Pan/Tilt/Zoom (PTZ) Cameras 17
Pan/Tilt/Zoom (PTZ) cameras are specialty cameras that move according to commands given by
the recorder. You can move PTZ cameras manually using the recorder’s on-screen display, or cre-
ate preset locations and patterns for the camera to follow automatically.
17.1 Connecting PTZ Cameras to the Recorder
Lorex HD PTZ cameras connect to your recorder just like any other camera with no need to run
special wiring — these cameras can accept PTZ commands directly through the video cable.
If you are using a standard definition PTZ camera, you will need to run the camera’s RS485 ca-
bling to the recorder in order to send PTZ commands.
To connect standard definition PTZ cameras:
STEP 1: Physical connection
1. Connect the BNC video cable to one of the video inputs on the recorder.
2. Connect the RS485 cables. Connect the
A (TX+) cable to the positive (+) terminal , and con-
nect the B (TX–) cable to the negative (–) terminal .
3. Connect the PTZ camera’s power adapter to a power outlet.
CAUTION
When the PTZ camera powers on, it will perform an initial diagnostics check. The camera will move around
during this process, so ensure the camera module is not resting against another object or surface.
