The latest edition of Axis’ Zipstream product now offers more storage and bandwidth savings in video surveillance applications, the network video product company says, without it’s claimed compromising on important image details. It works with the H.264 video compression standard.
Axis Communications‘ Zipstream video compression now dynamically adjusts the frame rate, adapting to any changes in the scene. The new dynamic frame rate feature offers bandwidth and storage savings, the company says.
Johan Paulsson, Chief Technology Officer, Axis Communications, says: “Ensuring that important image details are captured at all times is what really counts for our customers. Being able to reduce the bitrate to almost zero when there is no activity means you get everything you need with less of what you don’t. “We are working very closely with our partners and customers listening to ideas and suggestions for improvements to our Zipstream technology. One area where we have seen particularly strong demand for even further reduction of bandwidth and storage consumption is that of continuous recording of scenes with changing activity levels. That’s what we have achieved with the latest enhancement of Zipstream.”
Less storage is needed and existing storage can be used more effectively, the product firm says. Zipstream allows customers to make use of a camera’s full resolution and image processing such as Wide Dynamic Range (WDR) or Axis’ Lightfinder, while at the same time reducing bandwidth and storage requirements. For edge storage applications where video surveillance footage is stored on SD memory cards inside the cameras, the increased retention time is an advantage, the firm says. For cloud storage, the reduction in bandwidth consumption allows for more reliable uploads and reduces broadband connection costs, the company adds.
Forensic details like faces, tattoos or license plates are isolated and preserved by Zipstream, while irrelevant areas such as white walls, lawns and vegetation are sacrificed by smoothing, to achieve those bandwidth and storage savings. The latest Zipstream adds the concept of dynamic FPS (frames per second) to optimize the video stream’s bit rate as an addition to the concepts of dynamic ROI (region of interest) and dynamic GOP (Group of Pictures) being used in existing Zipstream. Users have control over the settings and can customize the product. Zipstream with dynamic frame rate is planned to be available in July 2016.
