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: 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: over 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: over 2 years ago

You can go around some of the extra processing by using other camera apps, for example "Open Camera". It can even shoot RAW photos, so that the least amount of processing is applied to the image. Unfortunately, you can't disable all of the processing, because some of it happen on the hardware, or in the camera's kernel module. https://opencamera.org.uk/. - Source: Hacker News / over 1 year ago
