Video Cable
coaxial cable with 75
impedance with copper conductor at center conductor, and
shielded with 95% copper. The following table shows different cable type and its
maximum length:

The values are for reference only.
Depends on the cable quality and
environmental condition, the
transmission distance might be less.

If the cable length is more than 400 m, it is recommended to use optional
accessories, such as video amlifier(e.g AU-VD-1001) or twisted-pair video
converter (e.g. AU-TP02 or AU-TP08), for boost the video signal.

G65 and G70 series domes provide integrated termination switch. It should be
turned on when the dome is installed as the last device. If the controller keyboard
is used such as AU-KB3A, you need also to turn on the termination on it. please
refer to the keyboard’s manual for details.
RS-485Termination
Devices using Rs485 control are usually connected in daisy-chain. which reqiuers
termination with 120
resistor on both ends. Following picture illustrates the
connection methods. please note that a daisy-chain connection type shall not
exceed 7 meters.

How to turn on termination on G65 and G70
The termination switch is located on the rear side of the connection board. For
switching on, you need to open the
Star-Connection
The star-form connection is mostly used. it enables the connection of different dome
cameras in longer distance. It is recommended to use RS-485 distributor (e.g AU-VC-
MC2088) to ensure the telemetric data transmission:
The advantage of star-connection is
that every channel can work
independently and take a cable
length up to 1000 meters( depends
on cable quality). In case more
dome camera are installed, the star-
connection can be extended with
additional RS-485 distributors.
