How the security camera works

The security camera works as follows:

Optical sensor

The security camera is equipped with an optical sensor that can generate electrical signals by capturing light. When an object enters the camera’s field of view, the light is reflected onto the sensor, creating an electrical signal.

Image processing chip

The camera converts electrical signals into digital signals and processes them through the image processing chip. The chip can denoise, enhance and compress the image to make the image clearer.

Data transfer

The processed image data is transmitted to the display device or storage device through a network or wired connection. This allows users to watch the live video or replay the recorded video.

Control system

The security camera is usually equipped with a control system that can adjust the parameters of the camera, such as brightness, contrast, focus, through the user interface or remote control.

Software analysis

Some advanced security cameras are also equipped with a software analysis function, which can automatically detect and identify the target objects in the image, such as faces, license plates, etc. These functions can help the monitor personnel to quickly detect abnormalities and take measures accordingly.

To sum up, security cameras use optical sensors to capture images, processed and transmitted to display the images to the user. Through the control system and software analysis, users can adjust and monitor the camera to realize the function of security monitoring.
