set up by the user.
Secondary schedule is for recording outside of the primary schedule. The secondary schedule provides options to
record without a specified date or time.
There are three modes in the secondary schedule: Disable, Event mode, and Continuous mode. If event mode is selected
in the secondary schedule, the camera will record whenever an event is triggered. If continuous mode is selected, the
camera will begin recording continuously after scheduling settings are saved. These two modes are the same as the
primary schedule. Please refer to the previous section for more detail.
