The application of high-speed dome camera


The application of slip rings in CCTV dome camera


CCTV dome camera integrates PTZ system, communication system, and camera system. The PTZ system is the rotating part driven by the motor, the communication system is the control of the motor and the image and signal processing part, and the camera system is the all-in-one movement.


The core technical problems of the dome camera are three key components of the integrated zoom movement, the precision stepping motor, and the highly reliable transmission slip ring. The high-speed dome camera can rotate 360° unrestrictedly and continuously, and the rotation speed can reach 250-360°/s or more. It requires high running speed, stable running and accurate positioning.

The application of slip rings in CCTV dome camera

The high-quality electric slip ring is a powerful guarantee for the high-speed dome camera to transmit video signals and control signals accurately and accurately while 360 degrees continuously rotating. On the other hand, the high-speed dome camera also needs to transmit a large amount of video data through the slip ring, as well as control signals and other trigger signals. Therefore, when a slip ring is applied to a high-speed dome camera, its stability, reliability, service life and transmission rate are the most important.


3KM LINK CCTV dome camera slip rings is with compact structure, maintenance-free modular design, the brush wire and loop of the slip ring are made of rare precious metal materials, military surface treatment technology, the industry’s original low-wear and corrosion-resistant super-hard gold plating treatment, Eliminates the phenomenon of dust accumulation by brush wires friction, dynamic resistance change value <0.005Ω, meets the needs of ultra-large and ultra-high-speed radio frequency and image signal transmission, with a service life time up to 30 million revolutions, far exceeding the service life of major brands of high-speed dome cameras , to ensure a high level of signal-to-noise ratio, no loss of encoded data, and accuracy of control signals.
