Hikvision 4K IR PTZ Tested (DS-2DF8836IV-AELW)

By: Ethan Ace, Published on Nov 10, 2017

The IR PTZ trend continues, now with 4K resolution, with Hikvision releasing its DS-2DF8836IVAEL-W camera, a 4K 1/1.9" PTZ model specifying 200m IR range and 36x zoom.

We bought and tested this model to see how it performs in day and night scenes, testing:

  • Image quality
  • IR performance
  • Focus issues
  • Bandwidth
  • VMS integration

And more. See our results inside. 

Readers interested in 4K PTZs should also see our test of Dahua's 6AE830VNI 4K IR model, which will also be compared in an upcoming shootout.
