**FOV Calculator for Measuring Camera View Coverage**
FOV calculator helps determine how much area a camera can cover based on sensor size, lens focal length, and object distance. This tool is used in security, automation, imaging, and engineering to plan camera setups accurately and avoid frame coverage issues.

**What Does an FOV Calculator Do?**
A Field of View (FOV) calculator shows how wide or narrow the view of a camera will be. By using a few technical inputs, it allows users to estimate what a camera will capture at a given distance.

**Why It Matters**
Choosing the right lens and camera settings can be tricky. A field of view that is too small can miss important areas, while too large can reduce focus on key details. This tool helps avoid that by giving accurate measurements before the hardware is installed.

**Key Details You Need to Input**
To get results from the calculator, you need:

The sensor dimensions (width and height in millimeters)

The focal length of the lens

The distance from the camera to the object you are filming or photographing

These are used to compute the width, height, and diagonal of the camera's visible area.

**Where It Is Commonly Used**
FOV calculators are often used in:

Security Camera Planning: To make sure important areas are within view

Factory Automation: For tasks involving robotic vision or machine control

Aerial Cameras: To plan the coverage area for drones

Media Production: To frame subjects correctly in photo or video shoots

**Final Thoughts**
An FOV calculator gives you a clear idea of how much space your camera will cover. It helps save time, prevents planning mistakes, and supports better decisions when picking equipment or deciding on installation points.
