| DVRs are automatic and never require user intervention. When it is time to look at recorded images, the DVR continues to record. Images are time and date stamped and are very easy to review.
DVRs using IP (Internet Protocol) technology allow authorized remote users to view, transmit two way audio, fully control the cameras and system itself over a local area network (LAN), a wide area network (WAN) or via the internet.
With such flexible access, the modern generation of CCTV cameras may be operated remotely from a control center or, in fact anywhere with internet access. Equally, high quality digital images may be streamed anywhere and captured at a convenient and secure location. But it isn't only the operating platform that has developed significantly; camera technology too allows far more functionality. |
