Dahua guarantees passenger safety on Recife metro

For the deployment of this surveillance system, 1.380 Dahua Technology high-resolution cameras, DH-IPC-HF5231EN-Z-S2 models, DH-IPC-HF5231EN-S2, DH-IPC-HDBW8231E-ZS2 and DH-SD65F230FN-H. All of them are equipped with H.265 compression and video analysis.

Recife's urban train system, in Brazil, transports near 400.000 daily passengers day. To ensure passenger safety he decided to optimize his surveillance system with modern technology and monitoring equipment.

The main challenge to be faced was adapting the technology to the specific conditions of the environment, like lighting, the flow of people and the speed of a subway station without interrupting the shuttle service. Ease of operation, installation and high availability of the system were key requirements for choosing the surveillance solution.

The Brasileira Companhia de Trens Urbanos (CBTU), company in charge of managing this transport system, initiated a recovery plan for stations, Trains, electrical systems and permanent roads last year. For later, start a phase to focus on safety. In the deployment of this surveillance system, 1.380 high-resolution cameras Dahua Technology.

The Dahua Intelligent Surveillance System, with integrated analytical video, Monitors 52 places scattered throughout the 71 km from the railway line of the capital and the metropolitan region.

The project led by Avantia Group, responsible for the installation of the infrastructure, has chosen to combine four models of network cameras: DH-IPC-HF5231EN-Z-S2; DH-IPC-HF5231EN-S2; DH-IPC-HDBW8231E-ZS2; and DH-SD65F230FN-H. All of them are equipped with H.265 compression and video analysis.

These cameras work every day capturing and identifying images. With the amount of data that is analyzed daily, the H.265 video compression pattern, a format twice as efficient as its predecessor (H.264), is essential as it uses only the 50% bandwidth, maintaining quality.

The equipment that uses Dahua's main features (H.265 compression, Analysis, Starlight) has strengthened the safety of the Central and South lines of the Pernambuco metro and has allowed operators to get detailed views of the metro's operations, especially during rush hour or during tourist events, like carnival.

Day and night, in difficult lighting conditions and even at points in low extreme light, Dahua's Starlight cameras deliver crisp, colorful images to the surveillance center to ensure the best performance in very low-light conditions (0,005 Lux).

Technology strengthens user protection in a general way, as it prevents intrusions into vital areas of operation, depredations or other situations that could make it difficult to transport passengers. With video analysis, even if the video surveillance operator is not tracking images from a specific camera, the system automatically identifies and alerts a detected movement in a restricted region, For example.

With the help of Dahua network cameras, passengers coming and going from the Central and Southern lines have the protection of safety equipment in multiple locations throughout the metro operation. The new video surveillance system was designed to operate in centralized management, that differs completely from the previous single management model. Like this, with this change, it was possible to make better use of the security team's human resources in the 37 Stations.

It was thought that Dahua's entire video surveillance system not only guarantees the physical safety of each user, but also avoids a common problem that has a big impact on the quality of service: vandalism. With these cameras it is possible to identify suspects, activate the maintenance service in a more agile way and minimize the impact on the operation.

Video sequences of events occurring within urban train system facilities can be shared with the Military Police, if necessary, you can search the image database and use resources such as zoom to capture details that aid in investigations.

"The cameras are being installed and monitored centrally, in a control room. In the future, we want to achieve a cost reduction for the company, because with the cameras we were able to reduce local surveillance at some metro stations, but the big advantage will be seen in the safety of our passengers. The images help us identify crimes at the stations and send this information to the police", comments Leonardo Villar Beltrcao, SUPERINTENDENT of Recife of CBTU.

"This project is of paramount importance to Spectra. We have been close to Avantia and Dahua Technology throughout the implementation process, providing them with all the necessary support in the delivery of solutions", Reginaldo Mattos explains, director of Spectra Systems, company responsible for supplying the equipment.
