What did you observe was the bit-rate in the 20MP JPEG mode when it was delivering those images to the the Web UI or Milestone?

Did it stay under the 32Mb/s system cap via nerfed frame-rate?

The 32Mb/s is for H.264.

There's different controls for MJPEG, screencapped below:

The bandwidth consumption for MJPEG 20MP / 2.5fps ranged from 30 - 50fps depending on the JPEG level selected.

Would be great to see these tests with headlights.. how do you think it would go getting number plates?

John, how did you get the camera to integrate into Exacq, since it's still currently not on their supported camera list?

The H.264 streams worked fine in Exacq when we tested it, using the Sony driver. The MJPEG stream didn't work at all.

What were your settings when calculating the bandwidth? FPS?

Also, comparing your WDR shot in the garage, my picture for the panasonic comes up as completely black. Is that really what came from the shot?

Bandwidth measurements were at 10 FPS, 10 GOP. All the cameras except Sony were set to ~30 quantization except for Sony, which had no fixed compression levels (which we talk about above).

And yes, the Panasonic was completely black in the area beside the door. We saw that in our original test of it, as well. It's excellent against backlight, poor in darker areas.

Does anyone have a POC for Sony to get a demo camera. I tried the main office they needed to speak to my manager and or attorney. I'm on east coast. Thanks in advance for assistance
