Recording methods

The following table shows the recording methods.
Recording method
File saving trigger only
Recording startup trigger + file saving trigger
File saving trigger only
This is a method for sampling, receiving, and accumulating data (devices, labels, and video data) after the operating status of
the recording function switches to 'operating.'
When a file saving trigger is satisfied, data accumulated during a period before and after the trigger is satisfied
(Page 27 File saving trigger)
A recording file is saved after a saving period elapses. Data accumulation stops during file saving and restarts after its
completion.
*1 For video data, data reception and accumulation start when the operating status of the recording function switches to 'operating,' the
communication with a network camera is established, and video data is delivered from the network camera.
*2 A period before or after a trigger is satisfied (saving period before trigger/saving period after trigger) can be set in the saving period
setting in the recording setting.
When setting the saving period after trigger to '0' seconds, a recording file is saved when a file saving trigger is satisfied.

*3 For video data, data accumulated approximately one second before the saving period may also be saved.

1.1 Recording Function
Description
Data (devices, labels, and video data) after the
operating status of the recording function
switches to 'operating' can be sampled, received,
and accumulated.
Devices and labels after the operating status of
the recording function switches to 'operating' and
a recording startup trigger is satisfied can be
accumulated for a specified period.

Purpose
Select this method to check the status of a device
before and after an error occurs in the device when
the error occurrence timing is clear. (By specifying
an error occurrence as a file saving trigger, the
operating status of a device before and after the
error occurs can be checked.)
Select this method when the timing is different
between when an error occurs and when it is
detected, such as when an error occurs while a
device is operating at regular intervals and it does
not start operating at the next operation timing. (By
using a recording startup trigger to specify a timing
to start accumulating devices and labels and by
including the timing when an error occurs in an
accumulation period, the status of a device when it
last operated can be checked.)
