What are the connectivity protocols for reading the detections?

I’m experienced with interfacing directly with various camera types, and I’ve seen the NodeRed demo of the reCamera. However, I’m curious about what’s happening behind the scenes. Is the demo using event data in XML format over RTSP, WebSockets, MQTT, or some other protocol?

Also, does reading the camera data require a USB connection or NCM network driver, or is there a more efficient way to access the data?

Ideally, I want to connect the cameras over PoE and read the data streams (only) across a LAN. Any additional information or insights on this setup would be greatly appreciated. Thanks!
