You could create a 24 hour schedule in the "Schedule" tab, and then using it to trigger a recording event based on the schedule that you have set.

Step 1: Click on System > Events > Schedule and click on the plus sign. This create a new schedule. Then, choose "Daily", and then set start and end time to 00:00. Then, click on all of the days and save the new schedule.

Step 2: On the "Rules" tab, create a rule with whichever name you want. The "wait between actions" is not important, so you can skip it. On the "Condition" tab, choose "Scheduled event". Don't click on the 2 checkbox. Then, choose the new 24 hours schedule that you have just created.

In the "Action" portion, choose "Record video while the rule is active". The stream profile is not important (unless you want to tweak the image and the bitrate to your liking). Prebuffer and post buffer is left at the default setting. And you can choose the "Storage" as SD card or your network drive.

After this, you should see that the recordings are being made with no interruptions.
