CCTV Installers

When choosing the right camera model is often guided by the possibility of adjustments to various operating conditions. Of course, more advanced models have more capabilities, simpler devices keep some parameters fixed.However, to take full advantage of the data set, refer to their action, the impact of the quality of the picture, what positive and negative. Such knowledge will help you achieve the best practical result of the camera.The impact of changes on the example of ACTi cameras, but they refer to other types of cameras from different manufacturers.Resolution The basic parameter demonstrating the quality of the image is the resolution. It tells about how many points made up the whole picture. Obviously, the higher the resolution, the better the image quality, or a larger area monitored. In contrast, this entails also a greater demand for bandwidth and increases the volume of recorded material. Popular this CIF resolution (320 x 240), VGA (640 x 480), D1 (720 x 576), SXGA (1280 x 1024), UXGA (1600 x 1200), etc.Comparison of typical resolutionrate Parameter talking about how many frames are transmitted per unit of time. The more the image is smoother. In a televised PAL is 25 frames per second, which is considered as an image without effect poklatkowoĊ›ci. However, in practice, the 25 frames, and only 5 to 10, which is due to less demand for bandwidth, and the lack of requirement for greater speed. Of course, in special cases need high speed, even at 100 frames per second, but such solutions are not popular. Reduced speed is used to control the crowd, higher (25) to control the behavior of...

If this option is not a good way is a notch in the wall of circle-hole saw room for wires and then cover the hole the camera itself. In this way, fixed camera may deserve to be called a vandal in another case assembly is pointless. Installing the camera (mounting height) A very important factor is the mounting location of the camera. First, avoid mounting heights greater than 4 m and possibly as low as possible. Mounting height has tremendous impact on image quality and viewing angle. A camera mounted at a height of 8 meters indeed be difficult to destroy but will...
