3G 4G WiFi GPS P5 Taxi Top LED Display with Light Sensor to Automatically Brightness Adjustment
Feature:
(1) Light weight panel design: The panel is only 18KG with led
modules installed;
(2) Shockproof: Taxi top led displays are always moving, as the
taxis are mobile vehicles;
(3) 3G or 4G, and WiFi wireless communication: You can connect the taxitops with your PC, smart phones, or Ipad;
(4) Both front and rear sides are IP65 protection level, all-weather proof, all humidity proof;
(5) TOP SMD LED has 140 degree wide viewing angle;
(6) 3,000~7,300nit brightness optional: we offer different selection for our clients, from 3000nits, 4000nits, 5000nits, 6000nits, and even 7300nits;
(7) Automatic brightness adjustment with light sensor;
(8) Powered directly through the vehicle’s 12V DC power system, and not need to add extra battery for it;
(9) Easy to mount onto taxi tops and convenient to remove it when necessary;
