I have deployed about 50 of these cameras, one of the best anpr cameras on the market especially for the price.
edit - one knock is making camera adjustments with the teeth style mount absolutely sucks
i have the autotrack firmware for this series let me know if you need it, dahua removed the autotrack due to it eating into the sales of the 5 series pro ai ptz's.
10-2020 firmware was just released, fixed everything I previously had an issue with (AI Preview playback) but also completely improved the metadata functions on this NVR, this thing is reading license plates like a complete animal!
