Image Capture and Big Data management

Historically, security-related video surveillance has relied upon the capture of video streams to allow reactive post-event analysis. To enhance retention periods, camera counts were kept to a minimum, and strategies to maximise storage included reduced frame rates, limited resolutions or increased compression, and time-based recoding. The latter approach meant stored footage would be encoded after a certain period, reducing quality and frame rate, thus freeing up more space.
