Testing Avigilon's Image Enhancement

Author: Ethan Ace, Published on May 27, 2013

Typically, VMS software displays video 'as is'. While there may be basic brightness, contrast and saturation controls, those require manual adjustment with significant tradeoffs.

By contrast, Avigilon's VMS has an interesting feature called 'Display Adjustments' that automatically adjusts the quality of video displayed. This is what the control looks like:

That noted, even without pulling this up, the software continuously re-adjusts on its own. Additionally, it works on any camera connected to Avigilon's VMS, not just their own.

Since this feature is rare, we wanted to understand what practical benefit it delivered so we did tests with a variety of cameras including budget, low light optimized, WDR, mid range and thermal to better understand when and how much of a difference this makes.
