Monitoring of the system may be by dialer for contact with key-holders or to an alarm receiving centre using either a digital communicator, a monitored telephone technique such as RedCARE or with dual path signalling using a combination of telephone line and Cellular (GSM.) Cameras are specified to be external or internal, fixed or pan, tilt & Zoom (PTZ). Cameras may be clearly seen to act as a deterrent or discreet thereby maintaining a low profile security for visitors and staff. Access Control may be used in a range of applications from controlling a single door to controlling multiple doors connected to a computer system on-line, designed in a modular format so that your security can grow with your organisation or your needs.
