Anyone know of any software I can override the Google Nest Doorbell with ? One that’s maybe open source ? I know I could just buy another camera but I was hoping to keep using this one with safer software

Nest and Eero/echo are two brands I wouldn’t trust even if jailbroken. They’ve both been shown to contain more hardware than originally announced after some third party tear downs.

I second the point, getting rid of it is safer for everyone

Any recommendations for an alternative?

If you have the ability, UniFi makes a good doorbell that keeps recordings on a central controller. I have one at home. Also can do people and package notifications to your phone. The downside is you also need a central controller, but if you have a spare PC or something, you can install it there. Alternatively, UniFi sells dedicated controller hardware that can also be used with their WiFi and other product lines. Hardware costs money but software is free.

There are likely other doorbells that record to a local micro sd card, but I have no experience with those.
