AirLink — 4G/5G AI Camera · Wi-Fi HaLow · Cloud Platform

Wi-Fi HaLow (IEEE 802.11ah) is a long-range wireless standard that operates on sub-1GHz frequencies (typically 915MHz), unlike conventional Wi-Fi which runs on 2.4GHz or 5GHz. This lower frequency gives it two critical advantages for surveillance: signal range and obstacle penetration. A Wi-Fi HaLow access point can transmit up to 3km in open environments, compared to 100–150m for standard Wi-Fi. The sub-1GHz signal also passes through walls, vegetation, and building materials far more effectively than conventional Wi-Fi, making it suitable for large outdoor areas, farms, construction sites, ports, and industrial campuses. In a typical HaLow surveillance deployment, one or more HaLow APs are installed at a central point. IP cameras — including PTZ and bullet camera models — connect wirelessly over distances that would require expensive cabling or cellular data with standard technology. Video streams are transmitted back to an NVR, cloud platform, or monitoring station over the HaLow network. AirLink's Wi-Fi HaLow product line includes 100mW, 1W, and 2W access points, and HaLow-integrated cameras covering bullet, PTZ zoom, smoke/fire detection, and facial recognition applications. All models support ONVIF and RTSP protocols, and are compatible with third-party NVR systems. Key advantages over cellular (4G/5G) for fixed surveillance sites: no SIM card, no monthly data cost, no carrier dependency.
