Axis reduces bandwidth with Zipstream video technology in its PTZ cameras

Compatible with the H.264 standard, This manufacturer's technology reduces by half the need for bandwidth and storage for video surveillance systems.

Now available for PTZ cameras from Axis Communications, This manufacturer's Zipstream video technology allows creating network security projects with limited bandwidth and saving on storage thanks to the lower volume of data required, since it adapts to the movements of PTZs in real time. Therefore, data transfer spikes are smoothed, explains Sergio Fukushima, technical manager of this company.

Despite advances in digital video quality in recent years, many network security projects using cameras with HDTV resolutions, Full HD or 4K have to reduce either the resolution rate or the frame rate precisely due to network limitations. In some cases, new images are recorded over recent recordings due to lack of space in the storage system.

The problem with this, Fukushima points out, is that these measures make it difficult to identify details in the video when an incident occurs, whereas with Zipstream technology there is no visible loss of image quality.

This additional lossless compression is achieved by adding a module to the camera's video compression mechanism, ensuring that important image details are prioritized in the video stream, mientras que los datos innecesarios se eliminan.

In this sense, las grabaciones que contienen datos de interés potencial se registran con la más alta resolución y calidad de imagen y otras áreas se filtran para optimizar el ancho de banda y almacenamiento. “Información de vídeo como caras, tatuajes o placas de vehículos se aíslan y se conservan a expensas de datos irrelevantes, tales como paredes blancas y vegetación”, puntualiza.

La tecnología Zipstream se ajusta automáticamente a los dispositivos, es compatible con el estándar H.264 y está disponible para los modelos Axis P5514 y P5515, así como en las cámaras de las series Q61 y P56, y en Q6000-E.
