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?

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?

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?

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
