Article aims to look into the issue of IP CCTV (IP CCTV). I introduce gun safe the basic division in terms of standards EN 50132-1, which after the last update respects and IP video. Describe the fundamental differences in the architecture and characteristics of classic analog and IP camera systems. Furthermore, after further gun safe describes the function blocks and the basic elements of IP CCTV, their properties and performance. gun safe
The development of information and communication gun safe technologies has meant that these have become much more affordable for small and medium businesses. Computer networks are no longer capable of transmitting not only data, but also video and audio, and this helped to very rapid and dynamic development of IP camera systems, which are compared to traditional analog CCTV capable of offering new possibilities and uses. New opportunities that we can offer IP CCTV is countless, but this may result in even greater complexity of the system gun safe in terms of design.
The basic difference IP CCTV over traditional analog CCTV is just in a different system configurations. Analog systems gun safe are in a fixed structure camera - recording equipment gun safe - monitor very limited, mainly because they use rather outdated PAL television standard which, for reasons of compatibility TVs lags and limits the maximum resolution of 720 576 Despite this limit is not the classical gun safe analog cameras did not get. The result, therefore, then, is that IP cameras are able to offer up to 10x higher resolution and more. In practice it can mean the difference between visibility of characters and face recognition proves the alert. IP systems are more general structure, particularly given the number of variants they bring.
The system architecture is simpler, mainly because gun safe it is not needed, no complicated settings. Mostly everything works on the principle of "plug and play", which means that you only need to connect the camera power cables for video transmission and recording on the connected device and I can see right picture. These systems mostly for smaller installations where the distance from the camera recording equipment to about 300 m, based on a much cheaper. With appropriate deployment of cameras and the correct choice of perspective can adequately serve its purpose and at a much lower price than the variant IP cameras gun safe with high resolution, which in this case may not be needed at all. The camera image-sensing chip is converted to an electric digital signal, and this is then D / A converter to a signal of the analog. The path-to-analog signal is transmitted according to the type of transmission (wired / wireless) for further image processing equipment. By default, the signal is not encrypted. Recording equipment-analog signal is digitized and recorded on the HDD, Display-image information is displayed either live or played from the HDD. You already most storage devices and allows you to connect to your network and remote access to the system, which already gun safe allows integration with IP CCTV and a single gun safe camera system.
These systems gun safe can no longer be clearly separated into individual functional blocks as analog: It is for this reason that everything can happen in the camera (remove the image / transmission line / record) or it can be for example used so that an image of ensuring IP camera, the image is transmitted through transmission computer networks gun safe in business and recorded on the company server. Therefore, the distribution according to EN 50132-1 more general. Environment Video Image Capture transfer video information and other information recording, viewing, image analysis system management - management of data and activities, links to other systems Security System Integrity system - fault detection, protection against physical disruption, protection against gun safe unauthorized access to system data integrity - data identification, gun safe data authentication, data protection
The longer we focus on a single point Video environment, which describes a distributed elements, functions and features of IP CCTV to IP video surveillance gun safe system may include, as required for the physical implementation of the system.
Is converted image on a video signal which is then compressed and ready for transmission over a network. The image information can, be other information that directly evaluates gun safe the IP camera and are attached to the image. This may be a sound alarm input information from cameras, camera information evaluated. Options embodiment gun safe of the device to capture the IP image are as follows:
It is the basic and most used element, the main feature is that it captures the image of the monitored area, compresses the image to transfer the com
