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.

Q: HD camera is said that his clarity, infrared camera is that it's night vision function, in order to highlight the main features of the name of a: 1, the camera generally talked about the camera, it is natural to think of home cameras. In fact, surveillance cameras and home cameras are many different, first of all fundamentally design standards are different, one for industrial applications and design, one for home use and design, so they work in a long time, the use of the environment The volume is small, the monitoring machine with small size, and the home machine because all the control parts and tape all installed in the same chassis, so the volume to be much larger, and must be on-site manual control, can not achieve remote remote control ; In the key resolution, the home machine is generally about 300 lines in the horizontal, and monitoring machine for the blackboard on the blackboard, the horizontal resolution should be more than 400 lines. The JY-803 integrated color camera, 480TV line center resolution, 1Lux low illumination, with automatic white balance, backlight compensation and automatic electronic shutter adjustment function, built-in 22x optical lens.

Q: What is the abbreviation for monitoring the OLUX on the camera?: The ambient illumination can be divided into several ranges: ultra low illumination (10-2lx), low illumination (10-1lx ~ 10lx), general illumination (10lx ~ 105lx), high illumination (106lx or more). See Table A.1. Table A.1 Environmental Illumination Range Environmental Illumination lx 2 × 10-5 to 2 × 10-4 7 × 10-4 to 3 × 10-3 3 × 10-2 to 3 × 10-1 5 5 × 102 3 × 103 ~ 105 3 × 104 ~ 105 106 Examples of environmental conditions dark night stars moonlight dawn sunrise / sunset cloudy sunny flame

Q: Monitor the camera image virtual how the matter: 3, poor interface. This is generally for the simulation of the BNC interface for a new BNC head to try.

Q: Test on camera delay problems: Test the network infrared camera delay problem is very simple, only need to monitor the camera at high precision stopwatch, so that the reality of the image and display the image contrast, through multiple arrests we can calculate the IPC delay time.

Q: Monitor knowledge! 1.2 m × 20 meters of the corridor with a large angle of the camera the best?: According to my experience, the first with 6mm lens, the second with 3.6 or 4mm lens is better.
