The objective of this course is to give you practical know-how in designing, installing, commissioning, maintaining and troubleshooting analog and digital CCTV systems. The poor quality of CCTV images often seen, doesn't inspire much confidence in the technology. However the purpose of this course is to ensure you apply best practice in all your work with CCTV systems. W ith the recent terrorist outrages in London and other cities, CCTV systems have been essential as a key tool in fighting crime. And have perhaps shifted from being part of "Big Brother" to a useful tool. CCTV systems have undergone a remarkable technology transformation in the past decade from analog to digital and in operating on a wireless or cabled network, with a host of additional features. This has made the design and maintenance considerably more complex.

This course thus provides you with useful expertise in building and maintaining a high quality CCTV system. The program commences with a detailed review of the fundamentals; progressing to optics and TV systems. Modern CCTV cameras and monitors are then examined followed by a review of video processing equipment and analog video recording. The vital changes from the analog to digital world are then examined in considerable depth. The essentials of networking as applied to CCTV systems are then discussed with practical examples. The course is concluded with best practice in CCTV system design and commissioning and maintenance.

How can an e-learning course be interactive?

Boredom can be a real danger, however, we use an interactive approach to our e-Learning – with live sessions instead of recordings.  The webinar software allows everyone to interact and involves participants in group work; including hands-on exercises with simulation software and remote laboratories where possible.  You can communicate with text messages, or live VoIP speech, or can even draw on the whiteboard during the sessions.
