Fast access to CCTV leads and installation-ready cabling
If you need CCTV leads in stock today, Communica offers a practical, locally focused range of coax, Siamese power/video leads, BNC crimp connectors, DC power leads and pre-assembled extension cables from brands engineers trust. We prioritise availability so technicians, installers and procurement teams in South Africa can finish jobs on time - with VAT invoices, branch collection and account quoting to simplify procurement.
What’s in stock and why it matters
Stocked items are chosen for real-world CCTV installation use: low-loss RG59/RG6 coax for longer runs, Siamese cable for combined video and power, pre-terminated leads for quick camera swaps, and assorted BNC/terminal adaptors for on-site compatibility. That practical selection reduces troubleshooting time and avoids repeat site visits.

Quick specification table - choose the right lead
This comparison helps pick the correct cable for a typical CCTV run.
| Type | Best for | Max recommended run | Notes |
|---|---|---|---|
| RG59 Coax | Standard analog CCTV | up to 100 m | Low cost, common stock |
| RG6 Coax | HD video over coax (longer runs) | up to 200 m | Lower attenuation than RG59 |
| Siamese (Coax + 2 power conductors) | Single-cable video + power | depends on power draw | Reduces conduit runs |
| Pre-terminated leads | Rapid replacement | as required | Saved labour time on-site |

When runs exceed recommended lengths, use higher grade coax or add a local power supply at the camera. Need to verify exact part numbers and lead lengths? order-cctv-leads-online to filter by cable type and termination.
Accessories and compatibility tips
- Bring a camera sample or model number when buying connectors to ensure mating fit.
- Stock common BNC variants (crimp, compression, push-on) for field flexibility.
- Keep spare DC barrels and pigtails - they’re low cost and save repeat trips.
