VideoSecu CBS500B 500 ft Siamese Cable

This 500-foot RG59 18/2 Siamese cable combines a 20AWG bare copper coaxial conductor with 95% copper braid and two 18AWG stranded power wires in a single black sunlight-resistant PVC jacket. The reel-in-box design allows easy, tangle-free pulling during installation. It carries both video and power for CCTV cameras in one cable run. The construction suits analog security systems and basic residential antenna feeds.

Ideal for single-cable CCTV installs.

Installers wiring analog cameras over long distances benefit from the combined video and power conductors and the sunlight-resistant jacket for outdoor runs. The package includes only the bulk cable on a reel, so connectors and power pigtails must be sourced separately. Projects requiring network-grade twisted pair or fibre connectivity should select a different cable type. Builders needing pre-terminated lengths will not find them here.

500-foot RG59 18/2 length with 95% copper braid

The 500-foot reel provides a continuous 20AWG RG59 coaxial core with 95% copper braid shielding alongside two 18AWG stranded power conductors. This specific combination determines the maximum video run distance and the current available for camera power. Verify that the run length and camera power draw match these conductors before purchasing.

Questions about this item

Will the 20AWG RG59 coax with 95% copper braid work with my existing analog CCTV cameras?

Yes, the RG59 video cable accepts standard RG59 coax connectors such as twist-on BNC, so it connects directly to analog cameras that use that interface.

How can I verify the cable is carrying both video and power correctly after installation?

Check for a clear picture on the monitor and confirm the camera LEDs are lit; the two 18AWG stranded conductors deliver power while the 20AWG coax carries the video signal.

Does the 500-foot reel-in-box include any connectors or do I need to buy BNC and power pigtails separately?

The box contains only the 500-foot siamese cable; BNC connectors and power pigtails are sold separately.
