Panasonic 32MP Multi Imager Camera Tested (WV-X8570N)

By Ethan Ace and Rob Kilpatrick, Published May 16, 2019, 10:16am EDT

Panasonic has released their first multi imager models including the 32MP (4x4K) WV-X8570N, claiming "Extreme image quality for evidence capturing under challenging conditions", "outstanding low light", and "Super Dynamic" performance.

We bought and tested the WV-X8570N to see how it performs, examining:

  • How does it perform in full light (~300 lux), low light, ~(2 lux), and dark scenes (~0.01 lux)?
  • How flexible is imager positioning?
  • How does it compare in size to competitive multi-imagers?
  • How do H.265 and H.264 day and night bitrates compare?
  • How well does it integrate to third party VMSes (Avigilon, Exacq, Genetec, Milestone and NxWitness)?
  • How many VMS licenses does it use?

This is the latest in a series of new repositionable multi imager testing. Readers should also see our tests of the Axis P3717-PLE, Hanwha's PNM-9000VQ, Hikvision PanoVu 20MP, and Dahua's Multi-Flex 4x2MP. Coming up we plan to test Avigilon's H4 multi sensor and Vivotek's MA9321-EHTV as well as a shootout of all these recent repositionable models.

There is noticeable overlap between all imagers...

is it even theoretically possible for that camera to have a config with no overlap at all?  maybe 3 full up tilt with 1 down the hatch?

i am very happy to see IPVM testing Panasonic Cameras. I do like the over lap when using all four imagers in a 270 degree setup. I would like to see how it does with lens four turn straight down ans the other three adjusted to cover the 270 degrees of coverage and see how much over lap there is. The report and test is very good and covered every question I had about the camera. Best testing of cameras in real world period!

Update:

Added section explaining VMD performance. The Panasonic WV-X8570N does not include intrusion detection, we tested the performance of VMD and the camera alerted on the simplest of false alarm sources in the scene, such as blinking lights from switch ports.
