Overview
HCL5-M TDD-OFDM radio module is specifically designed for video data wireless transmission with two way wireless data link. This OFDM radio module operates in the 800MHz, 1.4GHz and 2.4GHz frequency bands, and employs frequency hopping technology (FHSS) to ensure the stablity of signal transmission.

Wireless Networking with HCL5-M Module
The TDD radio module supports two working modes: Access Node or Central Node. It can be managed through Web UI or AT command via uart3. This module can connect up to 16 Access Nodes to one Central Node, and all nodes share a maximum 30Mbps@20MHz throughput bandwidth. Uplink and downlink stream ratio can be controlled through web UI or AT command.
FAQ
Q: This TDD-OFDM radio module seems to support IP camera, what if I want to use a camera with HDMI or SDI video output?
A: For cameras with HDMI, SDI, AHD or AV output, you'll need our mini encoder device to encode the signal for transmission. At the receiver end, connect directly to your computer or NVR. For HDMI monitor output, our decoder device can convert the digital data back to HDMI video and audio signals.
