Camera lens selection principle and monitoring angle:
Surveillance camera lens selection of the parameter value is greater, the more narrow the look, and vice versa, the smaller the lens parameters, the smaller the wider.
For example, want to see 10 meters need 3.6-4MM camera lens, 20 meters need 6MM camera lens and 30 meters need 8MM camera lens.
40 meters need 12MM lens, 50 meters need 16MM lens ,
With the environment, all according to the actual selection.
Monitor camera select 1/3 lens for example monitoring angle:
Surveillance camera lens 2.1MM small lens - monitoring angle 150 degrees;
Surveillance camera lens 2.5MM small lens - monitoring angle 130 degrees;
Surveillance camera lens 2.8MM small lens - monitoring angle 115 degrees;
Surveillance camera lens 3.6MM small lens - monitoring angle 80-96 degrees;
Surveillance camera lens 4MM- monitoring angle 78-80 degrees;
The camera lens 6MM- monitoring perspective 53-60;
The camera lens 8MM- monitoring perspective 40-45;
The camera lens 12MM- monitoring perspective 23-30;
To monitor the camera monitoring 16MM- angle 15-17 degrees;
Illustrate the relationship between focal length and monitoring angle:
Surveillance camera lens 3.5-8MM-- monitoring angle 96-45 degrees;
Surveillance camera lens 6-15MM-- monitoring angle 53-23 degrees;
Surveillance camera lens 6-36MM-- monitoring angle 53-10 degrees;
Surveillance camera lens 8.5-51MM-- monitoring angle 57-10 degrees;
Surveillance camera lens 6-60MM-- monitoring angle 53-6 degrees;
(Each manufacturer's lens angle is not the same, there is a certain angle difference.)
