Video more may offer video recording resolutions while photo mode may offer image capture size, format, compression, etc. If you simply use the MAVLink command [MAV_CMD_SET_CAMERA_MODE](../messages/common.md#MAV_CMD_SET_CAMERA_MODE), you won't have a chance to let the GCS know that. If you camera does have different parameters and/or options for [CAMERA_MODE_IMAGE](../messages/common.md#CAMERA_MODE) or [CAMERA_MODE_VIDEO](../messages/common.md#CAMERA_MODE), you may want to use this parameter (along with the proper exclusion rules) instead. The CGS will look to see if this parameter is exposed. If it is, it will use it instead of [MAV_CMD_SET_CAMERA_MODE](../messages/common.md#MAV_CMD_SET_CAMERA_MODE). If the parameter is not exposed, [MAV_CMD_SET_CAMERA_MODE](../messages/common.md#MAV_CMD_SET_CAMERA_MODE) will be used instead. See an example of a definition of `CAM_MODE` below.
