The challenge for this project is covering multiple monitoring sites from roads, parks, school and public areas alike. These sites have one thing in common, open areas, and the system also requires a monitoring centre to manage hundreds of network cameras and to process and store massive data flows as well as to respond quickly if any incident or unusual events are identified.

Meanwhile, whilst choosing the cameras, several factors were taken into consideration, such as detailed image quality, outdoor environment and variations in the backgrounds to be monitored; selecting the right lens for the network cameras was also a big concern.

It was decided that without a doubt, an IP solution was definitely the answer to all the challenges. Therefore, the whole project was dependent upon three main factors — IP data transmission, video surveillance devices and central management software (CMS).

The final solution consists of nearly 200 units of Dahua megapixel network cameras and speed domes, a pair of high-channel network video recorders as well as 11 units of network keyboards. The monitoring centre is situated in the local police department, from where, hundreds of megapixel cameras are managed and mass data volume is centrally processed and stored. The office uses seven units of Dahua servers equipped with a quad-core processing chip and HDDs of high capacity to run Dahua CMS and NVRs, in order to fully ensure the smooth operation, data safety and system stability. Meanwhile, the bureau has adopted 7 units of 42-inch 1080p LCD video-walls to take control of all on-going images. At the transmission end, optic fibre is featured in the project as physical support for data transmission while the auxiliary devices are wirelessly deployed.

A local municipal official pointed out that the project is designed to combat crimes in an effective and friendly way, which also leads to an optimisation of police operations. “The municipal government has received quite a lot credit from our citizens since the deployment of the project,” the official added.

“Through this project, it demonstrates that Dahua’s HD network solution has lived up to the high standards that city of Moinesti requires,” said Michael Chen, Vice President of Dahua Technology. “With ample city surveillance projects on line in China, we certainly have the capabilities for similar projects in other areas.”

“Our HD network solution includes front-end, back-end as well as TV wall, ensuring that our products and technologies are different from those that other suppliers might offer,” added Chen. “We will continue to offer solution-based systems to our customers not only for city surveillance projects but also other vertical markets, such as retail, hotel and transportation.”
