How to choose the focal length of the car camera lens
Oct 26, 2022
How do different car camera focal lengths work? What's the difference?
In the case of the same pixel of the car camera:
The smaller the focal length, the closer the viewing distance and the larger the field of view.
The larger the focal length, the farther the viewing distance and the smaller the field of view.
In the same position, install car cameras with different focal lengths to get different picture effects:
How to choose the focal length of the car camera?
Different usage scenarios require different focal lengths.
Without considering pixels:
For scenes with a large field of view and a very small range of object distance changes, a lens with a focal length of 1.7mm-2.8mm can be used.
For scenes with a large field of view and a small range of object distance changes, a 3.6mm or 4mm focal length lens can be used.
For scenes with a small field of view and a wide range of object distance changes, a focal length of 6-12mm lens can be used.
In passenger cars and trucks, which is what we often say, the in-vehicle monitoring of the two-passenger and one-dangerous vehicle camera is generally longer and adopts a 3.6MM or 2.8MM focal length vehicle camera. A lens with a focal length of 6MM or larger, so that you can shoot at longer distances.
In general, the vehicle-mounted camera for monitoring in the general taxi network vehicle generally adopts a wider-angle vehicle-mounted camera, because the policy requires the camera to be able to photograph the driver and passengers in the passenger seat, and it is best to photograph the rear row. For passengers in position, our company has a camera that can meet this angle requirement.
