The storage of video data is managed by the ibaCapture Server. The service is started automatically after booting the system.

For every camera, a fixed memory segment is allocated on the hard drive. This is done to avoid storage fragmentation as far as possible and to ensure stable storage performance. The exact procedure to configure ibaCapture Server can be found in the chapter Configuration of ibaCapture Server.

The cameras' memory segments are built in ring buffer architecture. Within the ring buffer, a configurable percentage of the allocated space can hold protected video. Example:

The whole area is generally used for continuous video recording. Continuous recording of the configured camera(s) starts immediately after system startup of ibaCapture Server. The video recording will be linked to the measured data as soon as the recording of ibaPDA is started.

The protected area is used to store video sequences which should be saved for a longer period. Video data for protected video is stored in the ring buffer and then marked as “protected”. This can happen interactively or through the video trigger feature in ibaPDA. Video triggers can be configured in the data storage settings of ibaPDA with multiple start and stop conditions. These start and stop conditions enable the specific recording of events and reduce the memory requirements of the protected memory segments of each camera.

The video sequences controlled by video triggers are called triggered recordings.

When continuously recording video data, the protected areas are skipped.

When the unprotected or protected video storage has been completely written, the oldest sequences lose their protection and can be overwritten by newer entries due to the ring buffer architecture.
