Yah, that’s what I expected. Then when I tried writing down what I wanted it occurred to me that if I could FTP images with the plate and time in the file name it would work. If only Dahua would implement macros like BI that can be used in file names.You are better off staying with your Z12E cameras and BI or buying this camera and the associated NVR to do what you want, and even then it probably can't check all the boxes.
Next, what can I get from my old NVR5216 4KS2? Can it make use of any of the smarts from this camera? I don’t like the interface and switched to BI, but would it be useful running in parallel? Can the dumb NVR search based on plates?
I am loath to run an AI program on the BI computer for fear of overloading it. It seems that whenever the CPU gets near 100% BI takes a dump which requires restarting BI. I have not had nearly the problem since switching to sub feeds for all higher resolution cameras.
