We refer to an 8 camera DVR system here for illustration purposes. The DVR system provides a choices of 4 or 8 windows for Live View (in real time).
The first screen shot shows the Live Views of Camera #1 to #4. Cameras used in DVR systems are analogue based (not IP based). The resolution of analogue cameras does not reach the level of Megapixel as provided by most IP cameras. The views are reasonably sharp in the sample.
The second screen shot shows the Playback of a selected camera (#1 as shown) at a specified time (2010/03/11 06:02:14 as shown). The user console is simple to use.
