Camera Multi-Streaming Usage

Author: IPVM Team, Published on Nov 22, 2017

IP cameras typically support multiple streams, allowing a single camera to transmit multiple streams at different resolutions, frame rates and even codecs.

The most common use case for multi-streaming is for display purposes. For example, a client may display the maximum resolution stream when a single camera is shown by itself but only a lower resolution stream when cameras are displayed in a 3 x 3 or 4 x 4 matrix.

The benefit of this multi-streaming is that it saves significant client-side bandwidth and processing power. At the same time, there would typically be no visible quality loss since monitors generally do not have high enough resolution to display 9 or 16 1080p (or 3MP, 4MP, 4K, etc.) cameras side by side.

But how often do integrators take advantage of multi-stream support? 100+ integrators told us how and why they use multi-streaming.
