The structure and principle of high-speed smart dome camera

The high-speed smart dome camera is widely used in all-weather security monitoring. After years of development, it has become a weapon for security monitoring. In fact, not only large supermarkets, gas stations, banks, airports, government agencies and other important departments use high-speed smart dome cameras, but they are also widely used in general civil monitoring systems, even in residential area monitoring projects. It has been applied, and it has also exerted the power of 24/7 monitoring in some high-definition surveillance applications that require large areas. Why is a high-speed smart dome camera widely used for such rapid development? To understand this problem, you should first understand the structure and principle of a high-speed smart dome camera.

Smart dome camera

High-speed smart dome camera structure and principle:

The integration of the high-speed smart dome camera is quite high, integrating the pan/tilt system, the communication system and the camera system. The pan-tilt system refers to the part that relies on the stepping motor to rotate to adjust the direction of the fastball monitoring; the communication system refers to the motor The control and the part of the image and signal transmission; the camera system includes the integrated machine movement. Between the systems, the main CPU processor and the power supply unit play a horizontal connection. The power supply supplies power to each system, while the CPU maintains the normal operation of all camera functions.

The evolution of the high-speed smart dome camera has not changed much. In detail, the high-speed ball uses the "differential stepper motor motor" structure to achieve its fast and accurate positioning and rotation, all of which are sent by the CPU processing chip. The instructions are executed, and then the camera's image and control functions are written into the RAM memory in the high-speed ball movement, and many functions of the camera, such as white balance, shutter, aperture, zoom, focus, etc., can be set to actual. Control the project.

There are several main hardware parts of the high-speed smart dome camera that are worth mentioning. The first part is the rotating motor part, then the slip ring, then the power supply part and the control board. The drive belt is also important. The communication part refers to the communication protocol and the protocol. The communication protocol refers to the communication content code mode selected when the high-speed ball communicates with the host system. The communication protocol means what can be accepted on these communication protocols. Ways to make control orders issued and communicated. Generally speaking, the current high-speed dome cameras adopt RS-485 communication methods, but the manufacturers are slightly different in communication bits and control character strings.

The above is about the structure of the high-speed smart dome camera and its principle. After reading these, do you have a preliminary understanding of the high-speed smart dome camera.
