Increasingly, a factor likely due to widespread use of crime everywhere, when it comes to safety we immediately think of the surveillance or at least to all those devices that allow a global control and extended in time.

Video surveillance is a system of continuous monitoring of certain points considered after careful investigation "strategic" to control the entrances and exits to roads, homes, warehouses or stores. These monitoring methods are usually installed after a specific design safety systems that are able to ensure a proper control intrusion.

These safety devices have gradually improved their quality both in terms of efficiency and quality of the images are captured with such schemes. Many cameras are now implementing progressive scan and megapixel resolution that have nothing to envy to the cameras and professional video cameras. These little gems of technology it can give a good if not excellent picture resolution even in particularly difficult situations such as in dark scenes and shadow thus allowing a truly optimal sharpness and clarity. In fact, right now, these devices can enable the identification of people, animals and objects in virtually all occasions thanks to the technology of digital video surveillance systems allowed with the next revision of the images from the surveillance experts specialized in the maintenance and control of these operations.

The applications of this type are applicable in almost any context, are not randomly chosen by many public authorities to monitor income and expenditure in the various municipal offices but also in monitoring income and expenditure in industrial areas, areas at risk from the very point of view of the robberies because of their isolation from residential areas and their structure that allows criminals to disperse in different ways. Not only that, given the recent cases of crime registered in many cities, these devices are irreplaceable witnesses of crimes and killings. It is tangible proof of the many processes that use footage from these cameras as evidence in support of its argument, clear and irrefutable evidence that can not be denied in any way.

Surveillance cameras are therefore the future of security as each camera in addition to being completely independent is classified as "intelligent" or capable of moving and guiding its recovery on the basis of what actually falls within its range action. Thanks to an integrated image analysis software on each camera is no longer needed the continuous presence of an attendant who checks the juggling multiple monitors in an arduous and humanly impossible. Many are also supplements that can be implemented at all levels with the phone for example organizing a telephone warning to a very specific device or directly with the alarm system by closing the plant after finding the images and have them analyzed. A hard blow to the robberies and thefts that can be installed into a private residence.

A technological advance that cannot fail to surprise with its usefulness, and usage patterns.
