The Dahua NVR2104-P-I2 is a WizSense series network video recorder designed to deliver advanced AI functions and simplified management. It supports 1-channel face detection and recognition, 1-channel perimeter protection, and up to 4-channel SMD Plus (AI by NVR). It can manage up to 10 face databases with 5,000 images.
With AI by camera, it extends capabilities to face detection and recognition, perimeter protection, and SMD Plus across multiple channels. It offers a maximum decoding capacity of 6 × 1080p@30 fps, with adaptive decoding, and supports resolutions up to 12 MP.
Equipped with 4 integrated PoE ports, it simplifies IP camera installation. It is compatible with ONVIF (profiles T, S, G) protocols, ensuring broad interoperability. Its local and web GUI provide intuitive operation, while the DMSS app enables remote monitoring, notifications, and video playback on mobile devices.
