Q:Outdoor surveillance camera what brand good ah

According to the use of the camera environment, can be divided into: outdoor night vision infrared ball, outdoor intelligent high-speed ball, outdoor night vision wide dynamic, backlight compensation, automatic white balance, and so the search function bolt, hemisphere and so on.

Q:Monitor the camera's focal length how to choose?

Second, in the choice to buy surveillance cameras at the same time, for the practical application is also essential, such as civilian-level surveillance cameras, in the same product will be divided into 3.6mm, 4mm, 6mm, 8mm, 12mm and so on different specifications of the lens indicators. These are the user to measure the size of their own needs, such as the use of 3.6mm lens, this is wide-angle lens, look at the scope of a wider, suitable for small space (elevator, etc.), often in open space, wide-angle lens may not be able to See the face, in order to see the face you need to choose the focal length and then some of the larger lens, the so-called telephoto lens, more suitable aisle or corridor, etc., of course, choose how much focal length of the lens have to see the distance to be monitored The. The focal length is bigger, and the range of images you want to see is smaller than you see now.

Q:The working principle of the camera with infrared light

First, the characteristics of infrared and infrared light light is an electromagnetic wave, with the same nature as the radio waves. Its wavelength range is from several nanometers (1nm = 10-9m) to about 1mm (mm). The visible wavelength is from 380nm to 780nm, the wavelength of visible light from long to short into red, orange, yellow, green, blue, blue, violet, the wavelength is shorter than the purple light, the wavelength of visible light is only a part of the visible light, visible light Called ultraviolet light, the wavelength is longer than the infrared light called infrared light. Infrared light wavelength between 780nm ~ 1000μm, located between the radio and visible light. Infrared light according to its infrared radiation mechanism is divided into semiconductor solid light (infrared emission diode IR LED) infrared light and heat radiation infrared light two. At present in the CCTV infrared camera in the former use more.
