On a clear day this would definitely help however where I live in the UK there is frequent cloud cover. As the sun passes in and out of the clouds the light levels end up changing a surprising amount, causing frequent exposure flashes on the camera which essentially voids the calibration. In trying to achieve very high sensitivity I could not really make any kind of rolling calibration work sadly

There is a hard limit of 100 saved images per capture session so no risk of blowing up your phone . Yeah I would like to add a settings page for people who know what they are looking for. That is a good idea thanks!

I wasn't able to test much on iOS unfortunately. I know on Windows 10 if one browser is already using the camera it will say camera unavailable when launching a different browser. I am not sure if it is related to this?

Cool I will look into this. Thank you

haha I have experienced lots of these problems while testing and tried my best to build in logic to detect 'real' motion. However since I wanted it sensitive enough to detect things like a slow moving woodlouse there will always be false detections unfortunately. One of my tests I couldn't work out why tin foil was flagging as motion, turned out it was the moon outside the window hitting it at different angles during the night!

It will use whichever camera the browser has configured as it's default. You may be able to change this in your browser settings

Yeah the original image is retained, when you open the image full size there is a button in the modal that lets you toggle the motion highlights on and off. The downloaded image will also just be the original as captured by the camera
