Dahua Integrated IR PTZ Tested

Author: Ethan Ace, Published on Jun 04, 2014

Integrated IR cameras are growing rapidly in popularity, as they help solve a key surveillance problem - poor low light imaging.

However, integrated IR is rarely offered inside PTZs. Indeed, no major Western manufacturer offers an integrated IR PTZ. Recently, though, a number of Asian manufacturers have started to offer these models.

As part of our Dahua HD CVI test, we paid ~$450 for a 720p HD, 20x optical zoom, integrated IR PTZ, rated for 100m IR range. That is quite a price point, considering many Western manufacturers fixed IR IP cameras are more expensive than that.

In this report, we share our test findings of this integrated IR PTZ vs an Axis Q series PTZ.

The image below shows, left to right, the IR PTZ itself, the IR LED pattern and an excerpt of a person being tracked by the IR PTZ:

We tested the PTZs day and night at distance up to 450' / 137 meters to see how performance varied and the tradeoffs amongst the cameras.
