Tbilisi Metro, operated since December 1966, is a rapid transit metro system and at present consists of 2 lines with 22 stations. Constructed at the depth of 100 metres 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.

From the perspective of surveillance system deployment, the environment of Tbilisi Metro is quite complicated. As the metro is built underground 100 metres deep, it requires advanced deployment that could support strong network connection. Hence, optical fibre 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The original surveillance system that Tbilisi Metro used was gradually outdated and failed to satisfy the need of monitoring a greater number of IP cameras.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.

The new system was upgraded with the deployment of a total of 27 units of the QNAP Viostor NVR VS-8040. 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, fulfilling the demand of Tbilisi Metro for an intensive surveillance solution.

The security administrators were always busy and under pressure. A device with an 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, thereby greatly improving work efficiency.

"This is the second big project where we have adopted QNAP Security products, and the experience and results 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 perfectly fulfills our demands for the sophisticated surveillance environment.”

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.

Whilst additional lines of Tbilisi Metro are under construction, the newer Viostor NVR models VS-8100 Pro+ series and VS-8100U-RP Pro series are being considered for future deployment. Both models, available in 48, 40, 32, or 24-channel, are equipped with more powerful Intel Core i3-2120 processors and deliver better performance on video and audio streaming from multiple channels. While supporting up to 48 monitoring channels, 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, giving even tighter surveillance at Tbilisi Metro’s security.
