Suburb gets ANPR

Chubb Fire & Security, local system integrators and remote monitoring service’s provider was tasked with securing a residential suburb with a manned control room, as well as offsite monitoring. Using strategically placed cameras, the company was able to monitor vehicles entering and exiting the suburb. However, the challenge was to do more than monitor vehicles.

Regal Distributors SA’s Quintin van den Berg explains that the existing Hikvision 9600 series NVR (Network video recorder) solution along with 1.3 and 3 MP varifocal infrared bullet cameras offered exceptional image quality both during day, and at night time, which made identification of vehicles and pedestrians in the suburb a reality. Similarly, the 9600 series NVR along with IVM-4200 VMS software offered great ease of use in the site’s control centre. However, there was initially no way of notifying the control centre when a blacklisted vehicle entered the area, or to do a search for a specific vehicle via the number plate.

Chubb and Regal addressed the problem, with the goal of improving the quality of service and security using innovative technology. Specifically, they wanted to achieve an accuracy rate of above 90% in capturing vehicle licence plate numbers for notifications, real-time reporting and data mining.

“Our biggest challenges were real-time reporting and notification of vehicles entering the suburb that have been flagged by shared databases, or the control room operators. Even if a vehicle was blacklisted, registration number filtering would be a slow and labour-intensive exercise.

Given the existing technology on the site, the Hikvision entrance management system with the ANPR (automatic number plate recognition) technology was the obvious choice, offering advanced management features such as: Auto comparison, Blacklist filtering, Alarm triggering, Result query, Result export of picture/record, Remote configuration ANPR, Linkage action.

The parties decided to opt for the Hikvison DS-2CD4A86FWD-IZS 2.8 – 12 mm motorised zoom ANPR cameras, again supplied by Regal Distributors. The cameras were put to the test in a proof of concept project, after which it was decided that the existing head-end equipment would be used, by upgrading the firmware and field cameras to the DS-2CD4A86FWD-IZS ANPR cameras and calibrating the system to function at optimum performance.

Regal has been involved in this project with the systems integrator since inception and therefore has a vested interest in ensuring the systems work, as required. Van den Berg says the company is constantly measuring the progress, as the system expands. In addition, with the remote configuration ANPR function, Regal can remotely assist with software and firmware upgrades and monitor the performance of the solution.

The result is a fully functioning ANPR system communicating wirelessly to the control room in a well-known suburb in the northern part of Gauteng.
