Video Transmission refers to the technology of transmitting image and audio signals from the acquisition end to the receiving end through wireless or wired media, which is widely used in scenarios such as security monitoring, UAV image transmission, industrial vision, telemedicine, and live streaming.

An audio module is a modular hardware unit integrated with audio acquisition, processing, encoding, transmission, or playback functions, widely used in scenarios such as wireless communications, smart speakers, intercom systems, in-vehicle audio-visual systems, and security monitoring.

Superheterodyne is a classic radio transceiver architecture first proposed by Edwin Armstrong in 1918, and it remains the mainstream solution for wireless communications, broadcasting, remote control, and other applications to this day.

ZigBee Mesh Network is a low-power, low-cost, short-range wireless communication technology​ based on the IEEE 802.15.4 standard, specifically designed for Internet of Things (IoT) and machine-to-machine (M2M) applications. Operating in the 2.4GHz globally license-free ISM band, it features self-organization

Ad Hoc Network is a distributed wireless network that requires no fixed infrastructure, allowing nodes to dynamically join and leave the network. This architecture completely subverts the traditional wireless communication paradigm, providing flexible, reliable and low-cost solutions for IoT, emergency communication, mobile computing and other fields.

Zigbee 3.0 is a new-generation wireless communication standard released by the Zigbee Alliance (now Connectivity Standards Alliance) in 2016, marking a critical turning point for IoT wireless protocols moving from fragmentation to unification.

Zigbee gateways play a critical role in wireless networks for smart homes and industrial IoT. They serve not only as a bridge connecting Zigbee devices to external networks (Internet, cloud, local servers), but also as the brain and command center of the entire wireless Mesh network.

CAN FD (Flexible Data-rate) is a protocol-layer upgrade of the classic CAN bus, with its physical layer fully backward compatible with legacy CAN infrastructure. This design allows the industry to resolve bottlenecks of classic CAN while avoiding full-scale architecture replacement and controlling upgrading costs.

In today's rapidly developing IoT technology landscape, ZigBee has emerged as a core wireless communication technology for smart homes, industrial IoT, smart agriculture, and other fields, thanks to its low power consumption, self-organizing network capabilities, and high reliability.
