  title: Reolink Camera HTTP AI Video API
  description: The Reolink Camera HTTP API provides a RESTful interface for controlling and configuring Reolink IP cameras and NVRs. All commands are sent as HTTP POST requests to the /cgi-bin/api.cgi endpoint with JSON payloads. The API supports authentication via token-based sessions, device information retrieval, network configuration, video and image settings, encoding parameters, recording management, PTZ (pan-tilt-zoom) control, alarm and motion detection configuration, IR and LED light control, AI-powered object detection, and live streaming URL generation. Authentication is performed by first calling the Login command to obtain a session token, which is then passed as a query parameter on subsequent requests.
