It seems that dahua's new tracker is really great- smooth intelligent tracking. I was pretty blown away by the menu for it. However, you can see in vec's clip that it locks onto a target so well that it may ignore anything else that may actually be more important at the time. For instance, it locks onto tracking a vehicle through a parking lot but it's not the vehicle being stolen at the time. Lost opportunity, considering well placed and calculated fixed cameras wouldn't miss a thing. I love dahua ptz's and this tracker is damn sweet. But you really have to balance that out with realistic expectations for every single second of video evidence gathering. There is nothing more frustrating than farming out critical evidence only to see you missed it- not just because the resolution detail wasn't good, but because the freakin camera coverage wasn't there at all. PTZ's can be their own worst enemy. In crtical coverage situations, a ptz, or even better such as a tracking ptz, is always best used as support for fixed camera full coverage. That truly gives you the best odds at not missing the gotcha.
