5. CONNECTING AND CONTROLLING PTZ CAMERAS
DVR features the possibility of remote controlling of up to 4 cameras via the RS-485 bus, cascade
connection. Cameras may be either of speed dome type, classic cameras with optical/digital zoom or
other cameras with proper protocols implemented. The control over cameras is performed via IR
remote controller, USB mouse, IE web browser or E-Viewer software. To ensure the proper operation
of control protocols, please assign unique (in the system) address to each of the system cameras.
The DVR is able to cooperate with 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-II cameras. To connect cameras of other
manufacturers, please consult the tech support and the user’s manual for each of the cameras.
Note: For speed dome camera control, RS-232 port may be used. In such a case, RS-232 - RS-485
converter should be used, e.g. NVPT-001RSC. Such connection is used, when a necessity of
connecting a keyboard and speed dome cameras to one DVR arises.
