CCTV manufacturer Geutebruck says its new Fading Long Term Memory option slashes the cost of network archiving and allows systems to retain video for long periods using only a fraction of the normal storage capacity.
The FLTM software progressively reduces the frame rate of stored footage over time. It reflects the fact that different kinds of event are discovered, handled and investigated in different timescales; and that residual risks reduce with time. A CCTV system employed to prevent robbery, vandalism and fraud retains a video record for 30 days and can store all its footage at 25 fps for the first three days. It is reduced to 6.5 fps for the next four days, then stores 1 fps for the remaining 23 days.
This cuts the total storage per camera required from 1.3 TB to 290 GB, and slashes archive costs without affecting utility or security.
