For "The Vologda ice cream" the video surveillance system and DWH is updated

The Russian representative office of QNAP announced in September, 2016 implementation of network drives of TVS-x71 series in the updated system of security video surveillance at the Vologda Ice Cream enterprise. Development and a project startup are executed by the system integrator X-Com.

Key task was upgrade of a video surveillance system in the territory of the enterprise as the former solution with analog connection of black-and-white cameras became insufficient on image quality for needs of a security service. Besides, necessary increase in number of cameras for control of all areas and objects would demand complete replacement of cable passages and nodal points and also application of additional storages and video recorders. So far the works on upgrade are completed approximately for 80%, at the same time a new system and drives of data are already used with a 24/7 permanent load.

Network equipment was selected proceeding from such technical characteristics as capacity, disk capacity, flexibility for upgrade and expansion and also price relation, quality and reliability.

A system includes three servers with the software Trassir for processing of flows of more than 120 IP cameras of brands Hikvision and Beward, set as outside in the territory of the enterprise, and in office, production and warehouse. All video data are placed on two 12-disk storage modules QNAP TVS-1271U-RP which, in turn, are connected to servers by 10-gigabit network interface cards. All drives and servers are fully completed by the tough SATA disks Hitachi Ultrastar with a capacity of 4 TB — only 32 pieces. Connection of cameras with servers is performed via 10 ZyXEL GS1900-24HP and GS-1900-8HP switches.

According to QNAP, network drives interact with servers under the iSCSI protocol that lifts a limit for number of video recorders in a system and gives the chance of expansion or replacement of the server if necessary without loss of accumulated information. Formatted disk capacity of RAIDs allows to save video data approximately for a month of continuous observation (at current settings of a system). It is planned that in the future a system will be expanded with increase in volume of the saved data and speeds of their processing. The selected TVS-1271U-RP model provides a stock on performance of exchange and allows expansion of capacity as using replacement of disks by more capacious, and adding disk a regiment. For elimination of a bottleneck in the form of the gigabit network interface all devices were separately completed with 10-gigabit adapters with a sufficient stock of capacity.
