The Keys of Large Scale Surveillance

Video surveillance systems (or CCTV) have evolved significantly in the last several years. General surveillance is one of the basic uses of CCTV. When used for this purpose, the system is perhaps more of a psychological deterrence than actual physical control.

Security Efficiency

Access control, and alarms have much in common, and work with an integrated system to keep intruders out of secure areas, limit access to security-sensitive areas, remotely monitor critical areas to reduce the risk of crime and security incidents.

Properly Located

Properly located surveillance cameras can extend the range of the security staff and provide valuable incident information. The properly location can have a significant deterrent effect on property crime. The use of recorded video images has resulted in countless arrests when shared with LEA or media outlets.

Quality of Image

The most crucial consideration in a video surveillance system is the quality of the image received, and this is mainly dependent on the camera and recording equipment used.

Playback Length

The recording retained in a 10-day library as a minimum. It is not uncommon to maintain recorded images for 30 days. The longer you keep, the more information you will be able to retrieve for investigation in the future.

Define the Scale of Surveillance

The main factors to decide the scale are the quantity of the cameras and the recording days of the surveillance area, Usually, the industry which requires higher security will need to keep the recorded videos/streams longer, so that users/IT managers shall be able to playback those videos once there is any terrible incident occurring.

How Many Days Are Usually Kept in What Industry

Money Exchanger, Banks, and Airports, sometimes it could be longer than 90 days. While keeping the longer recorded videos/streams represents to the requirement of larger storage capacity, Here we use a common codec – H.264, HD resolution – for taking an example, and further explore, if the area size is classified, what kind of industry usually requires how many cameras, and how many days of records should they keep.

Different Scale Different Deployment

QSAN provides the total solution to fulfill each scale mentioned above, and the video streaming could be either written into QSAN storage directly through iSCSI, or via CIFS or FC if there is an NVR server sitting between the cameras and the storage in the environment. Considering the scale and the usage.

XCubeNAS Rackmount series, if it is necessary to keep more days for the recorded videos, it is feasible to add expansion unit dynamically, for capacity expansion purpose. And usually, the performance requirement of this scale is not high.
