Dahua 4K IR PTZ Tested

By: Ethan Ace, Published on Aug 21, 2017

4K has made its way to IR PTZs. In this report, we examine the Dahua 6AE830VNI, a 4K PTZ with 30x optical zoom, 200m (~650') integrated IR, and 1/1.7" 4K sensor, to see how it performed in daytime and night time scenes.

Note that this report is the first in our tests of 4K IR PTZs. We will also be releasing a test report of Hikvision's 4K IR model, and a shootout comparing the two.
