6.1 Permanent Recording of Camera Images
During a measurement with the data logger, the HostCAMF44 makes it possible to record images
permanently and to transmit them to the data logger. For this,
»
Image resolution (see chap.3.3) and frame rate (see chap. 3.5) have to be set low enough
»
The action “Pretrigger” must be deactivated resp. set to 0.
»
The action “While the rule is active” must be active (see chap. 3.5).
»
The action “Post-event time” must be deactivated resp. set to 0.
The following example shows how a permanent recording with HostCAMF44 with two sensor units in
connection with the G.i.N. data logger is possible:

The data logger triggers the camera immediately when it comes online (“
HostCameraStatus.1 = 1
”) and
keeps the trigger active until shutdown.
»
If the camera is not connected anymore (“
HostCameraStatus.1 = 0
”), the data logger resets the trigger
with “
HostCameraTrigger = Off
”. As soon as the camera is online, the data logger triggers it again. This
functionality helps to transmit the camera data in the case of a short interruption.
»
For every measurement (without interruption), a zip file with the transmitted images is stored in the root
directory of the external storage medium.
»
The camera trigger is set and reset with key1
