3.1. Camera States

The feature CameraState indicates der current state of the camera.

The camera has 4 states:

•

IDLE

the camera is in IDLE state

•

LIVE

the camera is streaming live frames from the camera to the host

•

RECORDING

the camera is in recording mode. Recorded frames will be stored in the cameras internal buffer. If
LIVE streaming was enabled when recording starts, a live image stream is send to the host while
recording is running.

•

STREAMING

the camera is streams recorded frame data from the cameras internal buffer to the host.

The accessibility of camera features depends on the current camera state. The table below shows
this dependencies.
