What is Effective Pixels in CCTV Camera?

Effective pixels in a CCTV camera refer to the number of individual picture elements (pixels) on the camera's image sensor that are actively used to capture and reproduce the final image. These pixels are the ones that contribute to forming the actual image, and they are distinct from total pixels, which include all the pixels on the sensor, including those that might be unused or reserved for other purposes. Dahua IMOU IPC-D22P Dome Lite IP Camera utilizes its pixel count to determine its effective pixels and, consequently, its image quality. The camera's pixel count is provided as "1920 x 1080," which represents the number of pixels along the horizontal and vertical dimensions of the image sensor.

In this case:

  • Horizontal Pixels: 1920 pixels
  • Vertical Pixels: 1080 pixels

To calculate the effective pixels, you multiply the number of horizontal pixels by the number of vertical pixels:

  • Effective Pixels = Horizontal Pixels × Vertical Pixels
  • Effective Pixels = 1920 pixels × 1080 pixels
  • Effective Pixels = 2,073,600 pixels
