Pre-alarm and post-alarm recording

Pre-alarm and post-alarm recording involve recording data according to a selected ratio in the camera’s internal memory. The default ratio is pre-alarm = 0 / post-alarm = 10. When an alarm is detected in this condition, only post-alarm images are recorded in the camera’s internal memory.

Post-alarm recording is the recording of alarm data after an alarm has been detected by an external sensor or motion detector. When an alarm is detected, the alarm data is recorded into the internal memory according to the ratio selected. If the ratio is 0/10, all of the available memory space is devoted to post-alarm recording.

Pre-alarm recording sequentially records alarm images from immediately before the alarm was detected according to the ratio selected. When an alarm is detected, images from before the alarm that fall within the amount specified by the ratio selected are recorded in the pre-alarm area of the internal memory.

For example, if the alarm recording area of the internal memory is set to a ratio of 3/7, 30% of the available area is devoted to recording images from immediately before the alarm is detected. Actual alarm images are then recorded in the remaining 70%, and the pre-alarm and post-alarm recordings are treated as a single alarm event.

When alarm images are played back, the images can be viewed continuously starting from the first images recorded immediately before the alarm was detected. The alarm recording area ratio is an important point for consideration when making settings.
