Intelligent Video Surveillance Systems

Intelligent video surveillance system based on image analysis and continuous monitoring of the system performance improve dramatically efficiency of the system management performed by the operator.
The unquestionable advantages of systems based on image analysis and continuous monitoring of the system performance are:

- The duties of several operators taken over by one person
- Elimination of human errors caused mainly by loss of concentration due to monotony of the surveillance job
- Limitation of the number of actions performed by the operator (the rest is replaced by an automated system)
- Self-monitoring of the system and detection of any abnormality
- Possibility of informing about events other users of the system, not being on the spot

Image analysis is an improvement of the video surveillance system that makes the job of the operator much easier. It practically eliminates the most boring part of operating typical system, i.e. continuous observation. Built-in intelligent functions practically eliminate the risk of an oversight of critical events, which is very important for the safety of the monitored place.

The use of such functionality in large systems (with many cameras) allows to reduce the number of operators. Small systems can be fully automated (work without operator). There is also possibility of combined operation, e.g. with operator during days and automatic at nights.
Depending on the structure and components of the installation, the image analysis can be performed in different parts of the system:

- In IP cameras or video servers (with built-in firmware)
- In DVRs (in analog systems)
- As functionality of the managing software (of IP cameras and video servers)

The module of image analysis and system monitoring being a part of the CCTV software NUUO can react to the following events:

- Loss of video
- Motion detection
- Appearance of a new object
- Disappearance of an object
- Loss of focus
- Camera crash

It is also capable of:

- Counting objects
- Monitoring the computer system
- Monitoring states of alarm inputs

Any event can trigger the following action:

- OSD information
- Audio transmission/alarm sound
- Activation of any PTZ camera (preset, route)
- Notification to the headquarters
- Activation of alarm output
- Sending an SMS
- Sending an e-mail
- Phoning a specified telephone number

Each action can be performed for a specified period of time. Find more at: http://www.dipolnet.com/bib603.htm
