  When the camera is connected correctly and the serial port configured correctly you will see a message similar to the following at boot: ``APM: RunCam initialized, features 0x0077, 2-key OSD`` otherwise you will see ``APM: RunCam device not found``.
 
-- The camera must be powered and fully booted in order to accept commands.

 - Some split-style cameras support three modes - video standby, video start and picture mode. It is not possible to tell from the RunCam device protocol whether this is the type of camera in use and so this must be configured.

 .. note:: RunCam is bringing out new cameras all the time and seem to change the video controls with almost every camera, so if you are having issues - particularly with video control - try one of the other camera types for :ref:`CAM1_RC_TYPE<CAM1_RC_TYPE>`.
 
 * In order to control start and stop of video recording from a radio transmitter set a free rc channel to ``RCx_OPTION`` = 78 to enable triggering from that RC input channel. If the switch is in the low position then video recording is stopped, if in the high position then video recording is started.
