Serial Port Mode Configuration
The RS485 serial port is used for data exchange with the third-party device. Serial port settings on the
camera should be consistent with that of the connected third-party device.
NOTE!
This function is not supported by some models, please see the actual model for details.
The actual displayed Web interface may vary with the device model.
PTZ control
To control a PTZ camera through a third-party device, you need to set
Port Mode
to
PTZ Control
.
By sending PELCO-D compliant PTZ control commands through the RS485 port, you can control the PTZ
camera without using the PTZ control panel.

, and then click the
Serial Port
tab.

Select
PTZ Control
from the
Port Mode
drop-down list. The following table describes some major
parameters.
Parameter
Description
PTZ Protocol
Set the PTZ protocol that the channel supports.
Note:
You can set this parameter only when
Port Mode
is set to
PTZ Control
.
When
PTZ Protocol
is set to
INTERNAL-PTZ
, the camera can connect to the external PTZ
without using the serial port (serial port parameters are grayed out). In this case, you
only need to connect the zoom and focus interfaces of the camera to the lens, and then
you can operate the PTZ like an internal PTZ.
PTZ Mode
Built-in PTZ Priority: When this option is selected, the camera first tries to control the
PTZ (for example, to zoom or focus) by itself instead of through the external PTZ. For
operations that the camera cannot accomplish by itself, the camera uses the external
PTZ.
External PTZ Priority: The camera first tries to control the PTZ through the PTZ
connected through the serial port.
