There are basically two types of camera systems in construction projects:
- High-resolution photographic cameras with very large sensors taking detailed photos every few minutes
- Conventional surveillance cameras with small sensors and lower image quality, capturing images at close intervals or recording a moving image
Both webcam systems are acceptable, but they serve different goals:
Webcams with conventional sensors enable better protection against unauthorized entry and theft due to the denser image interval, but their low image quality does not produce an appealing look for presentation.
Webcams using a photo-quality sensor do not film constantly but rather photograph the desired vantage at intervals of a few minutes. The collected images can be used for detailed analysis and project discussion or for public relations and marketing.
