I have a couple, installed a number and then have BI as well as non-AI Dahua and other branded NVR setups, yes. My recommendation for a good AI NVR for most people (mid size business and network wide install aside) is the 5216 at this time which I started a review on and owe many updates which I will be doing now the holidays are over. Flashing with the 4.0 FW unlocks a lot of features and the HW has enough processing power to keep up.

I have to assume from other reviews I have seen of yours that you do have at least one of these AI NVR’s?
