Video Surveillance Signs

Tvrdosin in Slovakia - the sign of a new trend in video surveillance

In the evening, a woman returns home along a sidewalk in the area of housing. It is followed by two young men with hoods pulled over their heads. They look around, approach the woman and snatch the purse, then join three others, also identified as criminals ... The authors have taken several days after the execution of a video surveillance system in the new Tvrdosin.

Tvrdosin is a city of more than 10,000 inhabitants, situated 12 km from the Polish border (on the Chyzne - Road Ruzomberk). The region abounds in tourist attractions - Meander Park Thermal in Oravice (point of thermal water), Orava reservoir (artificial lake), and ski areas. The city authorities decided to build a video surveillance system to prevent vandalism and other offenses. The system should be profitable, also in the long term (low cost operations control center).
traditional monitoring based PTZ cameras can be effective if used continuously by trained personnel. In the case of the small city costs would be unacceptable. Dipol Slovakia proposed to build a system based on fixed cameras megapixels. This indicates a new era in monitoring the video - using a combination of megapixel cameras with wide-angle lens instead of PTZ devices.
The system uses eight 2.0 Megapixel IP cameras ULTICAM DS-852MF-E. Three of these cameras have been installed on the walls of the town hall, the rest are deployed in the field of housing, called Medvedzie. This district is 680 meters from the monitoring center. The video is transmitted wirelessly to an access point with integrated antenna - ULTIAIR.
Each of the five parts of the video is sent to a data rate of 4 Mbps, which is sufficient for high quality images (1600 x 1200@12.5 fps). The monitoring center is located in City Hall. The system is managed (monitoring and recording) by software ULTISYSTEM. high-resolution images in both live and read from the archives, can be enlarged several times to identify persons who do not respect the law.

solution put forward the idea of a CCTV system built Tvrdosin and based on the use of fixed cameras megapixels allows the use of modern, intelligent software image analysis, thereby reducing personnel costs related to the operation of the monitoring center. In the future, this type of software will replace people in many surveillance operations. Modern software allows the automatic execution features such as:

• detection of new objects,
• tracking moving objects,
• face recognition,
• recognition of license plates,
• Detection of long stay of a person or an object,
• fire detection,
• counting people or objects,
• analysis of road traffic
• behavior analysis (eg wrestling)
