Cameras and Digital Recording

This is possibly the fastest growing area within the security industry and is directly linked to the evolution of technology.

One of the areas of great advancement is the Digital Video Recorder (DVR). These units have onboard processing for motion detection recording, alarm input recording and panic/duress recording (varied terminology).

A DVR can be linked to an existing PC network. This allows any PC monitor within that network to interface to the recorder via either a proprietary management program or through a Web browser. This allows viewing of live or recorded video and even the ability to extract and save a recorded event.

The DVR can be directly connected to a modem router with broadband connected or to a PC network with broadband connected. This allows viewing of live or recorded video and much more from anywhere in the world.

It is now commonplace for DVRs to have the capacity to record in real time (25 frames per second). In addition the cost of a hard disc drive (HDD) is reducing all the time. This then allows the DVR to have larger onboard HDDs thereby increasing the archiving capacity dramatically.

The capability of CCTV cameras has also improved enormously over the last few years especially in the areas of resolution of an image and also in the variety of cameras and lenses which are now available.

Clients now have the choice of full body, dome, bullet, pressurized housing, infra red and now mega pixel cameras, depending on the application required.

Cameras with the appropriate lenses have the capability to produce a high resolution image in good light, low light, bright light and in total darkness.
