The Complete Guide to VGA Cameras: Capturing Clear and Crisp Images

Introduction

VGA (Video Graphics Array) cameras are a widely used type of camera that capture images with a resolution of 640 x 480 pixels. They are often used in security cameras, webcams, and other low-cost applications. While VGA cameras are not as high-resolution as newer camera technologies, they still offer a number of advantages, including affordability, low power consumption, and small size.

Understanding VGA Camera Specifications

Resolution:

As mentioned above, VGA cameras capture images with a resolution of 640 x 480 pixels. This is lower than the resolution of most modern smartphones and digital cameras, but it is still sufficient for many applications.

Frame Rate:

The frame rate of a camera refers to the number of frames per second (FPS) that it can capture. VGA cameras typically have frame rates of 30 FPS, which is sufficient for most applications.

Field of View (FOV):

The FOV of a camera refers to the angle of view that it can capture. VGA cameras typically have FOVs of around 60 degrees, which is suitable for most applications.

Sensitivity:
