Axis launches compression tech for network cameras
Zipstream designed for real-time compression of low-importance image areas
Network video specialist Axis Communications today introduced its proprietary Zipstream technology, designed for reduced bandwidth and storage requirements without the need for new cameras or software.
Zipstream is compatible with the commonly used H.264 compression standard. The technology has been developed specifically for video surveillance applications and "lowers bandwidth and storage requirements by an average 50%", according to Axis.
"Significant progress towards better image quality with higher HDTV resolutions and increased low-light performance has also increased the requirements on the network and storage infrastructure," said Baraa Al Akkad, regional sales manager, Middle East, Axis.
"With Axis' Zipstream technology we enable our customers to drastically reduce bandwidth and storage needs without compromising on important image details. For example, more than twice the video footage can now be stored on SD cards or NAS [units] in small systems built on Axis Camera Companion as well as other edge recording applications... Zipstream technology adds a new module inside the network camera's video compression engine, which ensures that important details in the image get enough attention in the video stream while unnecessary data can be squeezed."
Zipstream is designed to analyse and optimise the network camera's video stream in real time. Scenes containing interesting details are recorded in full image quality and resolution while other areas are filtered out, to optimally use available bandwidth and storage. Important forensic details like faces, tattoos or license plates are isolated and preserved, while irrelevant areas such as white walls, lawns and vegetation are sacrificed by smoothing in order to achieve the better storage savings.
"Customers can use Axis' Zipstream technology alongside other Axis network camera technologies," Axis said.
The company is making Zipstream available on existing network cameras AXIS Q1615, AXIS Q1635 and in the AXIS Q35 Series, via firmware updates. The first new products with Axis' Zipstream installed are planned to be AXIS M1124/-E, AXIS M1125/-E and AXIS P1365/-E fixed network cameras, and AXIS P3224-LV/-LVE and AXIS P3225-LV/-LVE fixed dome network cameras.
