Closed Circuit Television (CCTV)
Visual surveillance is a very effective tool for combating risk. Cameras work in ‘real time’ and linked to control mechanisms and recording devices,
they reduce risk and manning requirements, whilst appreciably improving general security.
Astec provide colour and monochrome systems for internal and external use for a full range of environments and light levels.
Remotely controlled cameras pan tilt and zoom, manually displaying selected events or general views.
Images are integrated with graphic maps that show locations and switch cameras as an operator tracks through a site.

Digital Video
Digital video converts images into computer files giving CCTV systems the high level of flexibility associated with IT systems.
Recordings are made to a database that can be sorted and images retrieved at very high speed and related very closely to specific events.
Through the lens motion detection, provides pre-alarm images that show the operator what happened prior to the alarm event.
This is a very powerful new technology that is revolutionising the way CCTV is used. Ethernet networks,
Internet and WAN are utilised to allow viewing of images from multiple and remote locations, revolutionising the flexibility of managing CCTV.

Remote Video Monitoring
Digital images are transmitted from CCTV sites to a Video Central Station that remotely manages the CCTV, access control and alarm systems.
This provides reduced operating costs by reducing manned guarding costs. It also manifestly improves the security of unmanned sites.
A speech link to the site allows operators to warn possible felons that they are being observed, making the system pre-emptive and thereby reducing incidents.
