Therefore, finding an efficient solution to control and manage these challenges is an important factor in the smooth running of a city. In view of this trend, Dahua's advanced safe city solution enables police, transportation authorities and other departments to deal with safety threats using less manpower but delivering a faster response. The end-to-end solution provides reliable cameras, an integrated platform and intelligent technologies to ensure cities are well guarded and efficiently run.

The solution performs reliable identification via face recognition technology. Armed with the cutting-edge face recognition algorithm from the latest LFW (Labeled Faces in the Wild) results, Dahua face recognition can effectively identify suspects in key and central areas of a city such as, transportation hubs, high-risk borders and restricted infrastructure sectors, instantly. As a matter of fact, more than 100 sets of face recognition cameras have already been deployed to cover the most crucial transportation hubs of Hangzhou during the G20 Summit.

As an integrated platform tasked with unified command and centralised data storage, this provides rapid emergency response and cross-system or cross-department information sharing. Through cross-department collaboration, the integrated platform ensures real-time incident response and better despatch of police resources. In addition, mobile enforcement and emergency preparedness, allow this solution to be more efficient when an emergency happens.

Video synopsis is a typical intelligent analytic tool that allows for a faster and more accurate crime investigation. It provides a short summary including all moving objects from a long video and supports queries on moving objects according to different characteristics like size, colour, direction and speed. Through this big data analytic tool, users are able to identify suspects from massive raw video data in a very short time.

Due to complex working environments, the video quality of devices may deteriorate after long term service. Maintenance work to upkeep video quality and storage quality will potentially become a big problem in the future. With the help of smart diagnose, the detection of malfunctioning equipment can be performed by an automatic maintenance platform. It helps to reduce OPEX and service interruptions significantly. Using advanced technology (4K high resolution cameras, thermal sensing, license plate recognition, face recognition, behaviour detection etc.), the Dahua solution provides good quality video images and smart detection in any weather conditions.

According to the company, after being widely used by many cities, the Dahua safe city solution has been proven to be both efficient and effective in protecting the safety within a city. In addition, because of its innovation and customised system architecture, this is a flexibly designed system, which is ready to be upgraded with technology changes and expanded with city infrastructure growth.
