Dahua Smart City Solution

by Benchmark

Modern cities are facing an increased level of risks and threats. The need for a smart integrated system that delivers urban security is increasing, with many councils and authorities increasingly looking to achieve smart control of a wide range of facilities. Dahua claims to offer an option with its Smart City Solution.

What is it?

The administration of city centres has traditionally been somewhat fragmented and reliant upon a variety of different departments and authorities dealing with incidents. However, this is somewhat at odds with an increasing level of system integration and smart communications and data sharing.

Dahua’s Smart City Solution makes use of artificial intelligence (AI) technologies to address security and safety issues of cities, towns and large campus-type applications. The use of deep-learning technologies enables video surveillance systems to perform effective risk detection, allowing a more comprehensive understanding of incidents as they escalate. It also allows the use of data mining so the unified platform delivers more real-time insights from the collected information.

The use of deep-learning technologies advances the capabilities of video analysis and delivers enhanced classification of human and vehicular targets appearing in video footage. It can combine facial recognition with other data such as clothing colour, gender, vehicle colour and size, etc..

How does it work?

The Solution has four stages: prevention, detection, response and investigation.

Prevention allows recognising potentially dangerous persons and situations as early as possible. This is achieved by collecting and analysing data. By using advanced forecasting models it can predict events.

Detection incorporates real-time surveillance using deep-learning technologies in smart video surveillance. Recently the system allowed Hangzhou City to detect nearly 30,000 illegal vehicle-based events during the G20 Summit.

Response enables the collection of all relevant data associated with threats, which can then be shared with all stakeholders. This helps to implement and support a unified command position with inter-departmental information sharing.

Finally, Investigation can quickly analyse all associated data and provide insights to manage and resolve incidents. It also presents elements such as a video synopsis, active area analysis, active target analysis and trajectory analysis.

Does it deliver benefits?

According to Dahua, a recent trial of the Smart City Solution in London indicated that security investment by the police could be reduced by 10 per cent, but that crime prevention in the same period actually increased by 0.5 per cent.
