I'll put a little observation on this for a few nights. The headline time was on the fireball camera for the brightest Perseid.
The maximum night was partly clear, but the humidity ruined the visibility of the camera window. As late as 10pm there was a downpour and a camera next to the wet foliage on the other side of the lake.
At 13/14 night I also put the brightest fireball camera in the 2 m sum shot (0230 - 0232). At the time, there was also a digital camera Canon EOS 6D shooting 28mm, F1.8 lens mode almost the same area. This came to the far left of the image so that only the beginning was visible and the end was outside the image. I attach a cropped, otherwise unprocessed image from it.
