modes for different installations and configurations.
4K resolution is a revolutionary breakthrough in image processing
technology. 4K delivers four times the resolution of Full HD 1080p
devices and offers superior picture quality and image details. 4K
resolution improves the clarity of a magnified scene to view or record
crisp forensic video from large areas.
Intelligent Video System (IVS) Recording
Working with IVS-enabled IP cameras, the NVR recognizes and records
video that contains IVS data on all IP channels. The NVR records standard
intelligence at-the-edge features, as well as premium IVS features that
detect abandoned or missing objects, Tripwire violations, and intrusion
violations. The NVR is also capable of recording business analysis data –
Facial Detection, People Counting, and Heat Map – from IP cameras with
built-in Intelligent Business Analytics.
The Heat Map option highlights the areas with the highest concentration
of people. This information can then be exported into a customized
report to assist in business or forensic analysis.
Automatic Network Replenishment (ANR) Technology
Network Video Recorders with the ANR function automatically store
video data on an IP camera SD card when the network is disconnected.
After recovery of the network, the NVR automatically retrieves the video
data stored on the camera.
The Smart Add function makes installing an IP surveillance system quick
and easy. The NVR automatically detects and lists IP cameras connected
to the same router as the NVR. This automatic detection makes adding
cameras to the NVR a seamless process.
