Axis Communications recently announced the launching of Zipstream, the video compression technology, which will reduce storage and bandwidth requirements by up to 50 percent or even more in many video surveillance applications.
In a press release, Axis claimed that its Zipstream technology works seamlessly with the well-known H.264 compression standard. Zipstream can also be used with all of the recently released Axis cameras and other video management software applications without making any extra investment. Axis’ Zipstream technology is meant to be significantly more efficient than other H.264 implementations.
According to Johan Paulsson, the CTO of Axis Communications, the progress made towards producing higher quality images with high HDTV resolutions and the increased performance in low-light conditions have both placed higher demand on network bandwidth and storage infrastructure.
With the new Zipstream technology, users will be able to decrease their storage and bandwidth needs without losing important image details and quality. For instance, with this new technology, twice the amount of video footage can be stored on SD cards in systems built on the Axis Camera Companion and other video recording applications.
Zipstream technology works by adding a new module into the video compression engine of the network camera. This module ensures that vital details in the video footage receive adequate attention while less important data is compressed further to save space. With this new system of video compression, Zipstream analyzes the video stream in real time and optimizes it.
All the scenes which contain interesting and important details get recorded with a high resolution and image quality while the other portions are filtered out for optimal use of storage space. Therefore, vital forensic details like faces, skin marks, and license plates are carefully separated and preserved while the quality of the less important areas like green vegetation and white walls are sacrificed through smoothing to save storage and network bandwidth.
Existing customers may make use of the Zipstream technology with older Axis camera technologies including Lightfinder and the Wide Dynamic Range (optimized for Forensic Capture). Since this new technology is compatible with H.264, it may also be used with the Axis Camera Companion and other 3rd party network video software.
Through firmware updates, Zipstream technology can be used with existing Axis network cameras such as the Axis Q35 series, and Axis Q1615 and Axis Q1635. The first set of new network cameras that Axis plans to ship with Zipstream installed include fixed network cameras like the Axis P1365/-E, Axis M1124/-E and Axis M1125/-E. It will also be included with fixed dome cameras such as the Axis P3224-LV/LVE and Axis P3225-LV/LVE.
The Axis M1124, outdoor ready M1124-E, Axis M1125 and its outdoor counterpart M1125-E, are relatively low cost network surveillance cameras that have several important features including the new Zipstream technology, day and night functionality, CS mount lens, and wide dynamic range forensic capture.
They also possess enhanced capacity for analytics that makes them suitable for retail stores and other sensitive installations either indoors or outdoors. These two series of network cameras are scheduled to be released for sale in the second quarter of 2015.
The Axis P1365 and outdoor ready P1365-E also have Zipstream technology as well as audio capture and remote back focus. These cameras’ outstanding image quality makes them ideal for banking and city security/surveillance applications. They are also meant to be available in the second quarter of 2015.
