Tbilisi Metro Uses QNAP Security's NVR Solution to Safeguard the Underground City

Background
Tbilisi Metro, operated since December 1966, is a rapid transit metro system in Tbilisi, the capital of Georgia. At present, the system consists of 2 lines with 22 stations. Constructed at the depth of 100 meters underground, Tbilisi Metro is one of the deepest subways in the world. Many people in the city depend heavily on Tbilisi Metro for daily traveling because of its convenience.

Challenges
From the perspective of surveillance system deployment, the environment of Tbilisi Metro is quite complicated. As the metro is built underground 100 meters deep, it requires advanced deployment that could support strong network connection. Hence, optical fiber is used for any network appliance in the metro system to fulfill the demands of high-speed intranet connection. On the other hand, being one of the busiest public transportations, Tbilisi Metro is always crowded with people, and the need for an intensive surveillance system deployment is necessary to provide people a safer environment.
The original surveillance system that Tbilisi Metro used was gradually outdated and failed to satisfy the need of monitoring a greater number of IP cameras. As a result, Tbilisi Metro started to look for new surveillance solution that could carry out superior performance of smooth video streaming from a large number of IP cameras.

Solution
Taking system performance and reliability of video/audio streaming as the first priority, Tbilisi Metro chose QNAP^® Security surveillance solution to upgrade its security system infrastructure, with totally 27 units of QNAP^® VioStor NVR VS-8040 deployed. The 8-bay NVR VS-8040, powered by Intel^® Core™ 2 Duo 2.8 GHz CPU and installed with eight 3TB hard drives, offers up to 24TB large storage capacity for long-term recording and presents remarkable performance with maximum 360 Mbps throughput to support simultaneous monitoring and recording from 40 IP cameras. The demand of Tbilisi Metro for an intensive surveillance deployment was well satisfied.
The security administrators were always busy and under pressure. A device with easy-to-manage and simple-to-use interface was the key concern for Tbilisi Metro. Even without much IT expertise, the security administrators could easily learn how to manage the VS-8040 and the installed IP cameras through the handy user interface. The work efficiency was therefore greatly improved.
"This is the second big project we adopt QNAP Security products, and the experience and result are still satisfying and impressive," said the managing engineer of GESCO Group. "The VS-8040 has delivered quality performance of video streaming and stability, which right fulfills our demands for the sophisticated surveillance environment."

Result
QNAP^® VioStor NVR VS-8040 effectively supports Tbilisi Metro's demand for monitoring a large number of IP cameras at each critical corner around the metro stations. Tbilisi Metro now provides people with enhanced protection with the assistance of QNAP^®Security surveillance solution.
While additional line of Tbilisi Metro is under construction, the newer VioStor NVR models VS-8100 Pro+ series and VS-8100U-RP Pro series are considered in future deployment. Both models, available in 48, 40, 32, or 24-channel, are equipped with more powerful Intel^® Core™ i3-2120 processor and deliver better performance on video and audio streaming from multiple channels. While supporting up to 48 channels monitoring, the VS-8100 Pro+ series and VS-8100U-RP Pro series provide an ideal surveillance solution for Tbilisi Metro's need for wider scope of IP camera deployment, fulfilling closer look at Tbilisi Metro's security.
