The Dahua NVR4000-4KS2/L Lite Series introduces affordable yet powerful NVRs supporting 4K and H.265 encoding technology. Designed for applications requiring detailed image processing, it delivers 4K resolution capability and can serve as edge storage, central storage, or backup storage.
Its cost-effective and easy-to-install design makes it ideal for public safety, water conservancy, transportation, city centers, education, and financial institutions. It is compatible with numerous third-party devices, making it a flexible solution for surveillance systems independent of a VMS. With open architecture, it supports multi-user access and complies with ONVIF Profiles S, T, G, ensuring interoperability with IP cameras.
Key functions include:
- Perimeter Protection by Camera: Filters false alarms caused by animals, leaves, or lights.
- Face Detection by Camera: Deep learning algorithm for detection, tracking, optimization, and best snapshot output.
- SMD Plus by Camera: Categorizes motion targets and filters irrelevant alarms.
- People Counting by Camera: Tracks human targets to provide accurate entry/exit statistics and generates reports.
- Smart Codec: Scene-adaptive rate control for higher efficiency than H.265/H.264.
- DMSS App: Enables remote monitoring, live video, push notifications, and playback on iOS/Android devices.
