Intelligent systems give greater security and more effective utilisation
There are many different security systems available on the market today, but they are usually designed to be operated by the users themselves and to generate information and data for users to collect themselves.
This means that, when there is an event, the user of a video system has to go through video recordings from all the cameras covering the areas where the event might have been detected and recorded. In installations with over 100 cameras, this involves a lot of searching, which is both time-consuming and monotonous.
With a relatively simple extension of a company’s existing security system, it is possible to get the entire system to react in a more “intelligent” way by automatically warning about abnormal events or providing more precise information about an event.
Intelligent video analysis based on behaviour
Making an existing camera system more “intelligent” does not necessarily mean replacing the whole installation with a new one. It is possible to supplement the existing camera system with a software solution that monitors changes in the video image directly from the video cameras.
Over time, the “intelligent” software learns the behaviour for a particular area, i.e. the repeated pixel changes that take place in the video image recorded by the video camera. The normal behaviour is remembered and, with time, will stop triggering alarms. But if there is a change, i.e. abnormal behaviour, the intelligent system will automatically inform the security personnel. Examples might be:
- A building façade, where the normal picture is no movement up the wall of the building. A ladder is now put up against the wall of the building, and the intelligent system registers this as abnormal behaviour. An alarm is automatically sent to the security personnel, who will then investigate the event further.
- A platform in a railway station where the normal picture over time is that people move to and from the platform area. A disturbance arises between some people and one person is pushed down on to the track. This is registered by the intelligent system as abnormal behaviour, and again an alarm is automatically sent to the relevant staff and system users.
- A terminal area in an airport where the normal picture is of passengers and airport staff walking through. An object with the same shape as a bag or a box is put down and left. The intelligent system registers this as abnormal behaviour and an alarm is sent automatically.
This kind of intelligent solution can provide many examples of how abnormal behaviour results automatically in an alarm being given to security personnel, and the main point here is that the system releases the security staff from constantly having to keep an eye on every camera. The intelligent system itself gives a warning when an abnormal event requires evaluation by the security staff.
Intelligent solutions could be of considerable benefit in many situations, such as:
- Surveillance of traffic on roads as well as railway areas and crossings.
- Comings and goings at important buildings, e.g. public and government buildings.
- At museums to monitor abnormal behaviour around works of art.
- Airports, ferries and harbours.
- The energy sector with surveillance of high-risk areas, e.g. power stations.
- Border crossings, embassies and military areas.
- Banks and other places that handle valuable assets.
- Crime investigation.
Invisible perimeter security
It is also possible to extend an existing security system with discrete or invisible sensors that give increased surveillance of a building’s perimeter.
For example, a company might want to be alerted if unauthorised people cross an outdoor area or come too close to a building.
Discrete solutions that can give an automatic warning might for example be:
- Buried sensor cable that sends an alarm when a person (or a vehicle) crosses an outdoor area. The cable registers the movement and via the software can also be configured in zones so that different alarms are given depending on where in the monitored area the movement is registered.
- Laser scanners can be set up so that they project an invisible laser zone, for example along the wall of a building. If a person enters this zone, an acoustic alarm is sounded and a system alarm is sent to the security control room.
- The “invisible” warning systems have the advantage that they can be used to reduce the surveillance and control workload for security staff in many areas, such as:
- Monitoring of outdoor areas around high-risk buildings.
- Museums and exhibitions.
- Dangerous areas.
