CONNECTING AND CONTROLLING PTZ CAMERAS
5. CONNECTING AND CONTROLLING PTZ CAMERAS
NDR-EA2104, NDR-EA2208 and NDR-EA2416 feature the possibility of remote controlling of up to
4/8/16 cameras via the RS-485 bus, cascade connection. Cameras may be either speed domes, classic
cameras with optical/digital zoom or other cameras with proper protocols implemented. The control
over cameras is performed via buttons located on the front panel of the DVR, IR remote controller,
USB mouse, IE web browser, E-Viewer software and iMon2 software. To ensure the proper operation
of control protocols, please assign unique address (in a system) to each of the system cameras.
The DVR supports various control protocols, e.g. N-Control, Pelco-D, Pelco-P and others.
Note:
All the cameras in one system should have the same control protocol and transmission speed set
in their menus (check the user’s manual of the camera for more details).
The description presented below is valid for Novus CAMA-III cameras. To connect cameras of other
manufacturers, please contact respective tech support and/or consult the user’s manuals for each of the
cameras in question.
Note:
For speed dome camera control, RS-232 port may be used. RS-232 - RS-485 converter should
be used under such circumstances, e.g. NVPT-001RSC. Such connection is used when a
necessity of connecting a keyboard and speed dome cameras to one DVR arises.
Note:
Pelco-D(N) protocol is a special modification of the Pelco-D protocol that enables PTZ control
for certain Novus cameras with RS-485 interface. Setting the minimum and maximum speed
values in the Speed column is strongly not recommended when using this protocol.
Furthermore, Preset96 function (former “ESC” command) is now assigned to Preset16,
effectively replacing it (i.e. Preset16 is now the proper ESC command).
5.1 Connecting NOVUS PTZ cameras.
Speed dome cameras are cascade connected using UTP cat. 5. Cameras are connected to a port marked
as
RS-485.
Maximum length of the wire shouldn’t exceed 1200m.
Telemetry junctions are located at the rear of the device, available as a terminal block. To ease the
connecting process, plugging the socket out of the terminal is possible. Please connect the wires
between the DVR and cameras in a way described below:
Detailed information regarding PTZ camera control are presented in chapters 3.2.1 (
Cameras
) and
3.2.5 (
RS232/RS485
).
Button functions, used for PTZ camera control, are further described in chapter 2.4 and 2.6 of this
manual
(Controlling via IR remote controller
).
