Real-world range varies with wind, terrain features (forest absorbs sound, open water carries it further), and background noise levels at the receiver location. Urban environments, industrial sites, and high-wind conditions reduce effective range.\u003c\/p\u003e\n\n\u003cp\u003eFor SAR operations specifically, the AS1's most reliable use case is direct communication with a known-located subject at a known distance, not broad-area calling out across an unsearched terrain. For the latter, ground-team callouts combined with thermal detection are more effective than aerial speaker broadcasts.\u003c\/p\u003e\n\n\u003cp\u003eFor law enforcement use, verify with your agency's legal counsel that broadcast from an aerial platform meets your jurisdiction's announcement and warning requirements for the specific operational context (compliance order, evacuation, perimeter announcement). The AS1 is a tool, not a legal substitute for ground-team contact in situations where direct contact is procedurally required.\u003c\/p\u003e\n\n\u003ch4\u003eProtection and Coverage\u003c\/h4\u003e\n\u003cp\u003eThis is genuine DJI hardware.
