The ubiquitous Router is the workhorse of the Internet. Some estimates put the global total at over 12 million. But exactly what do they do, and how do they do it? This Bite Size Module provides the answers to these and other questions. In this Bite Size Module, we’ll examine the development of the router, from a simple packet switch, to the highly intelligent device we have today.   The fundamentals of a routing protocol Queuing and priority Autonomous Systems Read more

This Video Content Analysis (VCA) course is designed for integrators, installers, specifiers and end users who are considering utilising VCA technology in their video surveillance system projects  Video Content Analysis (VCA) is the process whereby CCTV images are automatically integrated for a particular situation: such as the detection of intruders, people counting, smoke detection or any other situation that can be both seen and accurately defined on a video image, so an alert can be raised. New VCA systems have a wide range of applications and use specialist cameras and VCA tools which can be used to increase the effectiveness and return on investment of CCTV systems by adding enhanced or increased capabilities to detect events and analyse post-event video.   Read more

The commissioning process will verify that a newly-installed system meets both the technical performance of the selected equipment and the operational requirements set out in the early stages of the design process. It is important to review the original design specification and operational requirements prior to writing a commissioning plan. A commissioning plan lays out a step-by-step guide for commissioning a system. It details roles and responsibilities as well as defining the commissioning tasks and a timeline for carrying them out.
