Belden 649948 877 is a plenum-rated PTZ (CCTV + Power/Audio) composite cable built in a Siamese construction for surveillance and CCTV camera installations, including PTZ (Pan-Tilt-Zoom) systems. It combines 1-RG59 coax with a 20 AWG solid bare copper conductor and a 95% bare copper braid to support 75 Ohm video performance. An attached 1-18 AWG stranded bare copper pair (7x26) supports power/audio needs. The cable uses Flamarrest® insulation and a Flamarrest® jacket with NFPA 262 compliance and a 300 V RMS UL voltage rating for indoor plenum spaces.
