Film In The Past

My project is a camera controlled by a raspberry pi that is attached to a hat. This camera is constantly on, it films everything, but records only the last 7 seconds of videos. Let's take an example, imagine you are walking in the street and you see a meteorite in the sky, obviously you don't have time to take your phone to film it, fortunatly after the passage of the meteorite, you just have to press a button on the hat and the camera will record the last 7 seconds. Then you can download the video from an application on your phone.The code is written in python and it uses OpenCV. The system is powered with an external battery of 5000 mAh.The raspberry Pi is used as a wireless access point. Thanks to the application FTPManager (https://apps.apple.com/fr/app/ftpmanager-ftp-sftp-client/id525959186) we can connect to the raspberry from a phone to recover the video.
