I've seen erratic camera/remote behaviour before like this when the batteries get too low, or the remote is being used too far away from the device and is set to low power mode.
Check the dip switch in the battery compartment is set to the high position and make sure you have fresh batteries in it and see if that helps.
The other thing to check would be that the camera control cable is connected firmly at both ends - try unplugging it and re-plugging it a couple of times in case the connectors have oxidized a bit.
Note: Your question would be better placed in the TelePresence section of the forums where these devices are more actively discussed than in the Other Collaboration section you've posted in - I'd suggest, if the above hasn't answered your query, that you move your discussion over there.
