Sure, but with this change it’s becoming harder to see the advantage of VMware over hyperV with full lintegration to azure, and azure stack edge. A single interface to manage cloud and on prem that includes monitoring etc.
Sunk cost or not, with this change the companies need to move anyway so the immediate question is why not all the way? but I might be wrong.
A lot of the more modern NVR systems can be accessed from the internet. So you can use these.
Synology has security station on their NAS systems (although there is some licensing nowadays depending on model and number of cameras.
Ubiquity also offers local storage for their system, that also offers a bellcam (like ring) and different in and outdoor camera models.
Good luck!
