•
Default: Off
IMPORTANT
•
Select "Not use" when operating without an SD memory card.
•
Before removing the SD memory card from the camera, it is necessary to select "Not use" first. The
recorded data may be corrupted if the SD memory card is removed when "Use" is selected.
•
When an SD memory card is inserted when "Use" is selected, data will be saved in accordance with
the setting of "Save trigger".
•
After inserting the SD memory card, it is necessary to select "Use" to use the SD memory card.
•
When the image refresh interval is short, notification/recording timing or interval may become incorrect.
Notification/recording may also not be performed correctly as configured when multiple users are
receiving images. In this case, set the refresh interval longer.
•
There are limited times to overwrite on an SD memory card. When having a high frequency of
overwriting, the lifetime of the SD memory card may become shorter.
•
A lifetime of an SD memory card should be influenced by the number of the image files stored and log
savings on the SD memory card.
•
If the data writing speed goes down after data is repeatedly written on an SD memory card, we
recommend replacing the SD memory card.
•
When the setting is changed from "Off" to "On", if the remaining capacity of the SD memory card is low,
old images may be deleted in order to prepare to save new images.
