Abstract: In order to satisfy the great demands of high speed and high precision dome cameras in monitoring systems, the design and implementation of the dome camera pan-tilt control system is introduced, which is based on the MSP430 MCU and A3977. Meanwhile, the software andhardware design is presented in detail. The results show that this system has many advantages, such as high speed, high precision, low cost and stable. So it will have the good market application prospect.
