DJI AL1 Spotlight for Matrice 4
The DJI AL1 Spotlight supports two modes: always-on and strobe. It can clearly illuminate subjects even from a distance of 100 meters. Additionally, it can intelligently link with the gimbal, following the camera's movements to ensure the illuminated area matches the camera's view. It also offers a wide FOV lighting mode, which can light up a broader area when in wide-angle mode. The spotlight and speaker can be used independently or in combination, meeting the needs of more operational scenarios.
