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.
