DAHUA NVR4104-P-EI is a 4-channel network video recorder designed for small and medium surveillance installations. It supports up to 3840×2160 resolution input, records at common resolutions including 720p/960p/1080p, accepts SATA HDDs with maximum storage up to 16 TB, and offers one RJ-45 Ethernet port with PoE support. The unit is a 1U rack-mountable, white recorder with low typical power consumption suitable for continuous operation.

Advantages

This NVR provides high-precision face recognition, perimeter protection to reduce false alarms, and SMD (Smart Motion Detection) to distinguish humans and vehicles from other motion. AI Search and Quick Pick features speed up investigation by allowing attribute- and event-based searches and quick selection of human/vehicle targets. The recorder supports ANPR and camera-based heat maps when paired with compatible Dahua AI cameras, and it is compatible with a range of third-party devices for flexible integration.

How to use

Install the NVR in a 1U rack space or on a shelf, connect compatible PoE cameras to the network or PoE switch, and insert a SATA HDD for local recording. Use the web interface or client software to add cameras, configure recording schedules, enable AI features such as face recognition, perimeter protection, SMD, ANPR and heat map functions (when supported by connected cameras), and set up user accounts and storage management. Monitor live view, perform searches using AI Search or Quick Pick, and export footage as needed.

Recommendations

For reliable AI functionality, pair the NVR with Dahua AI-capable cameras and keep firmware up to date. Allocate sufficient HDD capacity based on camera resolution and retention requirements, and configure motion or AI-triggered recording to reduce storage use and false alarms.
