Axis’ Zipstream compression technology now automatically adapts to PTZ camera movements

March 2016 by Emmanuelle Lamandé

Axis Communications introduced a new release of Axis’ Zipstream compression technology that now automatically adapts to PTZ camera movements.

Axis’ Zipstream technology analyzes and optimizes 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 better storage savings.

PTZ camera movements can cause bandwidth spikes resulting in frames being skipped, both in live operator viewing as well as in recordings. Axis’ Zipstream compression technology is now able to adapt to these camera movements. Bandwidth spikes can be avoided thanks to a new dynamic rate controller that is automatically enabled when the camera is being panned, tilted or zoomed.
