Frame buffer


I have just found about about the OpenMV cam after using an ESP32-cam. I have a question about motion detection software. I would like to know if it is possible to continuously buffer X number of seconds into the memory and then if motion is detected save this buffer and the next x seconds into a video file. I am sure this can be done but just want to check before I take the deep dive and buy a board.

I have been using pikrellcam on a raspberry pi which has these features- PiKrellCam

My second question is can I send the board into a low power state for extended periods of time (does it have an onboard rtc?). I would like to turn off the board during the day time as I will be recording nocturnal animals.

Many thanks,

I just answered your post. This is a duplicate.
