NCNN

Detects objects, faces and license plates in the video of your cameras. It runs on the server's processor or, when one is present, on a graphics card that supports Vulkan.

What it does

• Detects people, vehicles and animals
• Detects faces and recognizes known people
• Detects license plates and reads their text
• Uses a graphics card with Vulkan when one is present, otherwise the processor
• Follows the confidence values from the camera's detection settings
• Downloads its models itself

What you need

• For faster detection, a graphics card with Vulkan support; without one the plugin runs on the processor
• For names on faces, this plugin must be selected as "Face Recognition" for each camera: camera settings, "Plugins", "Detections"

Settings

• Face recognition model: shared by all cameras. After a change the saved faces are recalculated
• Use Vulkan (GPU): when on, the models run on the graphics card through Vulkan if it is available; otherwise on the processor
• Vulkan device: which graphics card is used on systems with several; "Auto" leaves the choice to the system
• Active hardware: shows where the models are running
• Download models again: deletes the downloaded models and downloads the current ones
• Reset settings: puts all plugin settings back to their defaults
• Per camera, in the groups "Object detection", "Face detection" and "License plates": Model, Detection model and OCR model. "Default" follows the recommended model
