Introduction

Metropolis Media Service (MMS) is abstraction layer for third-party VMS.

MMS is designed as a scalable service which supports pluggable adaptors. It provides a standard REST API to manage video streams and abstract VMS specific complexity. API endpoints help retrieve RTSP URLs from VMS and supports WebRTC streaming for live and recorded streams hosted at VMS. MMS also supports overlay bounding box feature in WebRTC streaming of recorded streams.
