CCTV (Closed Circuit Television) is a visual surveillance technology designed for monitoring a variety of environments and activities. CCTV systems typically involve a fixed (or "dedicated") communications link between cameras and monitors.
The use of closed circuit television to detect crime and enhance public safety is increasingly recognised as an effective way to provide surveillance for your premises.
Portal321 specialises in providing CCTV systems which meet the requirements of a variety of property types, from retail premises to educational & industrial sites to offices.
CCTV can be simple or complex, for example to identify individuals or vehicles, to alert an operator to the presence of an individual or to visually patrol a pre-defined area. Once objectives have been agreed, an appropriate mix of system components can be recommended.
We can consult with you on a full range of cameras to suit all types of CCTV purposes, whether you need external pan and tilt cameras with weatherproof housings or a discrete dome camera for use internally.

In the past decade, the use of CCTV has grown to unprecedented levels. In Britain between 150 and 300 million pounds per year is now spent on a surveillance industry involving an estimated 300,000 cameras. Most towns and cities are moving to CCTV surveillance of public areas, housing estates, car parks and public facilities. Growth in the market is estimated at fifteen to twenty per cent annually.
The modern CCTV system involves a linked system of cameras with full pan, tilt, and zoom able to be operated remotely from a control room.
These systems may involve sophisticated technology. Features can include night vision, computer assisted operation, and motion detection facilities which allows the operator to instruct the system to go on red alert when anything moves in view of the cameras.
The clarity of the pictures is often excellent, with many systems being able to recognise a cigarette packet at a hundred metres. The systems can often work in pitch blackness, bringing images up to daylight level. |
