The AOISUN MLV3D has transformed our airport security operations. This all-in-one payload combines 300m voice broadcast, 150m night searchlight, and dual-color warning lights perfectly for our patrols. The 120dB sound cuts through runway noise easily, and the TTS function lets us quickly broadcast evacuation alerts in both male and female voices. The stabilized 2800Lm searchlight tracks our camera angle flawlessly, illuminating runways at night with 0-100% brightness adjustment. The 1000m visible warning lights keep our drone visible to aircraft, even in low light. At just 266g, it’s lightweight enough for our DJI drone, and the Pilot2 integration makes control seamless. It’s operated reliably in -10°C winter mornings and 50°C summer afternoons—truly an all-weather workhorse for airport safety!
