Security Camera Lens Angle Of View Chart

The below list shows the horizontal angle of view that you can expect when your camera has a 1 2 7 image sensor.

Security camera lens angle of view chart.

The field of view of a security camera also called the viewing angle is the area that the camera can see. Method 2 compensates for lens extension when focusing closer than infinity. If you look at the picture of the circle you will see that the dark blue section could be stated as 43 6 degrees field of view or angle of view. The full circle is 360 degrees.

Our fixed cctv security camera lenses range from 2 8mm to 25mm. On a specification sheet you will see the field of view measured in degrees. Most 1 4 ccd cameras produce a significantly narrower field of view with the same focal length lens. This chart displays angles based on 1 3 image sensors.

Remember that focal length is stated for infinity and most lenses decrease in focal length as you focus closer. For example the wansview wireless pan tilt zoom security has a viewing angle of only 65 degrees. They are designed to be installed in a corner provide a 90 degree field of view and provide effective surveillance in a 30 x 30 foot area. Field of view also known as fov the values for field of view fov come up frequently enough at the forums that i thought a list might be helpful for quick reference.

The average viewing angle of most security cameras is between 45 115 degrees with indoor cameras coming in on the lower end of the range. For example if your hd security camera has a 1 2 7 image sensor and a 2 8mm lens it will yield a 114 field of view. Method 1 is a naive method that assumes that the angle of view for the format which is the angle of view at infinity focus does not change when the lens is focused closer. When theory meets practice.

Camera with a larger size lens produce the more narrow field of view and the shorter viewing distance. Choosing the correct lenses for your security cameras is an important aspect of designing an effective video surveillance system. Think of the field of view as the angle between the two horizontal edges of the camera image. Check out the following examples to see this principle at play.

On the contrary camera with a smaller size lens also known as a wide angle lens produce a wider field of view and longer viewing distance. This range is for a security camera in a fixed position and doesn t factor in the entire range of a camera that has pan tilt and zoom. In an effort to guide your decision we have created this handy cctv lens calculator and view simulator. Many of our customers require a standard fixed wide angle 3 6mm lens.

When we are talking about cctv field of view for security cameras we are looking for a linear field of view. Blink xt has a viewing angle of 130 degrees. Due to the physical nature of lens optics these numbers listed should be considered accurate within 3 and therefore a few feet meters as well. However this camera can view with pan 350 degrees.
