Hybrid Solution Template
The security market is slowly migrating from analog CCTV to digital IP surveillance. However, a lot of investments were on analog devices before, and it is not easy to go totally IP and abandon the old analog devices when there is a need for expansion.

Migration to the Networked Enterprise
Security has usually been a local issue. It has become a broader issue, often global in character, requiring integration with a variety of support services. Digital video recording (DVR) technology is providing a level of functionality in physical security and surveillance applications previously unavailable. The basis for the new capabilities is quality digital pictures that can be easily distributed.

Digital Video Systems
This paper gives a general introduction to the composition, operation and benefits of a fully digital system, using the example of a CCTV application based on VideoBridge technology. In this context, a fully digital system is one where the transmission of video, audio and data takes place without the presence of a deedicated physical infrastructure connecting the camera to the monitor.

Image Resolution, Image compression and Frame Rate
Image Resolution - This is what enables you to identify people and objects. A high-resolution image looks sharp and images provide good evidence for identifying people and objects. A SVHS recorder, when new, gives about 400 TV lines of resolution and this matches the capabilities of typical colour CCTV cameras.
