Cameras with FDP Link: An Introduction
The demand for high-performance cameras capable of delivering high bandwidth, long-distance transmission, and reliable imaging has grown significantly. FPD Link cameras have become essential for applications such as autonomous driving, object detection, and inventory management. These cameras offer high-resolution imaging, real-time communication, and robust security features, enabling seamless integration and superior functionality across diverse environments.
What Is an FPD Link Camera?
FPD Link, short for Flat Panel Display Link, is an advanced communication protocol and a digital video interface designed to streamline data transmission in automotive and industrial applications. Unlike conventional methods, FPD Link enables simultaneous high-speed video, audio, and bidirectional control signal transmission over a single coaxial cable or twisted-pair cable topologies. Using a serializer in the camera module to deserializer on the host ECU, it supports data transmission over distances of up to 15 meters or more with minimal latency, FPD Link ensures high performance with secure automotive-grade connectors, making it ideal for use in automotive cameras for applications in ADAS (Advanced Driver Assistance Systems).
In ADAS, FPD Link cameras utilize high-speed interfaces to transmit image and video data to processing units, ensuring real-time, high-resolution video transfer with exceptional reliability even in challenging automotive environments. These cameras play a critical role in enhancing system capabilities such as object detection, lane guidance, and obstacle avoidance.
