Haven, available either on F-Droid or Google Play. Source: 11 months ago

Haven might be what you are looking for. It can activate sound and video recording upon noise, light and vibration. It is in the IzzyOnDroid Repo or has its own repo. Check the project page: Https://guardianproject.github.io/haven. Source: 11 months ago

Haven is open source. Last updated 2019, but works. https://guardianproject.github.io/haven/. - Source: Hacker News / about 1 year ago

You could retire it to a personal surveillance camera with haven (needs a sim for registration though). With root, you could even set a charging limit so the battery doesn't die. Source: about 2 years ago

For budget option, you can install Haven on an old phone and it would record/report audio, visual and movement you need to monitor. Source: about 2 years ago

Found these guys but doesn't look like it's for sale yet and I am thinking there has to be someone working on a cheaper home use solution - https://sunflower-labs.com/. Source: 12 months ago

Https://sunflower-labs.com/ It exists and is supposed to be available this year, but per their FAQ it will be astronomically expensive (they don't even sell them, they rent at $3k/month!). Source: almost 2 years ago

Has existed for several years, but cost is not yet consumer accessible. $10k last I checked. https://sunflower-labs.com. Source: almost 2 years ago
