DVTel ioimage HD Analytic Camera Tested

Author: Ethan Ace, Published on Jan 29, 2015

Four years after acquiring ioimage, DVTel has released new HD analytic cameras, with the promise of higher probability of detection and lower false alarm rates.  

Now, the question is whether these new models can fill the gap left by Avigilon's acquisition of VideoIQ.

We tested the ioimage HD camera day and night to answer the following questions:

  • How common were false alarms and from what causes?
  • What FOV width can the camera cover?
  • How well does calibration work?
  • How does it compare to Avigilon's built-in analytic cameras?
