This is a basic guide for setting up "Artificial Intelligence" for human and vehicle detection.
For this you will need - a Dahua Network Video Recorder (NVR) with IVS (NVR4.0) and Dahua Camera with IVS.
Each camera will use it's processing power to detect events and tag them in your recorder.
With this setup you will be able to search through your footage and find events (footage) specific to humans and vehicles.
