The Dahua NVR4000-4KS2 Lite Series is the first NVR in the Lite range to support 4K encoding and H.265 compression, delivering excellent performance at an affordable price. It provides 4K processing capability for applications requiring detailed images and can serve as edge storage, central storage, or backup storage, with an intuitive shortcut menu for easy management and remote control.
Thanks to its cost-effective design and simple installation, this NVR is ideal for a wide range of applications such as public security, water conservation, transportation, city centers, education, and financial institutions. It is compatible with many third-party devices, making it a flexible solution for surveillance systems independent of a VMS. With its open architecture, it supports multiple user access and complies with ONVIF 2.4, ensuring interoperability with IP cameras.
Key functions include:
- Perimeter Protection: Filters false alarms caused by animals, leaves, or strong lights.
- SMD Plus: Intelligent motion detection categorizes targets and filters irrelevant alarms.
- Heat Map: Displays crowd density and probability of people appearing.
- AI Search: Metadata search or facial image upload for comparison.
- ANR: Records video to IP camera SD card during network interruptions and transfers it back once restored.
- Smart Codec: Advanced bitrate control for superior encoding efficiency.
- DMSS App: Enables remote monitoring, real-time video viewing, push notifications, and playback on iOS/Android devices.
