Dahua Technology Ltd

Dahua Technology, a manufacturer and supplier of video surveillance products headquartered in Hangzhou, China, launched an efficient and reliable safe city solution.

Recently, rapid economic and city development create big challenges to urban centers. The challenges range from crime, terrorist threats, traffic management to natural disasters. Insufficient manpower and system capacity to protect the city from these challenges is a big issue. Therefore, finding an efficient solution to control and manage these challenges are important to a smooth-running city.

Dahua safe city solution

Dahua has created an advanced safe city solution to enable police, transportation authority and other departments to deal with safety threats using less police force but delivering faster response. The end-to-end solution provides reliable cameras, integrated platform and intelligent technologies to ensure cities are well guarded and efficiently run.

Dahua safe city solution was designed with four essential aspects.

Reliable prevention via face recognition technology: Armed with the No.1 face recognition algorithm in the latest LFW (Labeled Faces in the Wild) result, Dahua face recognition can effectively identify suspects in key areas of city such as downtown center, transportation hub, high-risk border and restricted infrastructure instantly. As a matter of fact, more than 100 sets of face recognition cameras have already been deployed to cover most crucial transportation hubs of Hangzhou during G20 Summit.

Real-time response via integrated platform: Integrated platform is tasked with unified command and centralised data storage to provide 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 police resources dispatching. In addition, mobile enforcement and emergency preparedness, allow this solution to be more efficient when an emergency happens.

Because of its innovation and
customised system architecture,
this solution is flexible to
upgrade with technology change
and expand with city
infrastructure growth

Effective investigation via powerful video synopsis: Video synopsis is a typical intelligent analytic tool that allows a faster and more accurate crime investigation. It provides a short summary including all moving objects of a long video and supports query moving object according to different characteristics like size, color, 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.

Easier system maintenance via automatic maintenance platform: Due to complex working environments, video quality of devices may deteriorate after long time running. Maintenance work to upkeep video quality and storage quality will become a big problem. With the help of smart diagnose, the detection of malfunctioning equipment can be performed by automatic maintenance platform. It helps to reduce OPEX and service interruptions significantly.

Using advanced technology (4K high resolution camera, thermal sensing, licence plate recognition, face recognition, behavior detection etc.), Dahua solution provides good quality video image and smart detection in any weather conditions. After being widely used by many cities, Dahua safe city solution has been proven efficiently and effectively in protecting city safety. In addition, because of its innovation and customised system architecture, this solution is flexible to upgrade with technology change and expand with city infrastructure growth.
