9 Video and Control Cables (AUTODOME VG5-600
Camera Models ONLY)
This chapter applies only to AUTODOME cameras.
9.1 Using Coaxial Cable to Transmit Video and Control
!
Caution!
^
600 Series AUTODOME : If you are using coaxial cable to transmit video and data between the
camera and the head-end, you must use the coax cable with ferrite included in the camera
packaging. You must connect the incoming coax cable (from the head-end) to the jack (female
end) on the ferrite cable and connect the plug end (male connector) of the ferrite cable to
the camera’s coax connector.
Coaxial cable terminated with BNC connectors is the most common method for transmitting
composite video. Bilinx control data can also be sent over the same cable.
Bilinx is a Bosch 2-way communication protocol that allows remote control, configuration, and
updates over a video coax cable. Bilinx is available on all VG5 100 and 600 Series cameras.
AUTODOME VG5 Series cameras feature cable compensation or “Pre-Comp,” which extends
the range of video from the head end.

Warning!
Cable compensation (Pre-Comp) does not extend the range of Bilinx control. Pre-Comp is not
available with VG5 700 Series cameras.
9.2 Using UTP to Transmit Video and Control
Unshielded twisted pair (UTP) cable terminated with RJ45 male connectors are used to
transmit composite video using pins 1(+) and 2(-). Typically, a Coax to UTP cable converter is
required at the head-end of the system.
Bilinx control data can also be sent over the same two video wires (1 & 2). Bilinx is a Bosch 2-
way communication protocol that allows remote control, configuration and updates over a
passive UTP cable.
