Dahua HDCVI 2.0 Tested

Author: Ethan Ace, Published on Nov 17, 2014

A strong initial reception but can it repeat?

Dahua's initial HDCVI analog HD offering, with its super low cost and HD resolution, was extremely well received (see IPVM's HDCVI test results).

Now less than a year later, Dahua is releasing HDCVI 2.0 claiming improved low light, WDR, and new motorized zoom and autofocus functions.

We tested two 1080p bullet cameras, the motorized zoom HAC-HFW2220RN-Z and the compact HAC-HFW2220-SN, along with the HCVR7216S, a "tribrid" recorder supporting HDCVI, SD analog and IP cameras.

Can Dahua repeat or will this be a dissapointment?

In this test we examine:

  • How do these compare to IP cameras from big competitors like Axis, Hikvision and Samsung?
  • How did low light performance compare to past Dahua models?
  • How much has WDR performance improved?
  • How well does this new tribrid DVR support each type of camera?
