Darwin becomes home to first multicast mesh network

Part of $8 million NT Police security project

Darwin has become home to the first multicast mesh network in Australia after the installation of an $8 million 109 camera CCTV self-healing wireless network.

The project, set up to manage six square kilometres of Darwin's CBD, began after the NT Police, Fire and Emergency Services Department awarded the contract to Darwin-based security company, Security and Technology Services (STS).

Managing 109 closed circuit TV cameras initially proved troublesome for the NT Police, which often experienced power outages resulting from lightning strikes as well as the transmission of high definition video streams from cameras to three police stations and a fourth remote storage facility.

Adelaide based network company MIMP was chosen by STS to deliver a highly redundant, high performance 128-bit data encrypted wireless network to integrate Darwin’s central camera system.

STS project manager, Greg Ireland, said the network has helped to alleviate a number of issues in the Top End since it was deployed in December 2009.

“It has helped to solve problems that range from recovering stolen property, dealing with assaults and vandalism to identifying multiple persons on different occasions with concealed weapons, which enabled us to direct police to intercept these persons before incidents occurred,” he said.

NT Police CCTV project administrator, Shane Moten, said the network has actively reduced the number of incidents on Darwin’s streets.

“Since the system has been live, we have generated hundreds of additional incidents that we might otherwise have missed,” he said. “As the video operators become more experienced with identifying developing problems, they are able to proactively look for certain things at hotspots for anti-social behaviour and alert police to intervene before a situation becomes bigger.”

The deployment comes as rain and bad weather delayed the commencement of fibre installation between Darwin and Tennant Creek in the Northern Territory earlier this year.
