30 days to a safe city

Located in north-western Argentina, Cutral-Có is the second largest city in Neuquén Province and a major oil producer in the region. Due to the recent economic downturn and the resulting crime, on top of inefficiencies in the traffic system that often cause painstaking gridlocks, the city needed an efficient, reliable solution that would secure the its nearly 50 000 residents and natural resource infrastructure.

This led former Cutral-Có mayor Prof. Ramón Riosecoto to call for a comprehensive video surveillance system that would monitor traffic, improve city management, streamline responses to neighbourhood emergencies, support the civil defence force, and safeguard urban areas. Without such a system, integral public services would not be able to function properly, thus delaying the city’s modernisation process. In coordination with the Cutral-Có government, Dahua stepped up to the task and formed an action plan that would become one of the country’s most advanced security grids.

At the project’s core, Professional Surveillance System (PSS) software was selected to design and manage deployment of the system’s numerous speed domes and camera components. With support for 256 simultaneous device connections, all 242 of the project’s components could be managed from one system.

In order to handle the massive flows of data from multiple high-resolution cameras, the Dahua DH-NVR6000 series network video recorder was integrated to provide 64 TB of storage out of the box, with another 128 TB added through network storage, bringing its total storage capacity to 192 TB and allowing the system to record and store video in full HD resolution for 45 days. The long archive time offered by this setup is ideal for intense data analysis and various facial and plate identification applications.

Dahua SD6C230S speed domes were chosen to provide coverage around urban areas due to their long-range capabilities.

With 30x optical zoom and 16x digital zoom at a resolution of 2 megapixels, the speed domes are ideal for crime prevention units and automatic number plate recognition (ANPR) at variable distances, performing well on objects at ranges of over 320 metres. These speed domes were installed at the main entrances of integral public sites such as hospitals, schools, police stations, and crossroads.

To accommodate various geographical constraints, a portion of the speed domes were interconnected wirelessly, while others were connected by optical fibre. An uninterruptible power supply (UPS) was used to power each to ensure 24/7 operation.

Three megapixel fixed DH-IPC-HF8301E Ultra-Smart network cameras were placed in areas of high risk. Their progressive scan CMOS sensor, varifocal lens, and motorised auto-iris, coupled with a multitude of smart detection features, including facial detection, enable the cameras to perform during the day or at night, even in the absence of infrared illuminators.

SMART Professional Surveillance System (SMART PSS) software was used to achieve integration with the network of cameras and digital components. This setup allowed the city to host its own Internet-based data centre administration system, which is the first of its kind in Argentina. Optical fibre provided by Internet providers Telefónica and Copelco provided the system with the high-bandwidth capacity required to support intense data traffic, which was managed through the SMART PSS software’s load balancing system.

Vigilancia Online S.A., a Dahua partner company, accomplished smooth installation and integration of the system’s 242 cameras in only 30 business days.
