Video signal converter and other similar devices.
There is no need to talk about the need to connect additional devices (such as a video surveillance cable) in order to improve the quality of the video signal, so we will limit ourselves to describing the most commonly used methods in practice today.
Video signal converter
Video signal converteris used mainly to connect additional monitors of the video surveillance system and to obtain a full signal as a result. In addition, joint switching of audio and video signals is possible. Video signal converter allows you to increase the power of all channels. The converter module is equipped with an input for external video signals, which allows you to support various formats. As a rule, the device can be used for analog-to-digital or digital-to-analog conversion of component video signals. Video signal converterhas a synchronization circuit based on a reference video signal and a built-in test signal generator. Modern equipment of this kind is designed in such a way that there is always the possibility of subsequent modernization, addition and improvement of the modular design in the event of the emergence of new formats of audio and video signals. The set with this device includes a remote control that regulates the image quality (sharpness, brightness and contrast), allowing you to enlarge a specific area of the image. Video signal convertercharacterized by small dimensions and weight, also comes with a network power supply and video cables.
Video signal splitter
A video signal splitter is used to expand the functional potential of the video surveillance system.. The device allows access to computers from a remote control console, which is convenient in conditions where the console must be placed in an accessible and convenient place for the operator, and the system devices in a safe place, away from dust, dirt and harmful environmental influences. Video signal splitter allows the system to be placed at a distance of about 150 meters from the console. One of the components of the equipment is an extender, which must provide a high-quality connection to the remote system unit of the computer. Video signal splitteris a video splitter that functions as an amplifier and video signal divider, which receives a signal as an input from one source and supplies it as two or four output signals to analog monitors. Signal amplification allows not only to split the signal, but also to increase its transmission distance by several meters. Thus, it becomes possible to broadcast from one computer, which is necessary in the implemented video surveillance systems.
Video signal converter
Video signal converteris designed to convert video signals with sound from analog to digital quality and vice versa. You can simply connect a digital camera to a computer using an adapter and start editing. The adapter is already built into many boards. In terms of cost, this device is one of the most inexpensive among other auxiliary devices for video equipment.
Video signal converter performs the functions of encoding and decoding the signal, minimizing image defects. As a rule, it is used together with video recorders that do not have a VGA output.
Standard video signal converter supports the following signal formats: standard composite video signal, S-video, VGA. Has an external power source. To operate, the device requires software or installation of drivers. The use of modern signal processing technologies guarantees the absence of any losses when converting information from low-frequency video, S-VIDEO and VGA video inputs into a VGA signal.
