1 :  What is the angle for different lenses ?

1/3 chip angle can be customized with panoramic custom lenses = 180 degrees   2.1mm lenses = 140 degrees    2.8mm lenses=120 degrees   3.6mm lenses = 90 degrees  4mm lenses = 75 degrees
2: What are the waterproof levels ?  How to do waterproof technology ?

1. Camera blurry:
There may be foreign objects or dust on the glass of the camera   and the camera lens is faulty
2 .  Camera hair white
If the camera is too close to the car body at night    it may cause infrared reflection or large glass dust
During the day   if the camera turns white   it may malfunction or the power supply current may be too low   The total current cannot move the host and camera    or if the voltage is too low    the wire and copper wire may be too thin   resulting in less current passing through
3 :  Camera has no image
Voltage and current cannot move the host and camera
The camera cable is not connected correctly  
Short circuit and burning of camera caused during vehicle installation    In addition    the same vehicle may have a short circuit when installing other electronic products   or the short circuit of electronic products in the same vehicle may cause instantaneous high current and voltage and burn out
The host has not set a corresponding recording mode

4 cameras cannot see clearly at night
The infrared power of the camera is too small and the illumination distance is not enough
Too far away from the illuminated object
The infrared light is broken
Dust or obstacles on the camera glass
