Why order CCTV leads from a local distributor
- Reduced lead times - common cable types and connectors held in regional branches to keep installations moving.
- Practical compatibility guidance for analogue and IP CCTV systems so you select the right cable for distance and bitrate.
- Documentation and VAT invoicing that supports tendering, education projects and company procurement.
Quick spec comparison
| Cable type | Best for | Typical max run |
|---|---|---|
| RG59 coax | Analogue CCTV, short runs | Up to 100 m |
| RG6 coax | Longer runs, better shielding | 100-200 m |
| Siamese (Coax + Power) | Analogue with single-cable power | Depends on power drop; typically 50-100 m for 12 V |
| Cat5e/Cat6 (HD over UTP) | HD-TVI/AHD over baluns, PoE for IP cameras | 100 m standard (PoE) |
Key selection guidance (distance, signal, and power)
Match cable type to camera technology and run length. For IP cameras using PoE, Cat5e is the baseline; choose Cat6 for runs near 100 m or where higher thermal derating is a concern. For analogue HD formats, select RG6 for longer runs to reduce attenuation. When power is run alongside video, check voltage drop and use the wiring table below to estimate conductor size.
| Voltage | Conductor | Typical safe run |
|---|---|---|
| 12 V | 2.5 mm² | up to 40-60 m depending on camera current |
| 12 V | 1.5 mm² | up to 20-40 m |
| 24 V | 1.5 mm² | longer runs possible with lower drop |
Simple power drop formula to estimate voltage at the far end: V_drop = I × R_run where R_run = (resistance per metre × total length both conductors). For quick checks use conductor resistance charts on product pages and ask our tech team for confirmation when in doubt.
Accessories and bundles to speed installation
- Pre-crimped BNC leads and bulk coax reels for fast deployment.
- Siamese cables paired with 12 V power supplies sized for multiple cameras.
- Balun kits, PoE injectors, and shielded patch leads for mixed analogue/IP sites.
