  • Overall length250 ft (76.2 m)

Cable Length 250 Feet

  • Transmits 1080P60 video up to 100 metres
  • 75-ohm shielded coax rejects electromagnetic interference

  • 3 GHz sweep tested for verified signal quality
  • Single 250 ft run replaces separate video and power cables

250 ft SDI Siamese Cable

This 250 ft BZBGEAR BG-CAB-SDIS250 cable combines a 75-ohm shielded coaxial run with an 18-gauge stranded copper pair. It carries 3G-SDI video and DC power or RS232/485 control on a single pull. BNC connectors terminate both ends for professional broadcast and security gear.

Installers needing combined video and power

The siamese construction suits fixed or temporary runs where a camera requires both signal and low-voltage supply over distance. It supports 1080P60 at up to 100 m and is sweep tested to 3 GHz for artifact-free transmission. Systems demanding 4K resolution, fibre linkage or connector types other than BNC fall outside this cable’s design.

75-ohm shielded coaxial with 18-gauge power pair

The defining specification is the integrated 2-conductor copper wire alongside the SDI conductor. This single-cable topology reduces installation labour and conduit fill for compatible 3G-SDI devices. Verify that the connected equipment uses BNC interfaces and operates within the 1080P60 envelope before specifying this part.

Questions about this item

How far can the BG-CAB-SDIS250 carry a 1080P60 signal before it degrades?

The cable is rated to transmit 1080P60 video up to 100 m, which matches its 250 ft length.

Does the BG-CAB-SDIS250 get hot or draw extra power when run continuously?

The coaxial line is passive and generates no heat; only the 18-gauge copper pair carries DC or serial current.

What connectors or devices must I already have to use the BG-CAB-SDIS250?

You need equipment with BNC ports for the SDI signal and a two-wire terminal for the 18-gauge power or RS-232/485 pair.
