Lighting, of whatever type is essential to produce CCTV (VSS) images of evidential quality, this bitesize module with audio delivered by one of our expert tutors will look at light & CCTV including the behaviour of light, light meters and the different types of light. Read More

This Bite Size module takes a fascinating look at Local Area NetworksAn obvious question to ask is 'is it a network?'  That of course depends on your own definition of the word 'network' However, if the analogy of a road or rail network is used, you will see that a LAN, for example, is not actually a network at all. A road network provides alternative routes between geographic points, which are instantly available to a traveller. The same goes for the rail network. Read More

Following on from LAN bundle 1, this bundle explores Virtual Local Area Networks (VLANs), why they’re needed, how they are set up and used, and how Quality of Service over Ethernet became a reality. We explain how the Domain Name Service (DNS) swaps web and email addresses into the correct IP addresses and also the principles behind providing Quality of Service. You’ll learn about delay, jitter and loss, presented in an easily digestible and jargon-free manner. Lastly, we examine the development of the router; from a simple packet switch, to the highly intelligent device we have today and the fundamentals of a routing protocol, queuing and priority, and autonomous systems. On completion of the four bitesize courses, you will be able to download and print a certificate to demonstrate your learning which is also worth 8 CPD (Continuing Professional Development) points.

This bundle of four bitesize learning modules takes a fascinating look at LANs ( Local Area Networks) and the relationship between bit rate and bandwidth. You’ll learn how cabled networks and broadband supports high data rates, together with their impact on CCTV quality. We also take a look at the most popular types of UTP cable and their connectors, and explore the range of simple tools and utilities which are available to trace faults, determine end-to-end delay and pinpoint problems in IP networks. On completion of the 4 bitesize courses you will be able to download and print a certificate to demonstrate your learning which is worth 8 CPD (Continuing Professional Development) points. Read More

Locking mechanisms and turnstiles play a pivotal role in access control. Within this course we provide an introduction to the wide variety of electronic locks available , including maglocks, as well as  cover different types of vehicle barrier systems and turnstiles. We also simplify the difference between Fail Secure and Fail Unsecure locks. Read More

In this Network Infrastructure bitesize bundle we look at IPv4 - which is still in widespread use today. You’ll learn about IPv4 in private networks, including CCTV, and how IPv4 works. The bundle covers masking, moving onto the better-known IPv6 as used in public networks, such as those provided by ISPs and carriers such as BT, perfect for those with an interest in IP addressing in general. We take a look at how the current 4th and 5th generation mobile networks have evolved, and how faster speeds have been achieved before moving on to Light Fidelity (Li Fi) communication technology (using light to transmit data). Li-Fi - is the latest and possibly the most exciting alternative to Wi-Fi and mobile networks. These jargon-free short courses are aimed at anyone with an interest in how these interesting technologies work, and with an interest in IP addressing in general. On completion of the four bitesize courses, you will be able to download and print a certificate to demonstrate your learning which is also worth 8 CPD (Continuing Professional Development) points.
