|A brief survey of the storage market indicates a (configured) cost of between £0.20 and £0.60 per GB of data. If we can limit the GigaBytes of data actually required in each application we can substantially reduce the cost of a digital solution and still reap the benefits of IP technology.
Reduce frame rate
It is often possible to justify a lower "frames per second" setting than originally planned. When the cost differential is made apparent, many end users may suddenly take a new approach to what they "really" need.
The IP CCTV system industry has worked un-questioningly with a 4CIF or D1 screen resolution as standard for many years. Could your application settle on CIF or 2CIF? Would this reduction seriously affect the end user experience? If not, thousands of pounds in storage costs can be saved in IP systems.
It is possible to compromise the quality of an MPEG4 stream by lowering the overall bit-rate from the encoding device. If your system only needs to recognise the presence of an object but not any detail associated with it, then storage space hence money can again be saved.
Reduce RAID level
If cost is the most important feature of a storage system then it is possible to drop from RAID6 to RAID5 or perhaps even RAID 5 to RAID 0. This reduction in reliability will save at least the cost of one high capacity HDD - usually several hundred pounds..
Use MPEG4 not MJPEG
MPEG4 offers a more efficient trade-off between picture quality and required bandwidth / storage. For many security systems, MPEG4 can directly replace MJPEG with as much as 50% reduction in storage overhead.
Do you need to capture video all the time? In a stock-room you may only want to record when a door opens or a light turns on. People walking the wrong way along a platform or running could be another trigger for video recording. Modern video analytics systems are becoming increasingly intelligent. The additional cost of intelligent systems can be offset by the greatly reduced storage requirements.
