No camera control (Pan, tilt, zoom and software upgrade issues)
if the image from the camera is working but you cannot control the camera check that the video system 

can detect the camera. This can happen because the camera control is via a separate communication.

You can check the status of the attached camera from the web interface. if there is a problem you should 

see this reported on the home screen. You can also go to 

 to confirm the 

camera is detected by the codec. As you can see below the camera is not detected but the codec is 

receiving a video signal on the HDMi 1 interface.

This problem can also be confirmed in the 

 section of the web interface.

if you see that no camera is connected, there is an issue with either the camera control cable or the 

camera itself.

Far-end camera control
in order to control the camera of a far-end system in a call the system needs to have a moveable camera 

and have this option enabled. in TC6 you can set if you want to allow a far-end system to have the ability 

to control your camera. This setting is under 

, both 

Mode and SignalCapability need to be enabled for a far-end system to be able to move the camera 

and to change input sources.

Multiple cameras (daisy chaining)

if you have multiple cameras note that only the first camera in the chain is upgraded. if the cameras 

are on different software versions there is a possibility of strange behavior, for example that only zoom 

works. To upgrade the other cameras in the chain connect these directly to the codec as the first 

camera in the chain and they will be upgraded. You can reposition the cameras after this. it is possible 

to upgrade the cameras if they are connected to Ethernet.

You will see a warning under 

if there are multiple cameras attached 

that are not on the current camera software version.

You should see the message below if all of the cameras are on the correct software version.

Camera Frequency 50Hz/60Hz

You can check the camera’s frequency to ensure it matches the frequency of the lighting for the country 

you are in. You can find this under 

.

Camera not functioning – amber light
if you see your precisionHD 1080p4x Camera (CTS-pHD-1080p4XS1) in a similar state to this 

a call then you may have a problem where the software image on the camera has been corrupted.

Symptoms include:

• 

lED located on the top of the camera is on solid orange even though camera is not in a call. 

if orange lED is flashing and you have symptoms below, please contact support.

• 

Camera does not respond to controls nor does it send video.

• 

Video system does not detect the camera. Check

on the web 

interface to see if there are any problems detected.

The recovery method outlined below is available from TC5.1.5 onwards.

1.  Start the procedure by typing the using SSH to access your system.

2.  login as 

admin.

3.  Enter the command: 

systemtools camerarescue.

4.  Your SSH session is terminated and a script runs to try and recover the camera. The script 

to upgrade the camera can take up to 15 minutes to complete, but normally this should take 

around 7 minutes. 

5.  The system reboots and the camera should be recovered. Should the recovery fail, there is 

a message in the logs saying “Failed to upgrade the camera, exiting...”.

For more information, please see the field notice for precisionHD 1080p4x 

Contact support for further help should you experience this problem or if you are unable to recover 

the camera.
