Hangzhou, the capital city of Zhejiang province, China, is also known as heaven on Earth according to an old Chinese saying. Hangzhou has eight administrative prefectures and two suburban districts, covering 16,596-square-km with a population of 884.4 million. Hangzhou is one of the first Safe City projects in China, using video surveillance for public and transport security. The city’s Safe City project has been upgraded by Dahua Technology’s latest video products since its first installation in 2004. 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 at its third construction phase. The whole video system has to be connected and the video data has to be transmitted from local police stations, and municipal management centre to provincial management centre.
Some 32 local police stations in Xiaoshan have the Dahua IP system, collecting videos from over 3000 cameras installed at intersections, tunnel and metro entrances, school gates and other public locations. The cameras include speed domes and megapixel network cameras.
To process and manage such data volumes, local police stations use 60 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 central management software DSS.
Data received and processed at the base tier is sent via optical fibre and cascaded to the municipal platform and provincial centre. Meanwhile, some functions are integrated to CMS for more timely response. And five of Dahua’s three by four DLP video-walls provide a bigger view of the ongoing surveillance areas so it can better use police manpower, so traffic police can react faster to incidents.
A local installation man mentioned that Hangzhou is where we live and we have a life here, it feels special and honoured to protect it by my own hands, like a sense of duty. “Exactly,” said 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.” Visit http://www.dahuasecurity.com/.
