Trail Camera Coverage Calculator
Trying to figure out how many trail cameras you need for a property, or how much ground one camera actually watches? Enter your camera's detection angle and range along with your total land area to find out.
About this calculator
Calculate the ground area a trail camera covers based on its detection angle and range, and estimate how many cameras you need to cover a property.
Frequently Asked Questions
How is a trail camera's coverage area calculated?
It's treated as a circular sector (pie slice) defined by the camera's detection angle and maximum detection range, using the formula for the area of a circular sector.
Why include an overlap buffer?
Overlapping coverage helps ensure you don't miss activity at the edges of a camera's range and accounts for terrain, brush, or imperfect placement reducing effective range.
Does terrain affect these results?
Yes. This calculator assumes flat, open, unobstructed ground. Dense brush, hills, or obstacles will reduce actual effective range and coverage.
