Your CCTV cameras are only as reliable as the cables connecting them. While cameras and recorders get attention, cabling infrastructure determines image quality, system reliability, and future expandability. Poor cable choices lead to degraded video, frequent disconnections, and costly reinstallations. At IT Gallery Computers, we've learned that proper cabling makes the difference between systems that work flawlessly for years and ones causing constant headaches.

Understanding Your Cable Options

The cable type you need depends on your camera system. Analog and Turbo HD cameras use coaxial cables, IP cameras use Ethernet network cables, and large-scale installations may require fiber optic cables. Each has distinct advantages, limitations, and ideal applications. Choosing wrong cables can bottleneck your entire system, preventing cameras from reaching full potential.

Coaxial Cable: The Analog Standard

Coaxial cable remains the standard for analog and Turbo HD installations. These cables consist of copper core surrounded by insulation, braided shield, and outer jacket, providing good interference resistance and reliable signal transmission. RG59 is the standard choice for CCTV supporting runs up to 300 meters without signal loss, costing LKR 60-100 per meter, providing excellent quality for 1080p and 4K Turbo HD systems. RG6 offers thicker construction supporting 350 meters with superior interference resistance at LKR 80-120 per meter, ideal for challenging environments. For Sri Lankan installations, always choose pure copper core rather than copper-clad aluminum which degrades in tropical humidity. Look for 95% braided shielding minimum and UV-resistant outdoor-rated jackets essential for monsoon reliability. Remember coaxial carries only video, so separate power cables are required for each camera.

Ethernet Cable: The IP Camera Standard

Ethernet cables have become modern standard for IP installations, carrying both data and power through single cable using Power over Ethernet (PoE). This simplifies installation by eliminating separate power cables and enables advanced features like remote configuration. Cat5e supports up to 1 Gigabit speeds sufficient for cameras up to 5MP, with 100 meter maximum distance, costing LKR 40-70 per meter. Cat6 is recommended standard supporting 1 Gigabit reliably and handling 4K cameras easily with better interference resistance at LKR 60-100 per meter, providing excellent balance of performance and future capability. Cat6a supports 10 Gigabit speeds ideal for future-proof installations at LKR 100-150 per meter. For Sri Lankan conditions, outdoor-rated cables with UV-resistant jackets are essential. Choose solid copper conductors rather than aluminum for better longevity. Shielded cables provide better protection in electrically noisy environments though costing 20-30% more. Proper termination with quality RJ45 connectors is critical, as poor connections cause packet loss and camera disconnections.

Fiber Optic Cable: For Long Distance

Fiber optic cables use light signals enabling extreme distances and immunity to electromagnetic interference. While more expensive, fiber is essential for certain applications. It supports distances exceeding 10 kilometers without degradation, perfect for large campuses or remote monitoring. Fiber is completely immune to electrical interference and lightning, crucial near power substations. Single-mode fiber handles 2-100 kilometers for connecting buildings or remote sites at LKR 200-400 per meter. Multi-mode fiber suits distances up to 2 kilometers within large buildings at LKR 150-300 per meter. Installation requires specialized skills and equipment, with media converters needed costing LKR 15,000-50,000 per unit.

Cable Distance Limitations

Understanding maximum distances prevents failures. Coaxial supports 300 meters for RG59, 350 meters for RG6, requiring signal repeaters beyond. Ethernet supports 100 meters maximum when using PoE, extendable to 200 meters using PoE extenders at LKR 8,000-25,000. Fiber supports 2 kilometers for multi-mode and over 10 kilometers for single-mode. For exceeding limitations, use network switches every 100 meters for Ethernet, signal amplifiers every 200-300 meters for coaxial, or fiber converters for extreme distances.

Installation Best Practices

Plan cable routes avoiding electrical interference by keeping 30 centimeters from power lines, away from motors and transformers. Use conduits for outdoor runs protecting from weather and UV at LKR 200-500 per meter installed. Leave service loops at both ends allowing adjustments without replacement. Label all cables clearly for easy troubleshooting. Test every run before connecting equipment using cable testers costing LKR 5,000-30,000. Secure cables with mounting clips every 30-50 centimeters preventing sagging.

Common Mistakes to Avoid

Using cheap copper-clad aluminum saves money initially but degrades rapidly in Sri Lankan humidity, failing within 1-2 years. Exceeding maximum distances results in poor image quality and dropped connections. Running cables alongside power lines causes visible interference. Inadequate weatherproofing allows moisture ingress leading to failures during monsoons. Poor termination creates intermittent connections. Not planning for expansion requires costly reinstallation when adding cameras.
