As I understand it, Sighthound is tuned to receive and process 10 fps. Anyhting more is ignored but I have my cameras feedling more (20, typically) just to add a bit of margin so Sighthound always will get the 10 it expects.
Saved files, though, are less than 10 fps, and it varies. Why is that? Could there be a bottleneck (CPU, hard drive speed) causing this?
