High-speed smart dome cameras are widely used in all-weather security monitoring. After years of development, it has become a weapon of security monitoring. In fact, not only large-scale 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 civilian monitoring systems, and even in residential community monitoring projects. Can be applied, in addition it also in the use of large-area high-definition monitoring applications also played the power of 24-hour monitoring. Why high-speed smart dome cameras can be widely used for such rapid development? To understand this issue, we must first understand the structure and principles of high-speed smart dome cameras.
The high-speed smart dome camera has a high degree of integration and integrates a pan/tilt system, a communication system, and a camera system. The pan/tilt system is a part that relies on a stepper motor to rotate to adjust the dome position; the communication system refers to the motor. The control and the transmission of images and signals; the camera system includes a machine movement. Between the systems, the main CPU processor and the power section play a lateral connection. The power supply supplies power to each system, while the CPU maintains the normal operation of all camera functions.
The evolution of high-speed smart dome cameras does not change much. In detail, high-speed domes use the “differential stepping motor motor†structure to achieve their fast and accurate positioning and rotation, all of which are issued 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, and focus, can be set as actual. Control project.
There are several major hardware components of the high-speed smart dome camera that are worth mentioning. The first is the rotating motor part, then the slip ring, followed by the power supply part and the control board. The drive belt is also very 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 mode refers to what can be accepted on these communication protocols. Ways to control orders issued and communicated. In general, the current high-speed dome cameras adopt many RS-485 communication methods, but each manufacturer is slightly different in communication bits and control character strings.
The above is related to the introduction of the structure and principle of high-speed smart dome cameras. After you read these, you have a preliminary understanding of high-speed smart dome cameras.
