RG59 Siamese Cable for AHD TVI CVI HD-SDI Camera Systems - 4-Pack 100

Our review of this RG59 Siamese cable finds it best for installers and DIYers who need reliable, long runs for analog and HD surveillance cameras. The single biggest reason to buy is straightforward: it combines an RG59 video conductor and an 18-2 power pair in one plug-and-play assembly, so setting up BNC-equipped AHD, TVI, CVI or HD-SDI cameras is faster and neater than running separate cables. The included BNC video and 2.1mm power connectors reduce connector work, and the 4-pack of 100 ft lengths suits multi-camera installs without frequent joins.

Key Features

• Siamese construction: video and power in one jacket minimizes cable clutter and speeds installation for multi-camera systems.
• RG59 video conductor: designed to minimize interference and support long distance signal transmission for analog and HD-over-coax formats.
• 18-2 power pair: supplies camera power alongside the video line so you avoid running separate power runs and extra connectors.
• BNC and 2.1mm connectors: plug-and-play ready with common BNC video and 2.1mm power plugs for quick connections at camera and DVR ends.
• Compatibility: works with TVI, CVI, AHD and HD-SDI camera systems and can adapt to RCA where needed.
• Pack size: four 100 ft cables provide enough length for small to medium residential or commercial installations.

Who It's For

This cable set is aimed at homeowners, small business owners and installers who need reliable coax with integrated power for CCTV runs of up to 100 ft per cable. The 4-pack format makes it convenient for completing a 3- or 4-camera layout without buying singles and offers consistent cable quality across runs.

It is not targeted at projects requiring networked IP cameras, PoE, or custom gauge power solutions; those users should choose Cat5e/Cat6 or specialized power distribution systems instead. If you need extremely long runs beyond 100 ft without a booster, consider higher-spec transmission solutions.

Pros & Cons

Pros

• Good cable quality and durable jacket for standard CCTV installations.
• Combines video and power to reduce installation time and material cost.
• Works with multiple HD-over-coax standards (TVI, CVI, AHD, HD-SDI) and BNC/RCA options.

Cons

• Limited to analog and HD-over-coax camera systems, not suitable for PoE IP cameras.
• 100 ft length may require amplifiers or thicker conductors for very long-distance power delivery.

Specifications

Our Verdict

For anyone wiring multiple analog or HD-over-coax cameras, this RG59 siamese 4-pack is a practical, cost-effective choice that simplifies runs and connector work. The integrated BNC and 2.1mm power plugs and consistent cable quality make it good value for typical residential and small commercial surveillance installs, while users needing IP or long-distance PoE should look to other cabling solutions.

Frequently Asked Questions

Can this cable power cameras directly?
Yes; the 18-2 power pair with 2.1mm power jack can deliver camera power, but check voltage drop over long runs and camera power requirements.

Will it work with my DVR?
It supports BNC video inputs common on DVRs for TVI, CVI, AHD and HD-SDI systems and can adapt to RCA where required.

Are these cables ready to use out of the box?
Yes; the cables come with BNC video and 2.1mm power connectors for plug-and-play connections.
