Security Surveillance Cameras Hitech’s security surveillance camera is an HD analog camera using the mega-class CMOS which shows more excellent image quality than the analog CCD sensor. The camera features a high definition of 5 megapixels even with an analog not digital and it shall output at a maximum frame rate of 20 frames per second at a resolution of 2592(H) x 1944(V) active pixels.
The 5-megapixel-level of CCTV camera developed by Smabo Hitech has many advantages. Equipped with infrared LED, this camera offers a clean image quality at night time, generates little heat by reducing the power usage even when the infrared LED is on, and is composed of the module having a stable circuit that can maintain high definition even in long-distance transmission of longer than 300 meters.
Considering that a lot of heat affects the image quality and, as a result, causes loss of image quality in long-distance transmission, the company has composed a circuit so that power consumption can be low even in the product that has used many IR LEDs in order to avoid quality degradation in any circumstances. In addition, to use infrared LED, this camera is designed to be able to use the varifocal lens (having the functions of automatic iris control and ICR together), enabling zoom-in and zoom-out to be controlled.
In addition, there is also a camera using a motorized lens. If you focus the high-definition camera manually, there may be errors incurred in minute details. However, there is also a camera that can show you sharp pictures in complete focus even with 5 million pixels by using a motorized varifocal lens that can adjust the focus automatically. This camera, using an IR-CUT removable filter, provides an image which shows the colors of the visible light region accurately in the daytime by blocking the ultraviolet light and shows a vivid and clear picture of black and white at night by making the picture pass through the infrared ray coming from the infrared LED. In addition, with the Smart IR function, the camera does not saturate the infrared rays shed at night into one spot and compensates the black and white image of the night time vividly.
With the 5-megapixel camera, you can output three types of signals including AHD, HD-TVI or analog CVBS selectively and, in this case, the aspect ratio becomes 4:3. In addition, the pixels are changed into 4-megapixels, you can output four types of signals including AHD, HD-TVI, HDCIV or analog CVBS selectively with the aspect ratio of 16:9. Various 5-megapixel level cameras are prepared, such as a box camera, a dome camera, a semicircular dome camera, an infrared camera, a miniature camera, etc. | Blog Magazine of korean electronics, brands and Goods
