Best answer: What is a good field of view for security cameras?

Wide angle cameras often have field of views between 60 and 110 degrees. More modern smart cameras tend to go beyond 110 degrees to provide a little more coverage. Cameras in this range are the best for smart security cameras, as they provide enough distance and width to cover an entire yard.

What is a 110 degree field of view?

Linear field of view = 2 (Tan (Angle of view/2) X Distance to Subject) Common Focal Lengths and Their Corresponding FOVs. 110 horizontal FoV is equal to 94 vertical FoV with a 4:3 aspect ratio and to 78 with a 16:9 one.

Is 80 degree viewing angle good?

Simply put, wide-angle IP cameras are more suitable to monitor objects of shorter distance. For example, IP cameras with 4mm focal length & 1/3″ CMOS sensor (80 degrees viewing angle) like RLC-420 are better to monitor areas within 26 feet radius.

What is the difference between 2.8 mm and 3.6 mm lens?

A 3.6mm lens is designed to provide an approximate 78° field of view and is the perfect camera in most CCTV applications. Most people think that a 3.6mm lens won’t show a large field of view, but as you can see from the below images, there’s not a huge difference between a 2.8mm and 3.6mm lens.

Are right angles 90 degrees?

A right angle is 90 degrees. An acute angle is an angle that is less than 90 degrees. An obtuse angle is an angle that is more than 90 degrees. These angles also help identify the different types of triangles.
