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

By: Ethan Ace and Rob Kilpatrick, Published on May 16, 2019

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.
