Installation
Star-Connection-
The star-form connection is most commonly used. It enables the connection of different dome
cameras with longer cable runs. It is recommended to use an RS485 distributor to ensure the
telemetric data transmission.
The advantage of the star-connection is that every channel can work independently and can
take a cable length up to 3,280 feet (1000 meters) (depending on cable quality). In cases where
more dome cameras are installed, the star-connection can be extended with additional RS485
distributors.
Video Cable-
Coaxial cable with 75Ω impedance with copper conductor at center conductor, and shielded
with 95% copper. The following table shows different cable type and its maximum length:
If the cable length is more than 1,312ft (400m), it is recommended to use optional accessories,
such as a video amplifier or twisted-pair video converter, for boosting the video signal.
