Case study

Dahua IP video surveillance solution upgrades Hangzhou’s Safe City project
The whole system runs Dahua comprehensive central management software DSS
Dahua cameras secure over 70 percent of whole Hangzhou traffic system

Hangzhou, the capital city of Zhejiang province, China, also known as heaven on Earth in an old Chinese saying, is get so used to the praises and appreciation received throughout modern and ancient times, in China as well as elsewhere around the world. Its divinely picturesque scenery, over thousand-year history, beautiful legends, and strong economy, have bestowed the city with a name as dream city. Dahua Technology, a leading video surveillance company, which is nourished on this dream land, has the honor to take care of it.

Securing over 70% of whole Hangzhou traffic system

Hangzhou is consisted of eight administrative prefectures and two sub-urban districts, covering more than 16,596-square-km with a population of 884.4 million. Hangzhou is one of the first Safe City projects in China, building a complete video surveillance system for public and transportation security. The city’s Safe City project has been upgraded by Dahua’s latest video surveillance solution since its first installation in 2004. After this upgrade, Dahua’s cameras are securing over 70 percent of whole Hangzhou traffic system. Take Xiaoshan district for an example, Xiaoshan Safe City started in 2009 and is currently at its third construction phase. The challenge for this project is that the whole video system has to be connected and the video data has to be transmitted from local police stations, municipal management center to provincial management center.

There are 32 local police stations in Xiaoshan equipped with Dahua IP surveillance system, collecting videos from over 3,000 cameras installed at intersections, tunnel / metro entrances, school gates and other public locations where with high intensity. The applied cameras include speed domes and megapixel network cameras, their high performance and 7/24 non-stop working stability ensures clear and crisp image delivery at every second.

Comprehensive central management

In order to process and manage massive data volume, local police stations use 60 units of Dahua network video recorders, which are equipped with a quad-core processing chip and up to RAID5, ensuring smooth operation, data safety and system stability. The whole system runs Dahua comprehensive central management software DSS.

As there is no isolated city island in this world and data only matters when it plays its role, the big data received and processed at the base tier are transmitted via optical fiber and cascaded to the municipal platform and provincial center. Meanwhile, some customised functions are integrated to CMS to make it more timely responsive. And the 5 units of Dahua 3 x 4 DLP video-walls are served to provide a bigger view of the ongoing surveillance areas so it can better optimise the manpower and police operations, enabling a more efficient system and traffic polices are capable to make instant reaction when incidents happen.

A local installation man mentioned that Hangzhou is where we live and we have a life here, it feels special and honored to protect it by my own hands, kinda like a sense of duty. “Exactly,” seconded Tommy Yang, Domestic Project Director at Dahua Technology, “and actually, not only in Hangzhou, but also in many other cities in China, we have successfully delivered the sense of security to the citizens. And we are proud to say that these projects prove that Dahua team has all necessary capabilities from the planning, to installation. And our products also prove the high quality to ensure whole system’s stability.”
