Understanding Ubiquiti Unifi G4 Pro Camera Field Of View And Coverage Area

by

The Ubiquiti Unifi G4 Pro Camera is a popular choice for surveillance due to its high-quality video and extensive coverage capabilities. Understanding its field of view (FOV) and coverage area is essential for optimal placement and security planning.

Key Features of the Ubiquiti Unifi G4 Pro Camera

The G4 Pro offers a 4K Ultra HD resolution, providing clear and detailed footage. It is equipped with a motorized varifocal lens, allowing users to adjust the focal length for customized coverage. The camera supports infrared night vision and has a wide-angle lens, making it suitable for various surveillance scenarios.

Understanding Field of View (FOV)

The FOV of the G4 Pro camera determines how much area the camera can see at once. It is primarily influenced by the lens’s focal length and sensor size. The camera’s adjustable lens allows for a horizontal FOV ranging from approximately 45° to 90°, depending on the focal length setting.

Horizontal, Vertical, and Diagonal FOV

The camera’s FOV can be described in three dimensions:

  • Horizontal FOV: The width of the area visible from left to right.
  • Vertical FOV: The height of the visible area from top to bottom.
  • Diagonal FOV: The longest measurement across the camera’s view.

Coverage Area Calculation

Calculating the coverage area involves understanding the camera’s FOV and the distance from the camera to the target area. The approximate coverage width at a given distance can be estimated using the FOV angle.

For example, at a 90° horizontal FOV, the coverage width at 10 meters is approximately:

Coverage Width ≈ 2 × (Distance) × tan(FOV/2)

Applying the formula:

Coverage Width ≈ 2 × 10m × tan(45°) ≈ 2 × 10m × 1 ≈ 20 meters

Practical Placement Tips

Proper placement of the G4 Pro camera ensures maximum coverage and security. Consider the following tips:

  • Position the camera at a height that minimizes blind spots.
  • Adjust the lens to cover the desired area without excessive overlap.
  • Avoid placing the camera facing direct sunlight or reflective surfaces.
  • Use the motorized zoom to fine-tune the field of view after installation.

Conclusion

Understanding the field of view and coverage area of the Ubiquiti Unifi G4 Pro Camera is crucial for effective surveillance. By considering the camera’s FOV specifications and carefully planning placement, users can optimize security coverage and ensure comprehensive monitoring of their property.
