FAQs – CCTV FOV Calculator
What is FOV in CCTV?
FOV (Field of View) is the width and height of the area a camera can see. It’s determined by the lens focal length and sensor size.
How do I calculate CCTV field of view?
Use our calculator: Enter sensor width, focal length, and distance to get an instant FOV result.
What is the typical sensor size for CCTV?
Common sensor sizes:
- 1/4 inch ≈ 4.8 mm width
- 1/3 inch ≈ 6.4 mm width
- 1/2.5 inch ≈ 7.2 mm width
Which lens gives a wider FOV?
Shorter focal lengths, like 2.8mm, give a wider field of view. Longer lenses like 6mm or 12mm give a narrower view but better zoom.
What is the ideal FOV for home security?
It depends on the area you want to cover. For wide spaces, use a wider FOV (short lens). For specific points (gate, door), use a narrow FOV (long lens).
