an integral part of a Door Entry System to allow authorised users access.
Proximity Systems provide a higher level of security. Authorised users can gain access using a card or a fob which can be 'voided' in order to bar access to a specific user. Again, an intercom system with or without C.C.T.V. can be incorporated for visitors if appropriate. Magnetic cards are like credit cards and have to be passed through a slot in the reader. Proximity cards or fobs are passed close to the reader and with the fobs being extremely durable and passive (no batteries) the additional outlay can prove worthwile in the long run.
Card and proximity systems can be enhanced with the introduction of a P.C. which can be used for programming, validating, voiding and recording use of cards or fobs to gain access through specific doors logging date and time etc. A system incorporating a P.C. can provide an easy solution where a large number of doors or users is specified.
