I never used their app, but I have a Yi camera. There are several open source firmwares for them that provide many more features than stock. I feed my cameras into Frigate, which isn’t particularly simple to configure, but gives you a great open source DVR.

I don’t really like the Yi camera actually. I’ve had much better luck with Amcrest.

I love all strava’s social elements, but it has just gotten worse and worse over time. We really need a federated alternative. I’ve been toying with concepts for a while, even made a bridge from Garmin to mastodon API, but the long term concern for me is that Garmin seems to be picky with official API access so it would be difficult for individual servers to import data from there or other sources.
