Testing AHD 2014

Author: Ethan Ace, Published on Sep 24, 2014

This is where the innovation is at.

During Essen and days before ASIS, IPVM is leading with a test of an analog (HD) camera, reflecting both how bad the big names are doing and the key trend we see accelerating.

A number of non IP HD offerings are emerging (for background see: HD Analog vs IP Tutorial and HD-SDI Vs HD-CVI Vs HD-TVI Vs HDcctv?)

Earlier this year, we tested Dahua HDCVI and Testing Q-See Analog HD Kit, which generated a great member response.

Now, we are testing an emerging rival, simply named "AHD" which is increasingly the go to option for smaller Asian manufacturers.

We bought three AHD cameras and two HD DVRs for a grand total of less than $250 to find out.

We tested these AHD models against competitive HDCVI and low cost HD IP cameras to see how they compare, answering these questions:

  • How does image quality compare to HD IP and HDCVI cameras?
  • How does analog video support work?
  • Was latency an issue?
  • Were cameras and DVRs from different manufacturers truly compatible?
  • How well does Analog HD perform over long or low-grade cables?
