7.4.2 PTZ
7.4.2 (a) Settings
Configure settings on your DVR to control a PTZ enabled camera.
Channel: Choose the channel with a PTZ enabled camera. Not all cameras are
PTZ enabled.
Protocol: Is the type of PTZ data protocol that the DVR will use to control the PTZ
cameras. It is necessary to change this only for third party PTZ Camera compatibility.
The Default Value for Night Owl’s PTZ camera is PelcoD.
Baudrate: Indicate the frequency of communication to the PTZ camera. We
recommend leaving the default setting which is 9600.
DataBit: Select the amount of data to send during each transmission. 8 bits is
standard for all modern data transmissions.
StopBit: Select the amount of extra data to send each time a direction is sent to
the camera. The stopbit serves as a buffer between commands and should be 1
(by default) when utilizing Night Owl’s AHD PTZ camera.
Parity: Detects corrupt commands sent to and from the PTZ camera. This should
generally be left Disabled.
Cruise: Enable or Disable the PTZ cruise function, which allows the camera to
automatically scan the area periodically with no manual input.
Address: Enter an ID number for the PTZ camera, greater than 0. If using multiple
PTZ cameras, ID numbers cannot be the same.
