Viewing CCTV Cameras from Multiple DVRs and Locations

CCTV Surveillance DVR

The iDVR-E and iDVR-RT16 series surveillance DVRs support the ability to centrally view CCTV cameras connected to separate DVRs using the EMS (enterprise management software) that is included. This software is extremely useful for business owners that need an enterprise surveillance system consisting of multiple locations. Users can also combine viewing security cameras at their home(s) with cameras at one or more business. Please note that the EMS software is designed for Windows based PCs. The iDVR has a Mac software client, but it is limited to connect to one DVR at a time.

UPDATE! View Security Camera DVRs at Multiple Location

2023 Update! CCTV Camera Pros now highly recommends Viewtron security camera DVRs and Viewtron IP camera NVRs. We no longer sell iDVR-E products that are documented below. Watch this video to see the how the Viewtron NVMS (network video management software) can be used to centrally view security cameras from multiple locations. The software can also connect directly to Viewtron network IP cameras. Custom views can be configured that consists of cameras from different locations.

The below diagram illustrates a network diagram of three iDVR-E16 CCTV DVRs on the same network being monitored by a laptop computer that is also on the same network as the DVRs using the EMS software. Although this diagram shows the DVRs and computer on the same network, the EMS software also works when some or all of the DVRs are on different networks / locations, and the PC is also at a remote location.
