SECURITY OVER IP
Protecting critical infrastructure sites IP Based Security Solutions By Tim Biddulph, IP Product Manager, Professional Security Division, Samsung Techwin Europe Ltd
Introduction Successful attacks on critical infrastructure such as water treatment plants, railway lines or nuclear power stations can have repercussions far beyond the financial cost of repairing. Whether the damage is the result of terrorism or metal thieves, the disruption to people’s lives can be enormous and in some cases life threatening. The good news is that leading
Tim Biddulph discusses recent advances in video surveillance technology and the opportunities for IT and network system integrators.
professional security brands can assist IT and network system integrators in competing for these type of mission critical projects by offering a complete one-stop solution that provides clients with an integrated security solution which takes advantage of the very latest technology built into video surveillance, perimeter protection and access control systems.
Critical Infrastructure Activity on a site can be monitored in real time 24/7 either from an onsite control room or remotely from anywhere in the world via a PC on the network, allowing security personnel and operations managers to respond efficiently to any developing incident or emergency. The majority of critical infrastructure sites will already have a high level
of security which is likely to include security cameras. Recent advances in technology has however facilitated an easy upgrade path from what may be an existing analogue system, to an IP network based solution which provides the opportunity to control and monitor the system from anywhere on the network. Most importantly, mission critical video recording can be stored at any location on the network and retrieved from any PC by an authorised user. A high level of redundancy can therefore be introduced by choosing to simultaneously record and store video at multiple locations. The latest generation of HD megapixel cameras offer Intelligent Video Analytics (IVA) including optical tripwire and enter/exit direction detection, as well as an Appear/Disappear function to detect the movement of objects. IVA also has a scene change tampering function which creates an alert if, for example, paint is sprayed on a camera lens or there is unauthorised movement of a camera away from its usual field of view.
Public safety Local authorities and central government departments as well as commercial organisations throughout the world have long recognised the
key role that access control and video surveillance systems can play in ensuring that the general public can safely go about their lives. Detecting and deterring criminal activity and anti-social behaviour, enforcing traffic regulations and managing crowds are just a few of the ways that an integrated access control and video surveillance system can assist security and safety personnel providing an effective response to any threat or unacceptable behaviour. In the current economic climate
it has to be acknowledged that many organisations are likely to have restrictions placed on their expenditure and yet the need for effective video surveillance systems is just as great, if not greater, than it has ever been. Fortunately, help is on hand in the form of a diverse range of security products which can provide cost effective solutions for virtually any project. A comprehensive choice of cameras and domes are available which include models that are weather and vandal resistant and are able to perform effectively regardless of the environmental conditions.
Multiple Streaming Many of the latest cameras and domes offer multiple streaming, with a choice of MJPEG, MPEG-4 and bandwidth friendly H.264 compression methods, providing the option to simultaneously transmit images to multiple locations at various frame rates up to 25 frames per second, and at different resolutions. This allows different authorised users to monitor live images at one location, whilst recording video evidence at another. At the same time, images can be saved onto an on-board SD memory card and email notifications of any incidents sent to a smartphone. Progressive Scan technology
incorporated into a large number of cameras and domes optimises high quality video capture of moving objects making it possible, for example, to read car number plates without a motion blur effect.
