Huh. The cameras in their video are some of Avigilon's demo site cameras.

Curious why they use Avigilon cameras, fact is that if the dynamic range is not captured then it cannot be shown! Looks that they do some video processing as well but if the dynamic range is not there, there is not much the tool can do without raw material.

For monitoring purposes, I could see this work. However, for evidential purposes, I would not think this would be acceptable due to the fact this is software and not a filter changing the data. Once software changes data, then the picture is not 100% official even though it looks more like the real thing. The-hair-above-average person does this with simple photo software to the more advanced Photoshop software when dealing with personal photos. In these programs, it is known as an "Effect". It is not live video software, however, I'm just pointing out it is a software effect. When it comes to software editing of images, if we allow this, then we allow the possibility of “Photoshoped” evidence in our judicial system.
This is something you should ask the company and others what they think is acceptable software editing when it comes to evidence. Where should the line be drawn?

We did a short test. Not impressive - extreme latency, questionable, if any image improvements:

Funny that Avigilon is mentioned since Avigilon has a similar feature built in of "Display Adjustmetns" and I would say any other respectable VMS too.
Avigilon also increases or decreases the amount of light in the picture when you digitally zoom in and out of dark places. I think Lentix does a better job but the price is not proportional.

Is it me or this simple histogram curve manipulation, like playing with the Levels dialog in Photoshop? There is usually "hidden" information in the dark areas of most images/video that becomes easier to see once you crank the gamma levels.
The demo videos underscore the need for video enhancement but $1000 MSRP per channel for histogram manipulation seems rather high. If I remember correctly from my days at StarDot, they had histogram correction in their image processing FPGA but I don't think precise control parameters were offered to the user. The point is realtime histogram correction / manipulation can also occur at the edge.
