Network Fundamentals Training Course for Security Engineers
The Complete IP Networking Course for CCTV, Access Control & Security System Professionals — From Absolute Zero to Enterprise-Scale Design
The BH Courses Network Fundamentals Training Course is the most comprehensive IP networking course available specifically for the security industry. Designed for CCTV installers, access control engineers, intruder alarm technicians, intercom engineers, electricians, and complete beginners, this course assumes absolutely zero prior networking knowledge and builds your confidence to design, configure, and troubleshoot IP-based security networks from small residential systems to large enterprise installations.
If you work with — or plan to work with — IP cameras, network video recorders, IP access control panels, IP intercoms, or any IP-enabled security device, you need to understand networking. This is not optional. Every modern security system runs on a network, and technicians who lack networking skills are increasingly unable to install, configure, or troubleshoot the systems they are responsible for.
With 92 lessons across 20 modules and approximately 8 hours of structured training, this is not a quick overview bolted onto a CCTV course. This is a complete, standalone networking programme built from the ground up for security industry professionals. It uses physical-world analogies throughout — postal systems, roads, buildings — to make every concept accessible, regardless of your technical background. Course also available on our UK website: Network Fundamentals Training
Why This IP Networking Course Is Different
- Built specifically for security engineers, not IT professionals: Unlike generic CompTIA or Cisco networking courses, every concept is taught through the lens of CCTV, access control, intruder alarms, and intercoms. You learn networking the way you will actually use it in the field — configuring IP cameras, setting up PoE switches, designing VLAN-separated security networks, and troubleshooting real installation problems.
- Starts from absolute zero: You do not need any prior networking knowledge. The course begins with what a network is and builds systematically through IP addressing, switches, PoE, routers, VLANs, wireless, bandwidth, cybersecurity, and full system design. If you can use a web browser, you can take this course.
- 92 lessons across 20 structured modules: This is the most detailed networking course available for the security industry. Most CCTV courses include a few networking videos as an afterthought — this course is dedicated entirely to giving you a thorough, practical understanding of IP networking.
- Physical-world analogies throughout: Every concept is explained using real-world comparisons — postal systems for TCP/IP, roads for bandwidth, house addresses for IP addressing, buildings for VLANs. You do not need a computer science background to understand this material.
- Covers the full range of security systems: Not just CCTV. The course includes examples and scenarios for IP cameras, NVRs, VMS platforms, access control panels, intruder alarm communicators, IP intercoms, and other IP-enabled security devices.
- Includes hands-on practical skills: Guided lessons on changing IP addresses, device discovery, camera configuration, PoE switch setup, cable testing, and secure remote access — the exact tasks you will perform on every installation.
- Cybersecurity included: Security systems are a common target for hackers. The course covers password management, firmware discipline, network segmentation, encryption, and how to protect the systems you install from cyber attack.
- Complete real-world installation scenarios: Design and configure networks for four progressively complex installations — from a 4-camera residential system through to a 200+ camera enterprise campus with fibre backbone and VLANs.
- Designed for Irish & International learners: Widely used by Irish security companies, electricians, and technicians. All content is universal and not tied to any single manufacturer or country's regulations.
- 7 days of unlimited online access: Complete the course at your own pace, on your own schedule, without disrupting operations.

What You Will Learn (92 Lessons, ~8 Hours)
The course progresses logically from foundational concepts through to complete real-world installation design. Every module builds on the one before it, and by the end you will have the knowledge and confidence to design, configure, and troubleshoot IP networks for any security installation.
Starting From Zero — What Networks Are and How They Work
Understand why networking now matters for every security engineer — the entire industry has shifted to IP. Learn what a network actually is using a roads and addresses analogy, the difference between LAN and WAN, what the internet is (and is not), and an overview of all major network device types. Understand what a protocol is, how TCP/IP works as the universal network language using a postal system analogy, how data packets are structured and reassembled, the difference between MAC addresses (permanent device identifiers) and IP addresses (changeable network addresses), and follow a real-world walkthrough of how a video stream travels from an IP camera to an NVR through switches and network devices.
IP Addressing — The Foundation of Every Security Network
Master IP addresses from scratch: reading and writing the four octets (0–255), understanding the network part vs device part using a streets and house numbers analogy, subnet masks (primarily 255.255.255.0) with CIDR notation, and the default gateway as the only route off your local network. Learn static IP assignment and why every security device should use it, DHCP automatic assignment with reservations, how to diagnose and prevent IP address conflicts, and the difference between private IP addresses (192.168.x.x, 10.x.x.x) and public IP addresses with NAT translation.
Ports, DNS & Time Synchronisation
Understand what ports are — 65,535 doors inside every device — and learn the specific ports used by security systems: port 80 (HTTP), 443 (HTTPS), 554 (RTSP video streaming), 8000/8080 (Hikvision/Dahua proprietary), 37777/37778 (Dahua), 5060 (SIP for intercoms), 123 (NTP time sync), and 3702 (ONVIF device discovery). Grasp the difference between TCP (guaranteed delivery) and UDP (fast delivery) and when each is used in video streaming. Learn port forwarding risks and safer alternatives for remote access. Cover DNS as the phone book of the internet, DDNS for when your public IP keeps changing (essential for remote CCTV and access control), and NTP time synchronisation — critical for forensic evidence that requires accurate, synchronised timestamps across all cameras and recording devices.
Cabling — The Physical Layer of Every Installation
Learn what Ethernet is, cable categories and their real-world performance (Cat5e for 100 Mbps, Cat6 for 1 Gbps, Cat6A for 10 Gbps), what is inside the cable and why the wires are twisted. Follow a practical, step-by-step RJ45 crimping lesson. Understand the 100-metre maximum distance rule and the solutions for longer cable runs. Cover fibre optic basics — single-mode vs multimode, when to use each, and how media converters bridge fibre and copper networks.
Switches & Power over Ethernet (PoE) Training
Understand what a network switch does and how switches learn MAC addresses to forward data intelligently. Learn the difference between unmanaged switches (plug and play) and managed switches (VLANs, QoS, monitoring, port control). Cover Power over Ethernet in depth — the technology that delivers both data and power to IP cameras, access control readers, and IP intercoms over a single Ethernet cable. Learn PoE standards: 802.3af (15.4W, sufficient for most fixed cameras), 802.3at (30W, for PTZ cameras and high-power devices), and 802.3bt (60–100W, for PTZ speed domes and heated housings). Understand the power budget trap — why switches run out of power before they run out of ports — with capacity planning techniques. Learn about PoE injectors and extenders for adding power where switches cannot reach, and how to systematically troubleshoot PoE when devices will not power up.
Routers, VLANs & Wireless Networking
Understand what a router does as the gateway between your security network and the outside world. Learn how NAT allows an entire building to share one public IP address, how firewalls work with default-deny rules, and why VPN is the secure alternative to exposed port forwarding for remote access. Understand why security devices should never share a network with office computers, what VLANs are (invisible walls inside your switch that separate traffic), how to design VLAN layouts that isolate CCTV, access control, and intercom traffic from corporate networks, and practical VLAN setup with tagged, untagged, and trunk ports. Cover WiFi and why it is generally unsuitable for professional security installations, wireless bridges for connecting buildings without cable using point-to-point directional antennas, and cellular connections (4G/5G) for remote sites.
Bandwidth, Video Compression & Storage
Master the bandwidth concept using a motorway analogy — how much data your network can carry and how to ensure it is enough. Calculate exactly how much bandwidth each IP camera uses based on resolution, codec (H.264 vs H.265), and frame rate. Assess available network capacity on Gigabit switches and WAN connections. Determine whether your network infrastructure will cope before you install a single camera. Cover raw video size and why compression is essential, the practical differences between H.264 and H.265, and bitrate encoding (VBR vs CBR) with quality implications. Learn hard drive types, surveillance-rated drives, RAID levels (0, 1, 5, 6) with practical differences, NAS storage, and how to calculate storage requirements for any security installation.
Servers, Software & Remote Access
Understand server and client architecture, security-specific servers (NVR, VMS, access control servers), web interfaces for device management, and how to set up mobile apps for remote viewing.
Practical Hands-On Skills
Apply everything you have learned in guided, practical lessons: changing IP addresses on security devices, device discovery using ping, ARP, and network scanning tools, logging into an IP camera for the first time, PoE switch setup and configuration, cable testing and verification, and setting up secure remote access using VPN.
Cybersecurity for Security Systems
Security systems are increasingly targeted by hackers — and poorly secured cameras, NVRs, and access control panels are common entry points into corporate networks. Learn hacker motivation and the most common attack vectors targeting security installations, password strength and management best practices, firmware update discipline, network segmentation as a primary defence strategy, and encryption for protecting video streams and device communications.
Network Troubleshooting
Master systematic troubleshooting methodology that saves hours on site. Learn to diagnose no-connection problems, slow video and buffering issues, remote access failures, and build your essential network troubleshooting toolkit — the commands, tools, and techniques every security engineer should have at their fingertips.
Complete Real-World Installation Scenarios
Bring everything together with four progressively complex system design scenarios that mirror real jobs: a small residential system (4 IP cameras with a single PoE switch), a medium commercial system (32 cameras with managed switches and VLANs), a large campus system (200+ cameras with fibre backbone, multiple switches, and enterprise VMS), and detailed guidance on how to coordinate effectively with IT departments — a skill that separates professional security engineers from basic installers.

Why IP Networking Skills Are Essential for Security Engineers
The security industry has fundamentally shifted from analogue to IP. Every major system category — CCTV, access control, intruder alarms, intercoms, fire detection — now uses IP-based technology. Technicians who do not understand networking are increasingly unable to install, configure, troubleshoot, or maintain the systems they work with every day.
This is not just about CCTV. Access control panels communicate over IP. Intruder alarm systems use IP communicators. Intercoms run on SIP over IP networks. Fire panels connect via Ethernet. If you install or maintain any of these systems, networking knowledge is no longer optional — it is a core professional skill.
This course gives you that skill, from absolute zero to professional competence, in a format designed specifically for how security engineers learn and work.
