Virtual Fences for Security
From Security Park:
A story on smart cameras at the Port Macquarie Airport in Australia. The airport is using smart camera technology for intrusion detection and to monitor human activity in areas such as the passenger terminal, runway, and parking areas. One of the main uses is for perimeter security, which traditionally uses fencing systems that can be expensive. According the the security manager, smart cameras are easier on the budget and very effective:
Hall said that the perimeter intrusion detection feature within the QOLiT system was of interest to the airport, as high security fencing was not an option for them. “Leveraging off the perimeter detection feature within the VI Activity Detection system costs less than a tenth of what perimeter fencing would have cost. Plus you don’t have the up-keeping costs of fencing repairs and maintenance.” says Hall.
Using a 3D scaling tool within the VI Activity Detection system, users can easily create and preset invisible ‘trip wires’ and ‘barriers’ in the software. Should any human trespass the invisible barriers, even if the perimeter is a long way off in the distance, the algorithms can discern between the sizes and aspect ratios of objects regardless of how near or far they are from the camera. In this way, unimportant activities such as sudden changes in lighting conditions or movement of small animals can be ignored, regardless of where they are in the image.
It appears that the real power of video analytics is in its ability to keep what does need to be addressed and filter out what doesn’t, alerting only when someone or something seems suspicious. “What Port Macquarie particularly like so much about the QOLiT VI Activity Detection system, is that they are alerted to situations that of importance to them. They are getting about ninety eight percent plus accuracy on event alerting, which is what they wanted.” he said.
