Detailed Module Breakdown

Module 1: Foundations (4 Lessons)

Every reliable CCTV system starts with solid planning, and this opening module gives you the tools to plan like a professional. You will learn the DORI framework—a standardised method for defining exactly what a camera needs to achieve at a given distance, measured in pixels per metre (PPM). We then move into threat assessment methodology, teaching you how to evaluate a site, identify risks and prioritise camera positions. You will discover the four-layer camera placement strategy used by professional security consultants, and finish with a clear picture of end-to-end system architecture across analogue, HD and IP technologies. This module ensures you never place a camera without a reason.

Module 2: How Cameras Work (4 Lessons)

Before you can choose the right camera, you need to understand what is happening inside it. This module opens up the technology behind modern surveillance cameras. You will compare CCD and CMOS sensors, learn how sensor size affects image quality and light sensitivity, and see how the Bayer filter creates colour from a monochrome sensor. We cover lens types—fixed, varifocal and motorised—so you understand focal length, field of view and depth of field. The module concludes with the image processing pipeline, video compression standards (H.264, H.265, MJPEG), white balance and exposure control. After these four lessons, camera spec sheets will make complete sense.

Module 3: Resolution & Image Quality (3 Lessons)

Megapixels sell cameras, but pixels per metre determines whether your footage is actually useful. This module traces the resolution progression from CIF through to 4K, explains what megapixel ratings really mean, and then shows you why PPM is the only metric that matters for identification and evidence. You will learn how to calculate PPM for any camera and lens combination, and how to select the right frame rate—from 1 fps for a quiet car park to 25–30 fps for a busy entrance. This is the module that separates installers who guess from installers who know.

Module 4: Challenging Conditions (3 Lessons)

Real-world surveillance rarely happens in perfect lighting. This module prepares you for the conditions that catch beginners off guard. You will learn how active infrared LEDs and laser illuminators extend night vision, how thermal imaging detects intruders in complete darkness, and how starlight sensors capture usable colour images in near-zero light. We cover wide dynamic range (WDR) for scenes with extreme contrast—think a camera pointed at a glass entrance on a sunny day—and finish with environmental challenges: rain, fog, dust, vibration and temperature extremes, along with the protective housing solutions that keep your cameras running.

Module 5: Camera Types & Form Factors (5 Lessons)

With five lessons, this is one of the largest modules, and for good reason: choosing the wrong camera type is one of the most common mistakes in CCTV installation. You will learn the strengths and weaknesses of dome, bullet, turret and box cameras, and when each is the right choice. We dedicate a full lesson to PTZ cameras—presets, tours, speed domes and their role in active monitoring. Fisheye and multi-sensor cameras get their own lesson covering dewarping, virtual PTZ and panoramic coverage. You will also explore thermal cameras including radiometric models that measure temperature, and audio surveillance with two-way communication. By the end, you will select camera types with confidence for any scenario.

Module 6: Analogue, HD & IP (4 Lessons)

The CCTV industry spans three generations of technology, and as an installer you will encounter all of them. This module starts with traditional analogue—coaxial cable, BNC connectors, DVRs and the PAL/NTSC standards—because millions of these systems are still in service. We then cover HD-over-coax technologies (TVI, CVI, AHD, HD-SDI), which deliver high-definition video over existing coax infrastructure. The IP camera lessons explain network-based surveillance, streaming protocols, Power over Ethernet and cloud connectivity. The final lesson provides a clear technology comparison and upgrade path, so you can advise clients on the most practical route forward for their existing infrastructure.

Module 7: Powering Cameras (3 Lessons)

A camera without reliable power is just a decorative housing. This module covers the three main approaches: Power over Ethernet (PoE) using IEEE 802.3af (15W), 802.3at (30W) and 802.3bt (60–90W) standards; 12V DC and 24V AC local power supplies; and how to choose between them. You will learn power budget planning—adding up every device on every switch and ensuring your supply has headroom—and UPS sizing to keep your system running during mains failures. These are the calculations that prevent the single most frustrating fault in CCTV: unexplained camera dropouts.

Module 8: Cabling & Transmission (5 Lessons)

This five-lesson module is your complete guide to getting signals from camera to recorder. We cover structured copper cabling—Cat5e, Cat6 and Cat6A—with distance limits and performance characteristics. Coaxial cable for analogue and HD-over-coax systems gets its own lesson. You will learn when and how to use fibre optics (single-mode and multimode) for long runs and electrically noisy environments, and explore wireless transmission options including WiFi, point-to-point links and 4G/5G cellular. The module finishes with cable installation best practices and hands-on guidance for BNC and RJ45 termination. If the cable is wrong, nothing else matters—this module makes sure you get it right.

Module 9: Video Compression & Bandwidth (3 Lessons)

High-resolution cameras are useless if your network cannot carry the data. This module explains H.264 (10–20x compression), H.265 (roughly twice as efficient as H.264), and MJPEG for specialist applications. You will understand the difference between variable bitrate (VBR) and constant bitrate (CBR), learn how I-frame intervals affect both quality and bandwidth, and see how adaptive bitrate helps balance quality against available bandwidth. These three lessons give you the knowledge to configure cameras that deliver clear images without overwhelming your network.

Module 10: Recording & Storage (7 Lessons)

With seven lessons, this is the largest module in the course, reflecting the importance of getting recording right. You will compare HDD and SSD storage, learn why surveillance-grade drives exist and when to use them, and understand RAID configurations for redundancy and performance. We then provide complete DVR and NVR setup walkthroughs—step by step, screen by screen. The final lessons cover Video Management Software (VMS) platforms at the enterprise level, including federation, API integration, user roles and permissions, and interactive map views. Whether you are setting up a four-camera shop or a 500-camera campus, this module has you covered.

Module 11: Networking for CCTV (6 Lessons)

Modern CCTV runs on IP networks, and this module ensures you can design and manage them properly. Starting with IP addressing, subnets and DHCP, we build up through managed vs unmanaged switches, VLANs for traffic segregation and Quality of Service (QoS) to prioritise video. You will learn the ONVIF profiles that enable interoperability between manufacturers. The final two lessons focus on cybersecurity—first the fundamentals (passwords, firmware, disabling unused services), then a deep dive into zero-trust architecture for surveillance networks. This module is also where the bundled Network Fundamentals for Security Engineers course proves invaluable, giving you 92 additional lessons of dedicated networking knowledge.

Module 12: Storage Calculation & Recording Modes (4 Lessons)

How much storage do you actually need? This module gives you the formulae and methodology to calculate it accurately for any project. You will compare recording modes—continuous, scheduled, motion-triggered, event-driven and dual-stream—and understand how each affects storage consumption. We cover retention periods and how regulations like GDPR influence how long you can keep footage. The module concludes with disaster recovery planning and RAID failover strategies, so you can design systems that survive hardware failures without losing critical evidence.

Module 13: Viewing, Export & Evidence (5 Lessons)

Recording footage is only half the job—you also need to find, review and export it. This module covers live viewing and latency management, smart search and playback tools that save hours of manual review, and the critically important topic of evidence export. You will learn how to export footage with watermarking and chain of custody documentation that holds up in court. We cover remote access (VPN vs port forwarding, and why the latter is almost always the wrong choice), and finish with multi-site federated monitoring for organisations managing cameras across many locations.

Module 14: Installation Practices (4 Lessons)

This module bridges the gap between theory and the real world. You will learn how to conduct a proper site survey, applying the DORI principles from Module 1 to determine exact camera positions and mounting heights. We cover mounting techniques and weatherproofing—IP ratings, cable glands, drip loops and conduit runs. The commissioning and handover lesson teaches you to test, document and formally hand a system over to the client. The final lesson walks through three real-world job scenarios—residential, commercial and enterprise—showing how the scale and complexity of the installation process changes at each level. This is your CCTV installation training in practice.

Module 15: Integration & Analytics (4 Lessons)

Standalone CCTV is increasingly rare. This module shows you how surveillance systems integrate with the wider security ecosystem. You will learn how to connect cameras with intruder alarm and access control systems for event-triggered recording and automated responses. We cover video analytics—motion detection, line crossing, people counting and loitering alerts—and explore where AI and cloud technologies are taking the industry. The final lesson focuses on ANPR (Automatic Number Plate Recognition), covering how it works, where it is deployed and what the accuracy expectations are in practice.

Module 16: Troubleshooting & Maintenance (3 Lessons)

When a system goes wrong, the client calls you. This module prepares you for that call. You will work through systematic diagnosis of the most common faults: no video, intermittent connections, low frame rates and recording gaps. A dedicated lesson covers image quality problems—blurring, IR reflection, colour shift and compression artefacts—with practical fixes for each. The final lesson helps you build a preventive maintenance schedule that catches problems before the client notices them, protecting both the system and your reputation.

Module 17: Privacy & Compliance (3 Regional Variants)

Privacy law is not optional, and getting it wrong carries serious penalties. Rather than delivering a generic overview, this course provides three dedicated regional compliance modules—and you see only the one that applies to you:

• EU/UK variant: GDPR, the Data Protection Act 2018, ICO guidance, lawful basis for processing, data subject access requests, Data Protection Impact Assessments (DPIA) and retention rules
• USA variant: CCPA, BIPA, state-by-state variability, two-party consent laws and workplace monitoring rules
• International variant: Universal privacy principles, regional standards and industry-specific regulations including HIPAA, PCI-DSS and FERPA

This approach means you spend your study time on the laws that actually affect your work, not wading through regulations from jurisdictions you will never operate in. It is a feature we believe makes this one of the most practical CCTV courses online available anywhere.
