- First determine the problem, of course, is the discharge method: 1. LAN problems arise, then ping the camera's ip address, whether normal,
- Q: Monitor the camera if the power supply to him a large current, pay attention to the current is not the voltage, the voltage is 12V, then what will happen to the camera?
- The voltage is constant, the current is not increased, such as the camera comes standard with the adapter power supply is 12V / 1A, if the switch for 12V / 5A or 10A, 20A power supply is the same, will not have any impact on the camera. The actual operating current of the camera does not increase as the power of the power increases.
- Q: The working principle of the camera with infrared light
- Second, the infrared camera imaging principle In the night vision monitoring system, the conventional approach is to use the visible light, but this way there can not be hidden, easy to monitor the target and other shortcomings, so use less; the current hidden, scientific night vision monitoring Is the use of infrared camera technology. Infrared camera technology is divided into passive and active. Passive infrared camera technology is the use of any substance in the absolute zero (-273 ℃) are more than infrared radiation, the higher the temperature of the object, the more infrared radiation. The most typical of the cameras made with this principle is the infrared camera, but this special infrared camera is expensive and therefore limited to military or special occasions. The active infrared camera technology is the use of infrared light radiation "lighting" (mainly infrared light), the application of ordinary low-light black and white camera, color to black and white camera or infrared low-light color camera, feel around the scene and the environment reflected back to the infrared light to achieve Night vision monitoring. Active infrared camera technology is mature, stable, become the mainstream of night vision monitoring.
- Q: Monitor the camera in the monitor screen appears in the camera 001 what meaning
- One is the name of the video recorder, you can delete the number from the VCR menu, channel settings.
- 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 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
- The smaller the focal length, the larger the field of view, the smaller the number of people in the corresponding picture;
- Q: Monitor knowledge! 1.2 m × 20 meters of the corridor with a large angle of the camera the best?
- 1.2 m × 20 meters corridor with 6mm and above the best number of mm, 3 m × 5 m of the room with the best 3.6. And then according to whether it is necessary to night vision function, choose the camera is not on behalf of the infrared function!
