Q:Camera clarity, 1080p. 3mp. 4k, what does it mean

1080P that is 1920 × 1080 resolution, progressive scan (equivalent to two million pixels)

Q:Monitoring camera 6mm 8mm 12mm 16mm length and width can be according to how much.

At the same time, the same focal length, length and width shooting range also with the camera CCD has a relationship. Charge - coupled Device, Charge - coupled Device. It is a semiconductor device that converts optical images into electrical signals. At present, most of the CCD chip used in the surveillance camera is 1/3 "and 1/4", that is, the target size is 1/3 inch and 1/4 inch. CCD target surface size, CCD and lens with the situation will directly affect the size of the field of view and image clarity.

Q:What is the difference between a camera's double point and a single lamp point?

Array infrared camera in the field of monitoring the application of the biggest advantage is to solve the problem of LED light source cooling, with high luminous efficiency and luminous intensity, photoelectric conversion efficiency than ordinary infrared LED camera increased by about 25%, the efficiency can reach 45% Greatly reduce the energy consumption, increase the lighting distance, while extending the life of the camera, array infrared night vision camera life is generally 9 times the life of ordinary infrared camera.

Q:Home surveillance camera with which brand is good?

But recently they saw their home out of the new monitor, baby monitor, the family can consider a child ah, in fact, this can also monitor the child, but that part of the function is for the children. Can choose according to their own needs.

Q:Monitor the farthest distance from the camera can be far, which manufacturers out

The effective distance of the surveillance camera is determined by the lens focal length used, and there is no direct relationship with the manufacturer. Surveillance cameras on the market effective monitoring distance is generally in the five meters to 150 meters.

Q:Digital surveillance camera how to increase? Each head of the ip are 192.168.1.10 now have ten cameras. Ask how to do?

Modify the last two digits of each camera is like a 192.168.1.11,192.168.1.12, ...

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.
