Brisbane Markets Ltd., which plays a major role in Australia’s food industry by providing and maintaining a clearinghouse for the produce from more than 7,000 growers, recently decided to upgrade its surveillance technology to megapixel imaging. In order to facilitate loss prevention, access control, traffic, incident investigation and general surveillance, Brisbane Markets makes use of a video recording system that previously consisted of analog technology. This analog system had been in place for about 15 years and the company recently decided that a transition to digital recording would be wise. Megapixel IP network cameras were chosen to replace the outdated analog system.
Before the Queensland floods of 2011, Brisbane Markets had already begun to test a seven-camera system of IP network cameras with a variety of capabilities. The flood actually helped to speed up the transition to megapixel imaging because the whole surveillance system needed to be practically built from scratch. The company found it helpful to have had some previous experience with IP video prior to the flood, as that made the overall transition process easier.
There are currently about 100 cameras placed around the premises, and Brisbane Markets plans to add another 40 cameras from Arecont Vision in the near future. Types of network cameras that are already being used on the site include 1.3-megapixel and 3-megapixel cameras that can capture larger scenes in high detail, thereby enabling forensic investigations. In some places, the company has placed network cameras from Arecont Vision’s MegaVideo® AV3130 series, which is a unique dual-sensor, day/night 3/1.3-megapixel IP camera capable of delivering up to 15 frames per second. This versatile camera is well suited to the changeable lighting conditions over a 24-hour period on the company’s premises. Under low light, the camera switches from color mode to black-and-white mode with a different 1.3-megapixel sensor and the frame rate increases accordingly.
Through its experimentation with digital network cameras, Brisbane Markets has noticed numerous benefits of megapixel imaging, one of the most important being that it can cover a wider area with fewer cameras overall. These cameras also offered improved detection and greater reliability, thereby lowering crime levels in the area.
