In recent years, security measures at critical infrastructures sites, such as power plants, power distribution networks, water reservoirs, data centers and telecommunication links have been studied in detail to prevent accidents and terror attacks and ensure the safety of workers. For example, an accident at a power plant or in other parts of the power distribution network will potentially have a serious impact, such as loss of life, or that large parts of a community will be without electricity. This will lead to vulnerability in the society’s daily operation and in emergency services. Being a critical part of the society’s security, wealth and welfare, this kind of infrastructure is considered a valued target for terror strikes.
Critical infrastructure consists of different types of key facilities such as power plants generating energy or data centers handling data, as well as important distribution parts of the infrastructure such as power substations, transformers, high voltage transmission masts, power lines, pipes, cables and telecommunications links. Additionally, there are control and operational stations monitoring a robust and secure supply of the resources. This network of units and sites (from now on referred to as critical infrastructure) in need of security measures are geographically spread, often on remote locations with otherwise poorly built infrastructure. This complicates security measures such as fire prevention, perimeter security against intruders and terrorist attacks, as well as providing safety for children living nearby, workers doing maintenance etc. Response to attacks may have to be remotely controlled or automated, leading to high demands for quality adapted to different environments and secure operations.
Detec AS Recommends Solutions That Optimize Cost of Response to Lowest False-Alarm Rate
A good contribution to all these challenges will be a video management system that can handle geographically spread sites that are connected to one or more security centers. Detec Next VMS, possible with Detec Next Enterprise, can do just that.
First, you will need a good overview over sites and where they are situated. With Detec Next VMS you can create a map of all sites in your organization and a free number of sub-maps. Icons of cameras or sensors will start to blink whenever there is an alarm of certain priority, so you can easily locate the alarm source.
Furthermore, different alarms can be given different priority so you can easily focus on the alarms that matters the most.
Detec Next VMS has since the start been developed to be a tool for operators to handle and respond to alarms. The Detec Next VMS has features such as Alarm mode for alarm handling and response, acknowledgement routines, fields for user-defined alarm instructions, rule engine for automatic actions etc.
Detec Next VMS has two types of camera licenses for advanced video analysis that will keep the false alarm rate low;
With these types of licenses, you are able to create detection criteria to capture the following events:
Object moving within an area
Object trespassing an area
Object moves abnormally slow/fast
Object appears in an area
The software should be able to be set up with different and individually customized client or central management solutions for different kinds of users, e.g. one client for monitoring technical alarms and another for receiving alarms on perimeter violations.
Listed below are some of the recommended solutions and products for this market Vertical.
Detec Next Station Inspector
On each location you will achieve three things with one single Detec Next Station Inspector system;
You will be able to measure temperatures at the site, giving warnings on critical temperature changes on vital parts of the power station,
You will be able to secure the areas perimeter against intruders,
And you will be able to give an alarm on early indications of a potential fire by high temperatures even before the fire itself starts, giving security guards and firemen the possibility to react very rapidly and minimize the extent of damage.
The advantages are that:
The system can be scaled according to needs with the number of thermal cameras, PTZ cameras and conventional IP cameras that are necessary
Several local systems on different sites can be connected to a joint security centre
The system gives temperature observation, perimeter security and fire notification in one singular system
Very early warning through images giving more information than other alarm types – assessment on necessity of turn-out is more substantiated
This solution make use of Detec Radiometric Thermal cameras. Such cameras will elevate the security level with less unwanted alarms compared to regular thermal cameras and not least conventional optical cameras. For critical infrastructure, receiving the alarm and act proactively is usually more important than recognizing a person and keeping it for evidence.
With these cameras we are in full control of the camera AGC avoiding the camera to be blinded by sudden large hot objects. You can also set up a fire detection alarm applying a Detec Next RAD license. This may be wanted inside a compound containing flammable goods or nearby petrol pumps for trucks. The same camera can be set up with both PRO and RAD license if practical.
Hybrid Dual Thermal and Optical IP Cameras
With hybrid thermal and optical IP cameras you can combine the best of two technologies for video analysis with fused images from both the thermal and the optical module - videofusion. For high-security intrusion detection requiring a minimum of false alarms this technology is the recommended way to go. Compared to conventional thermal cameras there are some low-cost alternatives that are ideal for advanced video analysis such as Dahua TPC-BF2120-T. This model also support temperature measurement (-T = radiometric).
(For the most accurate temperature analysis we still recommend the Detec Radiometric Thermal cameras compared to TPC-BF2120-T.)
Detec Next VMS and Optex Detectors
Detec Next VMS with advanced video analysis and Optex Detectors have technologies complementing each other. Integration of IP-based detectors on the Detec Next platform may give remote locations more reliable detection and a lower false alarm rate.
