core components of surveillance camera?
During the cooperation consultation, people often ask about the service life of the camera module or camera. Today I will give you a brief explanation:
First of all, let’s understand the composition of the surveillance camera: the surveillance camera mainly consists of 4 large accessories and 3 small accessories.
Large accessories: camera chip, lens, lamp board, shell.
Small accessories: tail wire, lens holder, copper pillar, vân vân.
Camera chip:
The core component of the surveillance camera is the chip, which is equivalent to the camera brain. The chip is embedded on the motherboard, so it is also called the camera motherboard, which is divided into CCD motherboard and CMOS motherboard. Two important parts of the chip are: imaging sensor and chip processor.
Camera lens:
The camera lens can be divided into large lens and small lens in terms of appearance.
Key knowledge of lens: focal length and aperture.
Focal length: It refers to the number of millimeters of lens we usually talk about. Generally 4mm, 6mm, 8mm, 12mm, vân vân.
Aperture: the F value on the lens, generally F1.0, F1.2, F1.4, F1.6.
The larger the millimeter number of the lens, the smaller the viewing range and the farther the distance. Ví dụ, the workshop and warehouse usually use 4mm lens; The unit door of the building in the residential area is usually 6mm; According to the fence, the path is usually 12mm, which is not absolute, but should be selected and used flexibly according to the specific scene. The smaller the F value of the aperture, the greater the luminous flux, and the more expensive the lens is.
Camera light panel:
Common camera light panels are: array type infrared lamp, ordinary infrared lamp and white light panel.
The function of the light plate is to provide an auxiliary light source for the lens at night, so that the lens can sense infrared light and become an image. If the light panel delivery effect is not good for various reasons, it can also be equipped with an auxiliary light source separately.
Camera housing:
There are many shapes and styles of camera shells, which are generally divided into gun models, hemispheres, balls, vân vân.
It can be divided into aluminum, plastic, vân vân.
The specific situation shall be subject to the requirements provided by the manufacturer. But elaborate more.
Camera life:
Under normal environmental use conditions, excluding the influence of human factors, the service life of the surveillance camera with infrared (infrared decay and aging are relatively fast) is 3-5 years. After three years, the image definition will begin to decline. The image definition of ordinary cameras will decline seriously after more than five years. It is difficult to perform monitoring tasks again, so the equipment should be replaced in a timely manner.
The service life of the surveillance camera without infrared is relatively long, up to 10 years. With the maturity of infrared technology, the service life of the infrared camera has been extended. The specific service life is also related to protection measures, application scenario environment, regional weather conditions and other factors.
