Adding a Camera

Cameras are added where they are first needed: inside a camera condition. Three connection methods are supported.

Camera Source	Input
CSI/USB	Select from the cameras connected directly to the controller. This covers Raspberry Pi camera modules and USB webcams.
ONVIF	Search the network and select the camera. If it is not found, enter its IP address.
RTSP	The stream address, plus a username and password if the camera requires them. The `rtsp://` prefix can be omitted.

Note IP cameras must be on the same network as the controller. The user's location does not matter; monitoring through the app works from anywhere.

Camera settings: regions of interest vs. detection zones

Camera settings open from the gear icon on the camera panel. They are available while stopped; while running, the same spot shows the fullscreen button.

Camera Name	Used everywhere the camera is referenced. Name it after the installation location.
Camera Source	Connection method and address.
Orientation	Rotation by 90, 180, or 270 degrees, horizontal/vertical flips, and combinations. Use it when the camera is mounted at an angle.
Region of Interest (ROI)	Named areas defined on the frame, drawn as rectangles or polygons.

A region of interest crops the frame given to the AI before analysis. Analysis becomes faster and accuracy improves significantly for small subjects. A detection zone filters the results, so that only detections inside it are counted.

Use a region of interest to feed one part of a machine to a classifier; use a detection zone to count only what passes through a doorway.
