Industrial Event Camera
Web Interface
•
Manual selection of sensitivity / gain (ISO / Gain)
•
Automatic ISO selection also possible with fixed shutter time
•
The automatic ISO setting only works in the range 100 ... 800
Note
To capture moving objects without motion blur, the exposure time can be fixed at a
correspondingly short value. Stronger illumination may be required.
At speeds above approx. 1 m/s, the image is significantly distorted by the rolling shutter effect.
It must be checked on an application-specific basis whether this is a problem.
Extended Recording Time
The recorded files can be very large. The Pre-event recording time is limited to 150 MB, the
actual Pre-event recording time will be shorter when this size is reached. The total file size is
limited to 500 MB, the actual Post-event recording time will be shorter when this file size is
reached.

•
Default setting for pre- and post-trigger time is max. 60 seconds
•
Pre- and Post-trigger can be extended up to 900 seconds with the expert setting.
•
The pre-trigger has a maximum file size of 150 MB. The video is correspondingly shorter if
the file size is not enough for the required time.
•
The total size of the video is limited to 500 MB. Recording ends when this limit is reached.
Note
The video size depends on the following factors:
•
Image content (static / dynamic) due to video compression
•
Brightness change
•
Resolution and quality setting (changeable in the user interface)
•
— Rough values: 0.1 ... 1.5 MB/s
Example
The data rate can be set according to the requirement:
•
Recording: e.g. 2 min
•
File size: e.g. 60 MB
•
— 60 MB / 120 s = 0.5 MB/s
