Custom Case of Anti-shake Filter Inductor Coil for Security Cameras

Outdoor PTZ security cameras work 24/7 in open-air environments, equipped with filter inductance coils and anti-shake drive coils for image stabilization, power filtering and lossless video signal transmission. Affected by thunderstorm surge, grid voltage fluctuation and outdoor electromagnetic interference, common coils have weak anti-interference and lightning resistance, which easily cause image jitter, screen noise, camera restart and coil breakdown, resulting in invalid monitoring footage and high equipment maintenance cost.

The client is an original security camera manufacturer exporting AI PTZ cameras, POE waterproof cameras and explosion-proof monitoring devices to Europe, Southeast Asia and other overseas regions. Its new 4K camera failed overseas EMI lightning protection certification, for the original coils could not filter outdoor clutter and had low surge resistance. The client needed customized anti-shake filter coils with high voltage endurance, UV aging resistance, stable inductance value and EMI compliance for overseas security standards.

Fuying Electronics adopts UV-resistant magnetic core and double-layer insulated thickened enameled wire to improve lightning surge resistance and outdoor aging resistance. The hierarchical staggered winding structure optimizes clutter filtering and power stabilization performance to eliminate screen noise and flicker. Reinforced winding structure adapts frequent PTZ rotation operation to avoid wire breakage. Every coil passes EMI simulation test, lightning withstand test and inductance calibration to meet overseas certification requirements.

Equipped with our coils, the 4K cameras deliver stable anti-shake imaging, clutter-free video and zero breakdown in thunderstorm weather. All camera models pass overseas EMI and lightning protection certification smoothly, with after-sales failure rate reduced by 88%. We supply customized filter coils and PTZ drive coils for civilian and industrial security cameras, supporting international standard parameter customization.
