How long is the elapsed time between updates?

4 days ago I installed an outdoor camera which immediately is updated to firmware v1.7.3.312 but I learned that the latest version is v1.10. I tried pausing motion detection for 12+ hours, but until today the firmware is still v1.7.3.312  So when can I expect it to be updated (again) to v1.10?

As a note: I have two other outdoor cameras already on firmware v1.10.
