Choosing the right lens angle for your security camera depends on several factors, such as the desired field of view, the distance between the camera and the subject, and the camera’s image sensor size. A wider lens angle will capture a larger field of view, while a narrower lens angle will capture a smaller field of view but will appear to be zoomed in.
One way to determine the lens angle you need is to consider the area you want to capture and measure the distance between the camera and the subject. Then, use an online lens calculator to determine the lens angle that will provide the desired field of view. Additionally, you can experiment with different lens angles to find the best fit for your specific needs.
