    Proper Surveillance for the Proper House Protection

    If you plan to install wireless surveillance, there is no need for a power supply for video cameras and wiring. For a home video surveillance system, a monitor is also not required, as the control of an apartment or a private house is conducted by the owners remotely via the Internet. Remote video monitoring allows watching children, as well as for sick or elderly relatives.

    If permanent video surveillance is not required, you should purchase and install video cameras equipped with motion sensors, the triggering of which leads to the inclusion of the recording mode of video information. In addition, upon the triggering of sensors, the system warns the owners of unauthorized intrusion and can signal the alarming rapid reaction group. The good at cctv Singapore option is perfect there.

    Choice of equipment

    Camera – the basis of the system

    The main element of any surveillance system is a video camera. It is on its parameters that the quality and reliability of video surveillance depends. Of course, for an ordinary apartment, you do not need to buy a luxury camera with the highest resolution and detail, which cost a lot of money, but you do not need to save on home security either.

    The main parameters of video cameras:

    • Sensitivity
    • Resolution
    • Useful signal to noise ratio

    Lens Capture Angle

    The sensitivity unit of video cameras is Lux (lx). This parameter determines the minimum level of illumination at which the camera will broadcast a sufficiently distinct image. So the sensitivity of the camcorder to 0.01 lx will allow seeing the image of the night landscape on a moonless night. In residential video surveillance systems, cameras with a sensitivity of 0.05 to 0.1 lux are usually used.

    In addition to the useful signal, any video camera generates a noise signal, the value of which should be as small as possible, since it clogs the main video signal. The noise on the monitor screen will be visible in the form of ripples or snow. The reliable singapore home improvement option is there now.

    This parameter is measured in decibels and for video cameras used in surveillance systems, it must be at least 45 dB. The signal to noise ratio of 48 dB is considered a very good indicator for CCTV cameras.

     

    The viewing angle of the video camera determines the controlled area of ​​the room or territory. This parameter depends on the focal length and the size of the photosensitive matrix. It should be noted that the smaller the focal length, the larger the capture area. There are cameras used in video eyes that give a viewing angle of 120 0. They capture a large area, but the image is very distorted, especially at the edges, so they are not used in video surveillance systems.
