New: Axis Zipstream compression technology

We heard about Axis’ new Zipstream compression technology at a recent Axis partner event and today Axis has made the formal public announcement that this potentially interesting technology is being introduced into its product range, starting with the existing Axis Q1615 and Q1635 models and the Q35 series. A firmware upgrade on these models will be required to start making use of Zipstream.

So what’s Zipstream?

Axis says its new Zipstream technology analyses the video in real-time and optimises the stream continuously, intelligently separating areas of a scene that are of interest from the areas that are of little interest. The quality of the interested areas will be maintained whilst the quality of the less relevant areas will be reduced. Think for example about a car driving on a road, the detail of the car will be of interest whilst the detail of the road won’t be. This process of separation and assigning different levels of quality to areas within a scene will reduce file size, which in turn will reduce bandwidth and storage use.

Axis claims its new Zipstream technology can save an average 50% on bandwidth and storage use. This would be fantastic and a big leap forward in what is one of the key challenges in any large IP video system.

Zipstream is fully compatible with the H.264 compression standard so, in theory, it should work with existing (third party) video management and recording platforms. Axis has not (yet) said anything about Zipstream’s impact on CPU usage, so that’s the first thing we will be looking at.

Zipstream could be a potential game changer. We will put it to the test soon and share our findings with you here. Stay tuned.
