II.
czi LP12 searchlight & broadcasting system is a two-in-one payload
specially designed for the DJI M30. LP12 is with a streamlined
aesthetic design concept. It challenges the limits of performance
while maintaining artistic taste and effectively reducing wind
resistance to enhance the endurance of the drone's flight operations.
The LP12 is the most efficient lighting and sound broadcasting
product up to now of czi, combining the imaging optics of the GL
Series gim bal s earchli ght wit h the LRAD long-ran ge sou nd
broadcasting technology of the MP Series digital voice broadcast
system in an extremely lightweight integration. It weighs only 270
grams, with an effective illumination distance of 150 meters and an
effective sound broadcasting distance of 300 meters, which can
meet the operational needs of law enforcement patrol and forest
search and rescue scenarios. By deeply integrating with DJI Pilot
APP, all functions of sound broadcasting and light illumination can
be called quickly, making the operation more convenient.
