Security systems
We provide installatin of a wide range of security systems, such as intruder/burglar alarms, fire alarms, CCTV systems, audio/video door entry systems, access controll systems.
Sensors are connected to a control unit via low-voltage wiring or a narrowband RF signal which is used to interact with a response device. The most common security sensors are used to indicate the opening of a door or window or detect motion via passive infrared (PIR).
New construction systems are predominately hardwired for economy. Retrofit installations often use wireless systems for a faster, more economical installation.
Some systems serve a single purpose of burglar or fire protection. Systems range from small, self-contained noisemakers, to complicated, multi-zoned systems.
Access controll system is a system which enables an authority to control access to areas and resources in a given physical facility or computer-based information system. An access control system, within the field of physical security, is generally seen as the second layer in the security of a physical structure.
CCTV is often used for surveillance in areas that may need monitoring such as banks, airports, stores. Surveillance of the public using CCTV is particularly common in the UK, where there are reportedly more cameras per person than in any other country in the world.
Intercom (intercommunication device), talkback or doorphone is a stand-alone electronic communications system intended for limited or private dialogue. Intercoms can be portable but are generally mounted permanently in buildings and vehicles.
