Dahua NVR4104HS-EI 4 channel EI series IP recorder

Dahua WizSense EI series IP recorder with 4 channels

• Performance – The performance of the EI series recorders depends on whether or not AI is used. Camera-based AI and storage-based AI. Recording-based features include face detection, human identification, perimeter surveillance and smart motion detection (SMD Plus). This is complemented by camera-based people counting, crowd tracking, car number detection, congestion detection and heat mapping. The machine has a bandwidth of 80Mbps for recording, live monitoring and over the network.
• Camera inputs – Up to 4 cameras with resolution up to 16MP
• Face detection – This is a two-step operation – finding faces, or detecting them from the frame (FD) and identifying the detected faces (FR), or recognising people. Both operations can be performed by the recorder and the camera, with cameras capable of detection from the fifth series and identification from the seventh series. Salvest’s AI is capable of detecting a face in one input (12 faces per second), with camera detection supported for all 4 inputs. The face identification capability of the recorder is one channel at 12 faces per second for faces detected by the recorder and 4 channels at 12 faces per second for faces detected by the camera. All 4 channels are supported when identified by the camera. Up to 10 databases with up to 20 000 face images can be created. Using AI, age, gender, facial expression, etc. are fixed, and birthdays, addresses and other information can be added separately.
• Number recognition – Not supported
• Perimeter surveillance – 2 channels with Salvest-based AI, up to 10 rules per channel, 4 channels with camera-based AI.
• SMD Plus – Intelligent motion detector for more accurate fixation of cars and people with recorder-based AI 4 channels, camera-based AI 4 channels
• Monitor output – 1 HDMI (4K), 1 VGA (FHD)
• Video compression – Smart H.265+/H.265/Smart H.264+/H.264/MJPEG
• Audio – 4 channels through cameras, plus 1 input, 1 output RCA (Two-way audio), compression G.711a; G.711u; PCM; G726
• Alarm – Notification-based
• Power supply – 12 VDC, 2 A, adaptor supplied
• HDD – 1 SATA port for hard disk drive installation
• Processing – 1U metal case with dimensions 260 mm × 232.7 mm × 47.6 mm and mass 0.8kg, operating temperature -10°C ~ +55°C.
• P2P – Dahua Cloud Connection is supported

The new AI generation EI series recorder is well suited as a central device for traditional video service solutions.
