Ideally being used in indoor installation circumstances, a Connector Box provides easy wiring and well organized
connection between alarms, cameras and other devices, for easy installation.
To connect the connector box with other devices:
Use a RS-485 cable (CAT 5 is recommended) to complete RS-485 communication wiring with control devices •
such as DVRs and Control Keyboards.
Use a 22-pin cable to connect the connector box to the dome.

For more detailed information, please refer to the connector box user’s manual. A system wired with a connector box
is illustrated in the following diagram.

CONNECTING WITH CONNECTOR BOX
To integrate other surveillance devices with the Speed Dome Cameras, we provide three kinds of converter/repeater
to transform the communication formats between devices. If a converter/repeater is used, the total network distance
of the surveillance system can be extended, and the connected devices will also be protected. Up to 10 devices are
allowed to connect to each repeater. For more detailed information, please refer to the converter/repeater user’s
manual.

The RS-485 Signal Distribution Unit (SDU) is designed to relay control codes to Speed Dome Cameras. It is capable
of communicating with cameras up to 1.0 kilometers away. Additionally, the SDU can be installed in either “star” or
“daisy chain” configuration with up to 160 cameras (see the diagrams below). Its versatile installation configuration
makes an easy integration into expanding surveillance systems. For more information, please refer to the SDU
user’s manual.
