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 Ethernet cable.
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.
To connect Lorex PTZ cameras:
1. Connect the Ethernet cable to one of the video inputs on the recorder.
2.
(OPTIONAL) Connect the PTZ camera’s power adapter to a power outlet.
CAUTION
Most PTZ cameras have a higher power requirement than fixed cameras. If you are planning to connect more
than one PTZ camera to the system, check the power requirement in your PTZ camera’s documentation to en-
sure you remain within the total PoE power output of the recorder (80W). Connecting the included power
adapter to your PTZ camera as shown above will force it to draw power from the wall outlet rather than the re-
corder’s PoE switch.
