Dahua NVR4104HS-EI 4-channel EI Series IP Recorder

Dahua WizSense EI Series IP Recorder 4-channel

• Capabilities • EI series recorder capabilities depend on whether AI is utilized. Camera-based AI and recorder-based AI. Recorder-based functions include face detection, human identification, perimeter protection, and Smart Motion Detection (SMD Plus). Camera-based functions additionally include people counting, crowd monitoring, ANPR (Automatic Number Plate Recognition), traffic jam detection, and heat map generation. The machine’s bandwidth for recording, live monitoring, and network is 80Mbps.
• Camera Inputs • Up to 4 cameras with resolution up to 16MP
• Face Detection • This is a two-level operation: finding faces, i.e., detection in a frame (FD), and identifying detected faces (FR), i.e., human recognition. Both operations can be performed by the recorder and the camera; cameras from the fifth series can detect, and from the seventh series can identify. The recorder’s AI can detect faces in one input (12 faces per second), while camera-side detection is supported for all 4 inputs. The face identification capability by the recorder is one channel at 12 faces per second for faces detected by itself, and 4 channels at 12 faces per second for faces detected by the camera. When identified by the camera, all 4 channels are supported. A maximum of 10 databases can be created with up to 20,000 face images. AI fixes age, gender, facial expression, and other conditions; birthdays, addresses, and other information can be added separately.
