Security Camera Lens and Angle Comparison

Choosing the right lenses for your security surveillance cameras is one of the primary aspects of designing an effective video surveillance system. Each type of security camera lens features a different field of view.

Compare Security Camera Angles

The images below contain footage taken from a 2 MP camera. The vehicle is parked 70 feet from the camera. Cameras with higher megapixel count will produce a more detailed image.

Some cameras offer adjustable lenses in order to help capture the perfect angle. The digital zoom feature will allow you to see these images with more detail.

2.8 mm lens, 110° angle

1080p-2.jpg

This is the widest viewing angle you can achieve.

3.6 mm lens, 90° angle

1080p-3.jpg

This is the most popular and common lens size.

6 mm lens, 51° angle

1080p-6mm.jpg

This angle is not as wide as 2.8mm or 3.6mm, but you can see further in the distance.

12 mm lens, 29° angle

1080p-12mm.jpg

You can easily read a license plate from 70ft with the 12mm lens.

50 mm lens, 7° angle

1080p-50mm.jpg

You can view far away objects in close detail with a 50mm lens.
