Glossary > Security Systems

The security of a building and the safety of the people living and working within it are of the utmost importance to any organisation. Our range of security systems offer the latest innovations in access control, CCTV, and door entry technology, including:

Keypad - Access through doors is by means of a digital keypad and electric lock release. The use of a separate controller ensures that no amount of tampering with the keypad will undermine the system's security. For convenience the system is programmed from the keypad and offers a wide range of useful functions.

Proximity detection – Entrance is gained into the building using a pre-coded keyfob device which is simply presented to within 10cm of the control plate for the reader to access the stored code and open door. The keyfobs are easily programmed onto / deleted off the system, and the lack of moving parts provides greater security against vandalism.

Magnetic swipe – The core of our magnetic swipe card business is with hotel door access, we install an integrated magnetic card reader and electronic mortice lock unit onto a hotel room door. A swipe card programmer is located in reception, the receptionist programes the card, using a magnetic strip, to the specific room, the room lock then identifies the card using a magnetic reader. This system provides a lot of value as the cards are very cheap to replace if lost.

Smartcard – A similar model to the magnetic swipe card but with this system the information is stored on a microchip embedded within the card. Smartcards are slightly more expensive than magnetic swipe but the cards are less liable to have their code corrupted during extensive use.

Biometrics – The cutting edge of access control, this technology uses fingerprint analysis to gain access to a room or building.

Cameras – The decision as to which type of camera to use depends on its location environment and the type of subject being monitored:

Mono – Best suited to poor light conditions, enabling increased image definition. Colour – Best suited to good light conditions (daytime or indoor) where image clarity is important. Lenses – There are a wide variety of lenses to choose from with wide angle and zoom capability for distant objects or wide views. Cameras – There are Dome, Covert, Fixed, - Pan, Tilt & Zoom (PTZ), all have their particular uses for specific situations.

Control Systems – Known as multiplexers and matrix units, this equipment combines the input from several cameras to provide individual or multiple viewing. In the case of motorized Pan, Tilt and Zoom cameras, the equipment enables the operator to control the camera while viewing the monitor.

Recorders – This device provides evidence of when and where an incident occurred and what has actually happened. There are a wide variety of products which can record the information but they are split into two main types – cassette tape recorders using analogue storage and digital video recorders which use a hard drive similar to those found in personal computers.

Monitors – A monitor display’s the views from a range of cameras and are specific to CCTV installations. They range from low resolution mono to high resolution colour.

Audio Door Entry – Often considered to be the “low cost” option, our audio door entry system is by no means poor quality or unreliable, we prefer to call it the “good value” option. The audio system consists of an entrance panel which allows visitors to call a resident and be identified audibly via the intercom. The resident receives the call though a handset which has the facility of unlocking the main entrance door. Residents can gain access to the building using a master key, a keycode on the entrance panel or a proximity key, often called a keyfob. If the keypad code is compromised or a proximity key is lost, it is easy for a nominated person to update the system. Diagram of Audio door entry system

Video Door Entry – This system offers a higher level of security than the audio system, as the resident is able to see and talk to the callers before opening the door. In this case the entrance panel has a small high resolution camera placed behind a protective glass shield. The audio and video signals are then received by the resident through a telephone handset, in real time, with a mono or colour LCD display. Once the caller is visually identified the door can be opened by pressing a button on the handset.

We use only the highest quality products for our security services and all installations are carried out to standards set by the British Security Industry Association.
