What is IP - video surveillances?
During an era of worship and an enlightenment of the computer equipment seem that the personal computer (PC) will not bypass any field of activity of the person. There did not pass the personal computer and by security systems. And it is valid, introduction in security systems of this technical tool capable to process and analyze, excludes such emotionally unstable phenomenon as a human factor. The most active gait of the personal computer takes root into systems of security video surveillance. It is a little theory for fans of exact definitions and formulations. Formation of such direction as IP - video surveillance, is obviously possible as a result of the process called by convergence. In this context we will understand merge of two directions as convergence: IT - technologies (IT - information technologies, deal with use of the personal computer and the software for storage, transformation, protection, processing, transfer and obtaining information) and actually systems of video surveillance.
So, knowing convergence, we have an opportunity of creation of conceptually new system which is completely constructed on specialized IP - video equipment. In this case IP - video cameras which already contain the device of a compression and digitization of a signal, and also built-in web - the server allowing to look through the image with any connected in the personal computer network will be necessary for us. Now leaders in the sphere of development of IP - chambers are such firms - producers as Axis Communications, Bosch Security Systems, Panasonic, etc.
in the presence of a large number of chambers needs also to use switchboards and routers.
Food of IP - system can directly be carried out on the local computer network that becomes possible thanks to the PoE technology (Power over Ethernet) - the technology allowing to transmit to the remote device together with data electric energy through standard twisted couple in the Ethernet network. At the same time, both IP - chambers, and ports of network devices have to be equipped on the PoE technology.
The system of video registration can be realized at the level hardware - a program complex and to contain a set of service functions which in many respects will facilitate work with system.
The convenient system of storage of video on hard drives will not bring a lot of trouble due to the lack of need to use a huge number of video films.
We will note the main advantages:
the system based on application of IP - technologies, possesses lower total cost of possession. Use of already existing IT - infrastructure is the reason for that that reduces cost on laying of a cable, and somewhat, costs of the network equipment;
environment of transfer of video data. In IP - system the cable of twisted couple which cost is much lower than the cost of the coaxial cable used in analog systems is used;
the signal transmission is carried out on already existing line of the local computer network with use of the Ethernet/Fast Ethernet standards and a packet transmission of information;
control of functions of management and monitoring will take less time, thanks to the specialized software;
the possibility of storage of the massifs of hard drives which are video given with use will make system of storage more flexible and reliable;
one more advantage of the IP systems - video surveillances - ability to integrate with other security systems. In turn analog systems of video surveillance are less adapted for this purpose.
Thus, using IP - video surveillance, it is possible to realize the desirable level of safety, and also thanks to constantly developing technologies in the field it is easy to modernize and supplement system with more modern ip models - the equipment.
