Testing Dahua HDCVI Encoder With VMSes

Author: Ethan Ace, Published on May 14, 2015

HD Analog cameras have incredibly low prices for true HD video.

But HD analog recorders are pretty simplistic and underwhelming.

Moreover, many want to use HD analog cameras with their established, higher end VMS software systems.

Now, Dahua has released 4, 8, and 16 channel 1080p HD-CVI encoders, which should make it easier to connect HD-CVI cameras to VMS software.

We tested the Dahua NVS0404HDC-A, a four channel model, with multiple fixed and PTZ cameras, attempting to integrate with Avigilon, Exacq, Genetec and Milestone VMSes:

  • Did all HDCVI cameras, 720p, 1080p, from multiple manufacturers, work without issue?
  • Were there issues streaming all channels at maximum frame rate?
  • What features worked and did not with each VMS?
