Boluo-Shenzhen Expressway is an important part of the fourth vertical expressway that links Shenzhen, Hunan and Renhua in Guangdong province. Connected to Yanpai Expressway, it is a major north-south road for the province and a key express link between Hong Kong/Macau and Hunan/Jiangxi. The entire expressway is designed for six 2-way lanes and a vehicle speed of 100 km/h. 50% of the expressway comprises of large bridges and tunnels.
Mission
Boluo-Shenzhen Expressway is an important part of the fourth vertical expressway that links Shenzhen, Hunan and Renhua in Guangdong province. Connected to Yanpai Expressway, it is a major north-south road for the province and a key express link between Hong Kong/Macau and Hunan/Jiangxi. The entire expressway is designed for six 2-way lanes and a vehicle speed of 100 km/h. 50% of the expressway comprises of large bridges and tunnels. In order to enhance safety management of the expressway, there is a need to ensure uninterrupted 24-hour surveillance of road conditions and create a safe, trustworthy, high-definition smart video security system that includes surveillance of the tollbooth management center and rest areas. This also meets the requirement for superior security technologies for expressway surveillance.
Solution
Axis HD cameras including Axis Q6035-E, P1343 and P3363 are placed at 350 surveillance points along Boluo-Shenzhen Expressway. The entire network comprises of HD cameras along the main expressway, tunnel surveillance cameras, tollbooth surveillance cameras and surveillance cameras at the management centers and rest areas. Real-time transmission of high-definition images is achieved through fiber-optic communication. The surveillance system is designed such that different camera models are selected for each surveillance area based on the required functions: Axis P3363 low-illumination dome camera fitted with the latest sensor chip is used for the office area and tollbooth; Axis P1343 network camera fitted with a special 50mm lens is used inside the tunnel; Axis Q6035-E 1080p 2 megapixel high-speed IP dome camera with 20x optical zoom is used along the main expressway.
Result
This is the first time that a fully digital surveillance system and high-definition IP cameras are used for an entire expressway by Guangdong Provincial Transportation Group. The entire system is transmitted via Internet, phasing out the optical transceiver model of conventional analog surveillance systems and producing huge savings of construction and maintenance costs. It brings HD clarity, high resolutions and huge growth potential that were once far-fetched. The Axis IP cameras directly send digital video images through the IP network (LAN/intranet/internet), allowing users to view high-definition real-time surveillance images with a resolution of up to 1080p on connected computers anytime, anywhere through the client terminal so long as there is sufficient bandwidth. This facilitates visual management and adds variety to the system.
