Blackouts and network failures are the Achilles' heel for the IP video surveillance system. When these failures happen, the cameras will either be inoperative or will lose network connection. Lost video almost always equals "lost evidence" since no one knows for certain what could have happened on the spot at that time, which undermines the surveillance system's effectiveness. The uninterruptible power supply (UPS) may be in place for the cameras, NVRs, and network equipment, but is often too expensive to be a viable solution.
With edge recording support, the camera can record the video to its local storage (typically an SD or micro SD card) when its connection to the network fails. Once the connection is recovered, the video during the network downtime will be sent to the NVR to fill in the missing parts. Edge recording assures the availability of video, and is anticipated for mission-critical video surveillance needs, such as bank monitoring or crime suppression.
The Brickcom IP cameras with local storage are "edge recording-ready" when connected to the Digiever NVR. Edge recording is supported by Digiever's entire NVR line, including the DS-8200-RM Pro, DS-4200-RM Pro, DS-4200 Pro, DS-2100 Pro, DS-1100 Pro and DS-4000 and DS-2000 series.
