STARTRC Universal V2 Drone Alarm Tracker For DJI Avata Series Mavic Series Air Series Mini Series (Black) Features 1. This siren, designed specifically for DJI drones, attaches to the drone and functions normally as a strobe light (meets FAA requirements for visibility up to 5 kilometers). It can also function as a siren when the aircraft is in danger. Its audible and visual alarms can be used to locate the drone after a crash. Compatible with DJI Avata, Mavic, Air, and Mini series. 2. Equipped with a 120dB speaker and a 100-lumen LED light, it autonomously controls the siren sound and flash. These alarms will automatically trigger after the drone has been powered on for 10 minutes, after the aircraft has been in the air for over an hour, or if it senses a crash. 3. The siren sounds within a 50-meter range and also features a flashing function. The beeping sound and flashing function at night can quickly determine the drone location. This function can also be used for daily warnings. 4. USB-C Rechargeable Battery for Long Battery Life: The siren is powered by a safe and durable 250mAh polymer battery, boasting a battery life of 15 days in standby mode and up to 4 hours when left on. The Type-C port allows the siren to be fully charged in just 1.5 hours via a USB-C cable. 5. Includes two elastic silicone straps, one for each model. The silicone straps securely attach to the drone, preventing loosening or falling off. The siren can be easily installed and removed from various drones. Note: The V2 upgrade eliminates the need for a phone connection and automatically senses the connection, offering simple, point-and-shoot operation and enhanced convenience. Package List 1.
