Network cameras are starting to appear in large parking lots at airports and elsewhere because of their natural suitability for such places.
To give an example, even if the monitoring room is a long way from the parking lot, or there are multiple parking lots separate from each other, network cameras offer excellent remote monitoring so that monitoring office staff can watch all fixed-point cameras simultaneously.
The high-quality progressive images furthermore offer crisp and clear views of parking lots. If the security service uses an up-to-date megapixel camera, it can zoom in on a portion of a wide-angle image and still offer enough resolution to capture license numbers or even images of people through windshield glass.
This can provide useful evidence for police in the event of vehicle break-ins or theft.
