A week ago, new iPhones were released along with iOS 11 – a notable event. This release among everything else has brought one more important thing to developers: the Safari browser received long-awaited support for WebRTC.

Think for a minute: millions of iPhones and iPads all over the world suddenly learned to play real-time audio and video in a browser. iOS and Mac users can now enjoy full-functional in-browser video chats, live broadcasts with low (less than a second) real-time latency, calls and conferences and more. The road was long, and now we are here.

WebRTC can work Peer-to-Peer and Peer-to-Server, where the peer is usually a browser or a mobile application. In this article we describe how WebRTC works in the Server-to-Server mode, what this mode is for and how it works.

We all know how to embed a usual player for video (VOD – video on demand) to the page. Typically, this is an HLS player that loads the content piece by piece via HTTP and plays those fragments using the native HLS engine. The native HLS player is peculiar for mobile browsers in iOS and Android platforms. On desktop browsers, HLS players work via Media Source Extensions or using Flash Player.

In this article we demonstrate 7 technologically different ways to display a video stream from an IP camera with RTSP support on a web page in a browser.

As a rule, browsers do not support RTSP, so the video stream is converted for a browser using an intermediate server.

Reportedly, today there are hundreds of millions of installed video surveillance IP cameras. Surely, not all of them require low latency video playback. Video surveillance is typically static – the stream records to the storage and is analyzed to detect motion. There are plenty of software and hardware video surveillance solutions that do their job pretty well.

In this article we will introduce a slightly different usage of an IP camera, namely – online broadcasting in applications where low latency communication is required.

First of all, let’s deal with common misunderstanding of terminology when it comes to webcams and IP cameras.
