- 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:Monitor the camera lens focal length is what the situation according to the scope of the big focal point what the situation according to the clear
- Dome cameras generally have 2.5mm, 3.6mm, 6.0mm.
- Q:Why mobile phone surveillance camera is always not online
- Can be connected to the switch through the NVR recorder, the use of the display connected to the video recorder can be seen at any time to monitor the recorded screen images, remote users can log on IPC domain name to IPC to watch, control, management and video. Remote user login IPC can be through the web browser (IE) and the corresponding video centralized management software to achieve, the operation is very convenient, so that you can use the normal network camera.
- Q:What is the power consumption of the camera day?
- According to the DC power conversion efficiency of 80%, the input power = 18W / 0.8 = 22.5W
- Q:The monitor camera does not display the image on the display
- If the power is turned on, but the display no image display, is a blue background and "OFF" words, then the display menu to open the corresponding channel can display the image out.
- Q:What's the difference between monitoring the camera and the usual?
- Monitoring the installation of the camera, generally need to use a few meters to tens of meters ranging from the transmission distance, but in accordance with the provisions of the USB standard, USB device, the longest transmission distance is 5 meters, so USB can not be used for long distance, that is, we use USB camera to do the first problem encountered monitoring. While the 75-5 / 128 video cable can transmit signals over long distances! (Up to 400 meters).
- Q:Monitor the camera gray screen
- 2, the camera itself quality problems. Now a lot of domestic miscellaneous brand camera, the background running program is very poor, resulting in excessive heat of the camera, over time, there will be a variety of problems. The general situation is color black and white. Suggestions for hundreds of pieces for a good brand, for example: like a cottage Apple phone and the middle of the gap between Apple.
- Q:What is the minimum illuminance indicator of the surveillance camera?
- Therefore, the use of different F value of the lens, the camera's minimum illumination value of the determination will have a decisive impact. Second, the light source color temperature. The color temperature is an indicator of the light wavelength content in the light source. A 3200K light source is mostly between 600 nm and 900 nm, and a 9300K light source is between 300 and 500 nm, so the different color temperatures will change completely Test Results. On a typical CCD sensor, a light source with a wavelength of 600 nanometers will produce 10 times more electrons than a wavelength of 900 nanometers. This is why the color temperature is particularly marked for the meaning of the minimum illumination measurement results.
- Q:Is there a surveillance camera that can be plugged in
- Oh, the first kind of camera is generally by the lens, image sensor, analog / digital converter, image control And other parts of the composition, if the audio function, then, coupled with the sound collection, processing and transmission components.
- Q:Monitor the use of the camera
- Depends on what you use, the use of more than 1. to prevent the occurrence of traffic accidents. For example, on the highway if there is no monitoring of the camera monitoring, some people will drive speeding, resulting in traffic accidents, which will
