Functions

4K Resolution
4K resolution represents a significant advancement in image processing technology. It provides four times the resolution of standard 1080p HDTV cameras, delivering superior picture quality and detailed images. This enhancement allows for clearer magnification of scenes, enabling the capture of crisp forensic video over large areas.

High Efficiency Video Coding (H.265)
The H.265 (ITU-T VCEG) video compression standard offers twice the data compression ratio at the same level of video quality, or significantly improved video quality at the same bit rate, compared to older compression technologies. It achieves this through advanced pattern comparison and difference-coding, enhanced motion vector prediction and motion region merging, and an additional filtering step called sample-adaptive offset filtering.

Intelligent Video System
When paired with IVS-enabled IP cameras, the NVR identifies and records video containing IVS data across all IP channels. It supports both standard and premium IVS features, detecting abandoned or missing objects, Tripwire violations, and intrusion violations. Additionally, it can record business analytics data such as Facial Detection, People Counting, and Heat Maps from IP cameras with built-in Intelligent Business Analytics.

ANR (Automatic Network Replenishment Technology)
NVRs equipped with ANR functionality automatically store video data on an IP camera's SD card when the network connection is lost. Once the network is restored, the NVR retrieves the stored video data from the camera seamlessly.

Easy4ip
The Easy4ip app, available on the iOS App Store and Google Play, simplifies surveillance. It allows remote access to NVR devices, live video viewing, event push notifications, and recorded video searches from an iPhone, iPad, or Android phone anytime and from virtually anywhere.
