Hello, 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 i…

OK do you have plans to implement a frame buffer in the driver soon? I’m recording bats and they move in and out of shot in much less than a second so any lag in the motion processing means they are missed.

Sorry about the duplicate post. I also asked about whether the board has an RTC?

The microcontroller has an RTC, however there’s no backup battery, so you’ll need to keep power on all the time. The RTC still functions in low-power modes. There’s no plan to implement recording in memory for now, but if it ever gets implemented it will only be possible on the H7+ with SDRAM. EDIT…

I’ve done some tests with a pir but no success. Thanks though. Probably not the one for me at the mo,

Hi, Tracking two objects(circle shape) within the field of frame buffer. But the problem is when I try to center one object then the other object also comes to the field. So the device is confused to center the object. My question is when multiple objects in the frame buffer(scope of the camera), I…

Hi, you need to explain more clearly what the problem is… if you have two objects that look similar then you need some way to distinguish them. Can you give a picture of the issue?

Hi, Please see the attached file for you reference. here frame buffer have two circle shape objects, when i try to center the object 1 to the frame then object 2 also there at frame see at attached file. in this case i confused to know the object 1 from the find_circles() library to center the obje…

Hi, Please find attached file for your reference [image (1).png]

Is there any way to tell the difference between the two objects? If you want to choose one over the other you need to have some criteria for that. Otherwise, they both are valid to center on.

Hi, I’m just wondering if frame buffers were ever implemented in the h7+? Or plans in the future? Thanks, Sam
