Arecont Vision camera captures images of speeding vehicles in Buenos Aires, Argentina
Arecont Vision camera captures images of speeding vehicles in Buenos Aires, Argentina

Customer Buenos Aires is the capital and largest city of Argentina and the second-largest metropolitan area in South America. The city of Buenos Aires is an autonomous district, and the separate province of Buenos Aires is the largest and most populous province in Argentina. Challenge The local governments in Argentina needed a portable mobile solution to monitor and document speed limit violations. Megapixel solution In a unique integrated solution, Arecont Vision 5-megapixel cameras are used in conjunction with a radar speed gun. The camera's small size and excellent performance provided the perfect imaging solution for this specialised law enforcement application. The system consists of a radar speed gun, a central processing unit (CPU) module, an Arecont Vision AV5115 5-megapixel camera and a laptop computer for programming and monitoring. The CPU controls and administers all functions of the system. The Arecont Vision camera connects to the CPU through an Ethernet connection, and the radar pistol communicates with the CPU via an RS-232 port. When measuring a vehicle’s speed, the CPU analyses whether the speed is in excess of the speed limit. If it is, the Arecont Vision camera takes a high-resolution digital image of the vehicle for license plate identification and fine processing. The information is then correlated to Argentina’s vehicle registration database and the speed, operator's name, speed limit and location are superimposed on the picture and saved in memory on an SD card housed in the unit. A single SD card can store more than 1,000 files. Local monitoring is performed using a laptop computer, which is connected using a Wi-Fi network. The system also communicates via Wi-Fi to a desktop computer for remote monitoring. The AV5115 camera is part of Arecont Vision's MegaVideo® Compact series of IP cameras. It features H.264/MJPEG dual encoding and up to 32-times the resolution of a VGA camera. Forty of the radar/video speed gun units were built, and the first units have been working uninterrupted since 2009. The handheld radar speed gun system was designed and installed by Dyna Group, Buenos Aires, a customer-oriented company providing high-quality technical and environmental engineering services to its clients, according to Hector H. Zino, manager. Dyna Group's goal is to exceed every client's expectations with outstanding customer service, increased flexibility and greater value, thus optimising system functionality and improving operation efficiency. Dyna Group specified the Arecont Vision camera for the radar speed gun application in Buenos Aires. Megapixel benefits The high resolution of the Arecont Vision camera provides clear images for identification and the ability to read license plates. Megapixel-quality images include greater detail at an affordable price. Value drives the market, and less-expensive systems with higher resolution and better system performance provide the best value. During the design phase, several solutions were tried, but the Arecont Vision camera was chosen as the preferred solution because of performance, small size and easy operation. The system has been well received because of the high-resolution of the images and the small size of the complete device. Better images ensure more revenue from speeding fines, which yields return on investment (ROI) for the new system. The radar/video guns have more than paid for themselves based on increased safety and collection of speeding fines. In one block in Buenos Aires, for example, 98 vehicles in one hour were each fined up to $480 for speeding violations. In another example, there were approximately 200 tickets issued in a single four-hour shift. Residents can request police to provide speed controls in their neighbourhoods based on concerns about the safety of pedestrians. “The solution has worked well, and Arecont Vision has been responsive to the customer's needs,” says Mr. Zino of Dyna Group. “The Arecont Vision megapixel camera provides a very compact and lightweight product at a reasonable price.”

Bosch’s 120 FLEXIDOME IP cameras monitor Dallastown Area School District
Bosch’s 120 FLEXIDOME IP cameras monitor Dallastown Area School District

Bosch VIP XD Decoders transform the digital signal to analogue for viewing on monitors End user: Dallastown Area School District Dallastown Area School District is located in York County, 34 miles south of Harrisburg, in the south central part of the Commonwealth of Pennsylvania. The district serves nearly 6,000 students in five kindergarten through fifth grade elementary schools, a sixth to eighth grade middle school, and a grade nine through twelve high school. The district employs 417 instructional staff, 277 support staff and 30 administrators. Business objective: The school district's IT department sought a flexible IP video surveillance system that would allow administrative staff and the school's resource officer to easily search and playback recorded video to determine the events surrounding incidents at the schools. Secretaries also needed to view video of the entranceways from their desks, in order to see a person requesting access to the school before unlocking the doors. Solution: Nearly 120 FLEXIDOME IP cameras monitor the hallways and cafeterias in the district's high school and middle school. Day/Night cameras provide an extended dynamic range and mechanically switching IR filter to capture video in areas that have low light or that are near windows with excessive light. For recording video, the cameras stream signals across the district's separate security IP network for storage on five RAID arrays For recording video, the cameras stream signals across the district's separate security IP network for storage on five RAID arrays. Video Recording Manager (VRM) creates a virtual pool of storage using all of the RAID arrays, divides the total capacity into one gigabyte blocks and allocates storage for video recording to each of the IP cameras as needed. With cameras that stream directly to RAID arrays, the district avoids using NVRs, which would have required extra time and funds to support. The district's streamlined system design and use of VRM software made installation easier. For example, recording settings were programmed in less than a day, compared to the five days needed for an NVR-based system. The system design is extremely flexible, allowing the IT department to adjust frame rates of cameras in important locations without stopping the system from recording, reallocating storage disk space or reformatting the storage. The district uses video management software to search and playback video. Bosch VIP XD Decoders also transform the digital signal to analogue for viewing on monitors. Result: The school district reports that the system helps administrators more quickly identify which students were involved in incidents that happen in the schools. The students are more likely to be truthful about the role they played, when they see themselves on recorded video. In addition to the cameras already installed, the district's IT department plans to install AutoDome IP cameras around the exterior of the school buildings and in and around the five elementary schools in the district to help protect the younger students from external threats.
