Monitor the type of camera

At present, the security monitoring market, a wide range of surveillance cameras, dazzling, in order to allow more customers to monitor the type of camera has a new understanding of this to do a simple classification, the current use of surveillance cameras and work Principle is divided into two camps, analog surveillance cameras and network surveillance cameras.

First, the type of analog surveillance cameras

1, according to the general image sensor can be divided into two types: CCD camera and CMOS camera, CCD chip camera in the imaging effect will be better than the CMOS chip, the price is relatively high. Another CCD chip is divided into SONY CCD and Sharp CCD, that is, we often hear the meaning of Sony chips and Sharp chips.

2, according to CCD size can be divided into: 1 / 2CCD, 1 / 3CCD, 1 / 4CCD, refers to the CCD chip photographic area size, the larger the visual range.

3, according to the definition can be divided into: 420 lines, 480 lines, 520 lines, 540 lines, 600 lines, the higher the number of lines, see the clarity is higher

4, according to the function and appearance can be divided into: infrared camera, hemisphere camera, gun camera, explosion-proof camera, PTZ camera, zoom camera, flying saucer camera, smoke camera, etc., are generally installed according to the installation environment use.

5, according to the camera's illumination (lux) can be divided into: 1lux, 0.5lux, 0.1lux, 0.01lux, 0.001lux or lower illumination, the lower the illumination that the camera reflected in the lack of light when the screen effect The more clear, the other is called an infrared camera, up to 0lux, that is, without the case of light can clearly see the object, according to the infrared light irradiation distance can be divided into 10 meters, 20 meters to 100 meters.

Second, the network surveillance camera classification:

Network monitoring camera classification in addition to the clarity of the expression and the simulation is not the same, the other basic can be applied. As the network monitoring camera and analog camera used in different ways, is a digital camera, so people are more willing to distinguish between the resolution and classification, according to the resolution can be divided into: CIF (10 million pixels), D1 Only 720P or more to belong to the high-definition network camera, 720P the following is the standard definition network surveillance camera (standard definition), 720P (100 million pixels), 1080P (200 million pixels), there are 300 million pixels, 500 million pixels, 800 million pixels; .

The above description is only for the surveillance camera for a brief description, for more information on the surveillance camera, please contact me and we will be happy to help you!
