The image from an IP camera will not degrade in quality when transported over long distances, or when converted between different formats.
An analog signal however, does drop in quality when transmitted over a distance and when converted. The digital signal remains true – you will always have the same quality. A single IP camera can also stream different parts of the image to different recipients at the same time, reducing the bandwidth and storage requirements.
Figure 5: Installing a single camera instead of several minimizes installation and maintenance costs. Streaming only selected areas reduces the bandwidth and storage requirements.
