Resolution

The resolution of an analog camera is calculated based on the number of horizontal scanning lines. The resolution of a network camera is calculated based on the pixels on the sensor (CCD/CMOS chip).

The approximate relationship between the two is as follows:

Analog Camera Network Camera
330 Horizontal TV lines = 512x492 pixels
330 Horizontal TV lines = 512x582 pixels
400 Horizontal TV lines = 640x480 pixels
470 Horizontal TV lines = 768x492 pixels
470 Horizontal TV lines = 768x582 pixels
800 Horizontal TV lines = 1280x960 pixels

When using a network camera's digital image, you can choose the image quality yourself. However, remember that the higher the image quality, the more data is involved. Images with more data will take longer to transmit and require more hard drive storage space.

Some basic principles regarding the amount of data in images:

  • Larger images require more data than smaller images.
  • Highly compressed images require less data than less compressed images, but the higher the compression ratio, the blurrier the image will be.
  • Scenes with more details generate more data than scenes with fewer details; for example, shooting a forest will produce a data-rich image, while shooting a plain wall will generate less data.
