Professional Practices of Security Network Design (BTEC Level 5 Certificate)

This Professional Practices of Security Network Design is the ideal course for those looking to develop a deep understanding of IP & Networking issues.

This tutor supported course is intended for people with little or no knowledge of computers or IP networks. It  is packed with the essential knowledge needed to design, plan and build effective fully operational IP based security solutions and most importantly learning about the pitfalls to avoid.

Over twelve fascinating modules you will cover the fundamentals of digital cameras, local area networks and IP. Each module is supported by Self Assessment Questions designed to check your learning progress, and at specific points in the course there are four detailed Assessments and Projects.


Study Times and Entry Requirements
The Security Network Design course contains 12 modules, each requiring approximately 20 hours of study. There are no prerequisites and no qualifications needed to enrol.

Course Cost: £995 inc VAT

Recommended Duration: 240 hours
Includes: BTEC Level 5 Certificate

Course Content

Module 1. Introduction and Standards
The first module provides an introduction to the course, and explains how to use and navigate the system, its interactive features including the audio tutor, video, the glossary, ‘hot spots’ and other benefits before moving onto the role of standards. The main standards bodies which impact on IP networks and CCTV systems are introduced, from IEEE to ANSI, and ONVIF to the IETF, and their importance is explained.

Module 2. Bandwidth and Storage
This module introduces the concepts behind the digital CCTV camera, and explains how the image is produced. The concepts of bits and pixels, together with the binary concepts which underpin image production are fully explained. The module then goes on to explain the need for compression; here you will learn about the different types of compression, the effect on bit rate and bandwidth, and how images are stored.

Module 3. The OSI Model
Here’s where we really begin to get into the nuts and bolts of transmission. You will gain a detailed understanding of the how OSI 7-level model came about and how it works, where the TCP, UDP and IP protocols fit in, together with an explanation of the various overheads and efficiencies which can be obtained.

Module 4. IP Addresses and Subnetting
In this module, you will be introduced to the IP version 4 addressing system, and cover the address classes, including the use of public and private addresses. The principles of subnetting are explained, starting from the question ‘why is subnetting necessary?’ The use of simple masks is explained, through to the complexities of Variable Length Subnet Masking, all with carefully worked examples to demonstrate the theory.

Module 5. IPv6
Module 5 deals with the exhaustion of IPv4 addresses, and the introduction of IPv6. You will understand from this module the principles of the classless address, globally routable addresses, and how one of the main benefits of IPv6 works – autoconfiguration. The module also deals with the issues of interconnecting IPv4 and IPv6 networks.

Module 6. Local Area Networks
The majority of CCTV systems run over a LAN of some sort. This module explains clearly the principles behind Ethernet, how the Network Card works, and the principles behind MAC addresses. You will also be introduced to some alternatives to Ethernet, and to the means of improving LAN performance, with concepts such as TCP offload engines and MTU Tweaking.

Module 7. Transmission Media
In this module we get to grips with the whole area of cabling – from coax through copper to optical fibre. You will understand the relationships between the various types of media and their bandwidth and range, important to know when selecting the right cable type for the job. We’ll cover coax cable, UTP, STP, FTP twisted pair copper, and single and multimode fibre, together with Coarse and Dense Wave Division Multiplexing, performance measurement and testing.

Module 8. Broadband
This module covers the whole area of broadband, frequently used to connect remote CCTV systems to a central point. Modulation schemes are explained, together with issues such as signal to noise ratios, and the international standards adopted for ADSL, SDSL and Rate Adaptive DSL

Module 9. Wi-Fi
In this module, you’ll be introduced to everything that goes on behind the scenes in wireless. From Wi-Fi to WIMAX, from link budgets to antenna types, all is revealed here. We cover the issues surrounding Quality of Service, an explanation of VLANs, together with tagging and trunking and much more relevant information for anyone designing a wireless CCTV system

Module 10. Routers and Routing
The ubiquitous router is the glue which holds networks together – but how do they really work? In this module you will learn how a routing protocol is chosen, how it ‘learns’, how it builds a routing table, how it advertises, and most importantly, how it chooses a route for an IP packet. We’ll explain RIP, OSPF, hop count, path costs, BGP4, how switched routers work and much more.

Module 11. Network Management
Understanding how a network operates and what can go wrong are the first steps to managing a system effectively, and this module explains clearly the principles behind Simple Network Management Protocol – SNMP. How remote devices signal their condition to a network management station is dealt with, and other useful tools and utilities, such as ping and tracert, are demonstrated.

Module 12. Security
The last module covers the whole area of network security. This is a vital topic to understand when designing a professional IP-based CCTV network. Here we cover firewalls, proxies, how IPSec works, and security in wireless systems. You’ll also have a clear understanding of when and where to use Network Address Translation, and how Port Forwarding works.
