Find the Perfect Lens. Calculate Coverage, Not Guesswork.
Use this tool to determine the **Field of View (FOV)** and **Pixel Density (PPM)** required for your specific needs, whether it's monitoring your HDB corridor or landed property driveway.
Smaller number = wider view. Larger number = more detail further away.
E.g., 2.5m for a standard HDB ceiling, 3.5m for a double-storey house exterior.
How far is the object (door, gate, car) you need to see clearly?
Horizontal Field of View (HFOV)
0.0°
The total angle the camera sees.
Coverage Width at Target Distance
0.0 m
The width of the area captured at your target.
Pixel Density (PPM)
0 PPM
Critical for evidence quality. (Pixels Per Meter).
