Does my camera need Siamese RG59 or RG6 with a power pair?
Siamese camera cable combines a coaxial path and a separate power pair in one bonded assembly. Confirm that your camera and recorder use that arrangement. A camera with an Ethernet/PoE interface calls for a different type of link.
Which half of the description am I reading?
RG59 and RG6 identify the coax family. A designation such as 18/2 describes the separate two-conductor power pair. Compare both sections to the approved camera specification, including the installer’s allowable distance and power requirements. A compatible video path does not establish the power design.
What comes terminated?
A spool supplies bulk cable. A DC plug-to-terminal adapter is an accessory, and many installations also require compatible coax ends. Have the installer identify the exact connector dimensions and list the quantity needed for each camera location.
How do I compare existing runs and new camera locations?
Make a row for each camera showing run length, recorder interface and approved local or remote power arrangement. A new location may look identical from the recorder rack while its power source is differently arranged. Review those rows with the installer before combining several camera runs into one reel estimate.
Identify both halves of a camera home run
A legacy analog camera run may have a coax section for the picture and a bonded pair for power. The 10X3-18291TF lists RG59 video coax with 18/2 stranded copper power conductors. Note both constructions and the system design when comparing replacements. An accessory such as a DC plug adapter may appear in the same category without supplying any cable footage. Ask the installer for the longest route and the equipment’s power and video requirements before choosing reel size. Label the destination at the recorder cabinet so the bonded run remains traceable during a camera replacement.
RG59 Siamese and RG6 Siamese are not identical camera runs
Two bonded camera cables may both describe an 18/2 power pair and still use different coaxial constructions. The 10X3-18291NH lists RG59 with a solid copper coax center. The 10X4-18912NH lists RG6 with a copper-clad steel coax center. Start with the camera and recorder design, the planned route and the length of each run. Ask the installer to confirm the video specification, power requirements, jacket classification and connectors that fit the chosen construction. For an outdoor transition or return-air space, have the approved location requirements identified before buying a reel. When comparing quotes, specify each half of the assembly and the length per reel. That keeps a superficially similar bonded cable from being approved solely because the power conductor count and the box color happen to match.
