Powerhouses Join Forces: Panlink's Capsule Slip Ring Empowers Hikvision's Dome Camera with HD Vision and Stable Performance

Client: Hikvision
Industry: Security & Surveillance
Application: Pan-Tilt-Zoom (PTZ) Dome Cameras
Solution: Panlink Customized Capsule Slip Ring

Project Background and Collaboration Opportunity

As a global leader in security solutions, Hikvision (HIKVISION) set extremely high requirements for a core component—the conductive slip ring—in the development of its new generation of high-definition dome cameras. The slip ring needed to achieve stable, lossless transmission of HD video signals, control data, and power within a limited space, while also supporting the camera’s pan-tilt mechanism for 360° continuous rotation to ensure seamless, blind-spot-free monitoring.

Leveraging its technical expertise in precision conductive slip rings, particularly the compact design, low electrical noise, and high reliability of its Capsule Slip Ring (PSR-M/K/C Series), Shenzhen Panlink Electronic Technology Co., Ltd. partnered with Hikvision to provide a customized slip ring solution for their dome cameras.

Solution: Application Highlights of Panlink's Capsule Slip Ring

To meet the technical requirements of Hikvision's dome cameras, Panlink provided the following solutions:

1. Lossless Transmission of HD Signals

Panlink's capsule slip ring supports the transmission of HD video signals such as 720P, 1080P, 1080I, and HD-SDI, with a maximum transmission rate of up to 3Gbps/3GHz or even higher. Its unique gold-to-gold contact design and shielding anti-interference structure effectively ensure the integrity and real-time performance of raw HD video data during rotational transmission, avoiding issues like image smearing or distortion.

2. Compact Structure and Smart Integration

The capsule slip ring features a cap-like shape with an integrated flange, offering a compact structure and small size (available in various outer diameters ranging from 9mm to 22mm). It perfectly adapts to the limited internal installation space of Hikvision's dome cameras, resolving the common problems of tangling and wear associated with traditional wiring methods during rotation.

3. Hybrid Signal Transmission with Stability and Reliability

This slip ring not only transmits HD video signals but also supports hybrid transmission of power. Utilizing precious metal contacts and precision engineering, it delivers low torque, low loss, and maintenance-free operation, ensuring the camera's stability and extended service life even during long-term high-speed rotation.

4. Low Electrical Noise for Enhanced Image Quality

The capsule slip ring exhibits extremely low electrical noise (as low as 10mΩ), effectively reducing electromagnetic interference (EMI) during signal transmission. This provides backend devices with a cleaner signal source, thereby improving overall image quality.

Results and Value Enhancement

By adopting Panlink's capsule slip ring solution, Hikvision's dome surveillance devices have achieved significant improvements:

• Superior Image Quality: Uncompressed raw HD video data is transmitted stably, delivering clear and smooth footage that meets the high demands of security monitoring for real-time performance and image quality.
• Enhanced Stability and Durability: The slip ring's low resistance and wear-resistant contact design significantly reduce failure rates and minimize maintenance needs, ensuring reliable long-term operation even in complex environments.
• More Efficient and Flexible Design: The compact design simplifies the internal structure of Hikvision's dome cameras, reduces overall power consumption, and enables greater potential for product miniaturization and functional integration.
