CENO have many kinds of slip ring customized for surveillance equipment. Mainly used in High-Speed Dome Camera, Heavy-Duty Integrated Pan-Tilt Unit and Panoramic/Multi-Sensor Pod.
Slip rings serve as the “lifeline” and “information highway” in surveillance equipment, particularly rotating monitoring devices. Below, I will provide a detailed analysis of their applications, equipment, working principles, and signal transmission requirements. In surveillance applications, slip rings are primarily used in equipment requiring “pan-tilt” functionality—that is, devices needing to rotate freely in both horizontal and vertical directions to achieve wide-area, blind-spot-free monitoring. Examples include high-speed dome cameras, heavy-duty pan-tilt units/integrated pan-tilt heads, and panoramic/multi-sensor pods.
1. High-Speed Dome Camera
Device Description: The most common application, integrating a camera, pan-tilt mechanism, and protective housing into one unit, enabling rapid and smooth horizontal and vertical rotation.
Functions
Power Supply Provides electricity to the camera core, heater, fan, wiper, and other components inside the dome camera.
Control Signals Transmits PTZ commands (Pan-horizontal rotation, Tilt-vertical tilt, Zoom-magnification) and signals for functions like lighting control and defrosting.
Video/Data Signals Transmits high-definition video data (analog or digital) captured by the camera back in real time.
Features
Infinite Continuous Rotation The fundamental value of slip rings, eliminating cable entanglement constraints.
High Integration Typically integrated within pan-tilt drive assemblies for compact design.
High Speed & Smooth Operation Ensures stable contact during high-speed tracking, preventing video flickering or control signal interruptions caused by rotation.
2. Heavy-Duty Pan-Tilt Unit / Integrated Pan-Tilt Unit
Equipment Description Typically deployed in large-scale long-range surveillance scenarios such as military, border defense, maritime, and airport applications. Capable of mounting complex payloads including heavy-duty telephoto lenses, thermal imagers, and laser rangefinders.
Functions
High-Power Supply Provides electricity for high-wattage cooled/uncooled thermal imaging cores, high-intensity searchlights, lasers, and similar equipment.
Multi-Channel Complex Signal Transmission Simultaneously transmits multiple video streams (visible high-definition, thermal imaging), high-speed serial data (e.g., Gigabit Ethernet), precise servo control feedback signals (encoder signals), and sensor data.
Features
High Power Capable of transmitting hundreds of watts or even kilowatt-level electrical power.
Multi-Channel, High Bandwidth Integrates power rings, signal rings, and high-frequency data rings (including fiber optic slip rings) into a single unit, representing a typical application of a combined slip ring.
High Environmental Adaptability Requires waterproofing, dustproofing, resistance to extreme temperatures, and salt spray resistance to withstand harsh field conditions.
3. Panoramic/Multi-Sensor Pod
Device Description Designed for mobile platforms such as drones, vehicles, and vessels, it integrates multiple fixed or movable sensors internally.
Sleeve Function Enables stable rotation of the pod housing relative to the mounting platform while providing stable power and data pathways for all internal sensors (e.g., multispectral cameras, LiDAR, communication antennas).
Features
Extreme compactness and lightweight design Critical for UAVs where weight and volume are paramount.
Ultra-high-speed data transmission Handles demanding bandwidth requirements like LiDAR point cloud data and high-frame-rate video streams, often utilizing fiber optic slip rings.
High vibration resistance Withstands continuous vibrations from aircraft or vehicle movement.
