SUPERMARKET applications have very particular challenges. Not only are there multiple fields of view required; including aisles, PoS locations, entries and exits; there are also the challenges posed by towering shelves that block side views, even from oblique angles.
Depth of field is another key issue in retail aisles. Given the typical length of aisles, more than one camera is typically needed if face recognition of shoplifters is the goal. And if fixed cameras are used, there are inevitable blind spots that in the past have been ‘covered’ using smoked domes that create doubt in the minds of would-be criminals at the expense of higher performance in lower light levels.
DARWIN’S street camera project required Security & Technology Services to integrate 47 existing CCTV cameras deployed at hotspots – mass passenger transport systems as well as bus interchanges – with 62 new IndigoVision PTZ cameras. These cameras are installed at popular congregation points at Casuarina, Palmerston and Darwin.
Due to the prohibitive cost of connecting all the cameras with fibre optic cable, STS needed a highly reliable wireless network to allow NT Police personnel to monitor the 109 cameras, control them remotely and record high-resolution vision of any incidents that are of a quality fit for use in a court for prosecution purposes.
Major challenges of transmitting high definition video streams from the cameras to 3 police stations – plus a fourth remote storage facility – were to avoid network congestion from the large volume of data traffic and to eliminate the risk caused by single points of failure.

IT’S not often we review video surveillance systems that demonstrably make a difference to their communities but this one does. Installed in the town of Wellington in central western NSW in response to business concerns regarding street crime, this modest CCTV solution had a big job to do.
I visited Wellington with Pacific Communications’ NSW state manager Scott Myles and account manager Nicholas Coghlan and talking with the boys as we drove through the rich and rolling farmland between Orange and Wellington, it was clear that at multiple levels this was no ordinary installation. Sure, there were the classic challenges of public surveillance, including getting multiple video signals through a built environment and providing high quality images in low and harsh light. But there were other challenges, too.
Carillon City shopping centre, managed by Western Australian-based property group Hawaiian, is a shopping centre located in Perth, Australia. It’s a large centre with 11,760sq metres of floorspace catering to more than 130 specialty stores in Perth’s CBD. Tenants include 45 fashion stores ranging from national brands to emerging designer boutiques, nearly 20 jewellery stores and more than 25 food retailers.
Carillon City sought to gain a greater understanding of customer traffic in order to share this information with its tenants so they could grasp the impact of their marketing campaigns. The main concern was measuring footfall (people counting), to understand exact number of visitors overall, as well as breakdown of customers per hour, day and more.
IN many ways, the upgraded video surveillance solution at the Sheraton on the Park Hotel is a perfect example of the flexibility and power of IP solutions arguably best expressed not as an end-to-end digital system but as a hybrid. It might sound like sacrilege to talk up the capability of hybrid IP solutions but the fact is that when it comes to balancing cost and functionality, hybrids currently make a lot of sense.
Capable hybrids like this one leverage existing cabling and cameras and save the serious money for building back ends actually capable of supporting HD and megapixel cameras without incorporating bizarre internal contradictions like heavily reduced storage resolutions and throttled frame rates.
SPECIALIST security technology organisation Vision Intelligence has used one of Fujinon’s high quality D-60 surveillance zoom lenses to watch over the M24 midget submarine wreck, the only Japanese midget submarine wreck located in Australian waters, which lies 5km off of Bungan Head in Sydney.
According to the director of Vision Intelligence, Dr Maher Magrabi, Vision Intelligence offers design and consultancy services for custom security and surveillance projects.
“As Fujinon lenses are seen as the benchmark in quality and reliability we always try to design them into our system solutions wherever possible – that’s why the D-60 was included in the M24 midget submarine wreck surveillance project,” he says.
TRANSIT Australia Group is the largest privately owned public transport company in Queensland, Australia. From bus manufacturing through to the delivery of scheduled, school and chartered services, the company delivers transport products and services to the government, the industry and various communities of Queensland.
Sunbus is one of the bus production entities owned by Transit Australia Group, carrying residents of Sunshine Coast, Rockhampton, Townsville, Magnetic Island and Cairns. Additional similar organizations under Transit Australia Group oversee other neighbourhoods, such as Gold Coast and Tweed Shire.
Recently Sunbus embarked on a first and foremost surveillance system establishment throughout the facilities. As this is a depot surveillance project, there are various sections on the premise that need to be covered.
MYER is Australia’s oldest, largest and most prestigious chain of department stores. The company was founded in 1899 by Sidney Myer, and the first store opened in Bendigo. By 1935, Myer employed 5500 people and over the years, through organic growth and acquisition, it became one of the most recognisable names in Australian retailing.
It goes without saying that so venerable a business has a long history of success in security and loss prevention. And when powerful new IP CCTV technologies became available, Myer management was eager to use them to enhance safety and security and to protect the business from shrinkage and fraud. The result was one of the first and largest IP CCTV projects ever seen in this country. It was also the first serious application of megapixel IP surveillance technology.
RETAIL centres are tough. Not only are there large door numbers spread over vast areas and multiple levels, these sites are in large part open to the public and this increases the pressure on internal access control systems, policies and management strategies. Adding to the challenges at Como Centre are the presence of multiple lifts in multiple buildings, as well as multiple tenancies.
Como Centre is a large site, covering an entire city block. The central features include 5 tower buildings with high profile commercial tenants and a multi-level retail mall comprising boutique stores. Multiple buildings comprise a challenge on their own but at Como Centre there were other challenges to consider.
BIG site surveillance applications generate enough interest to enthrall SE&N readers in their own right – especially when the system in question comprises 100 IP cameras - some HD and some megapixel - all supported by a dedicated fibre LAN, a couple of powerful servers and one of the industry’s nicer video management solutions.
But Brisbane Markets Limited’s application appeals on so many levels it’s not easy to know where to start. It’s not just that this is a cutting edge IP surveillance system. Nor is it that it’s a physically huge site, an enormously busy site or a vital piece of the national food chain - particularly for Queensland.
