Processing time
Calculation of total event processing time:
Time for image processing
+ image or video compression
+ zip container
+ writing on SD card or FTP transmission
= Total event processing time
NOTE
Thumb rule:
2 * event time = total event processing time

Example: Video with 1080p @ 15 fps, 10 s before trigger and 5 s after trigger signal:
Processing time = 1.1 x (10 s+5 s) = 16.5 s
Additionally, 1s per 15 MB event data has to be added for zip container compression.
