Connecting Multiple PTZ Systems
Connecting multiple PTZ systems to the included controller is a convenient way to
be able to access and control a complex, multi-camera system from one central
location. This is, however, and advanced feature of PTZ systems, and should
only be attempted by those experienced with security system and/or networking
technologies. In a nutshell: multiple systems can be connected to the RS485 cable
in a bus or line configuration. The exact details of the wiring solution will vary by
environment - the following is presented only as a guide.
Please Note
: If you already have, or are planning on getting, a PTZ capable
Swann
DVR, then using the supplied PTZ controller is optional. The PTZ system can be
controlled by the RS485 connection built into the DVR.
In the above example, three PTZ domes have been connected to the one central
controller. To achieve this wiring arrangement:
Connect the PTZ systems one at a time, and follow the instructions opposite
•
to assign each camera a separate command address.
Multiple cameras sharing a command address can cause problems when
•
implementing a system. In the best case scenario, two or more PTZ systems
sharing a command address will move synchronously, without the option to
move each camera separately. Often, a shared command address will prevent
the system from operating normally.
Once each camera has a command address defined, they can be connected
•
simultaneously.
Take the purple (+) wires, and connect all three to the +A side of the RS485 plug.
•
Repeat for white (-) wires, and connect all three to the -B side of the RS 485 plug.
•
Connect the RS485 plug to the PTZ controller.
