What is Digital CCTV?

Digital CCTV, or Digital Closed Circuit Television, is the technology rapidly replacing traditional VCR. In the old VCR system, CCTV pictures are sent via the CCTV camera to a closed area, e.g. a CCTV Monitor. This type of CCTV is likely to produce lower resolution images and to rely on unsightly and inconvenient cabling.. Modern Digital CCTV Systems can be operated remotely using a laptop or mobile, can cover various locations, and be viewed from anywhere providing internet access or a mobile signal is present.

Advantages of Digital CCTV

The benefits of using a digital system, is that it uses a smaller quantity of equipment and the user does not have to keep changing video tapes as everything is automated. These systems can record video images on the HDD or onto a remote computer - this latter has both capacity and security advantages. A digital system means the database can be searched by camera, time, date, alarm-activation or motion. This saves the user much time.

In addition images are more focused and detailed and can be repeatedly viewed without loss of quality.

So the basic advantages are:

• Less storage space required
• Archiving is possible
• Data More Easily Accessed
• Higher image quality
• No Tapes
• Less affected by noise -
• Transmit and retrieve stored data
• Less Obsolescence
• No Routine Maintenance Required
