Details

The Dahua NVR4104HS-4KS3 is a representative of the new generation of Series 4 (S3) Lite NVRs. This 4-channel IP NVR is capable of recording video from IP cameras with up to 12 Mpix resolution. With a high input bitrate of 80 Mbps, it works perfectly with high-resolution cameras. 1 SATA port allows the connection of hard drives with a capacity of up to 20 TB. In the event of memory overflow, automatic overwriting is triggered to prevent loss of the latest data. Built-in USB ports allow you to plug in a pendrive or external drive and copy specific sections to external storage media.
The NVR is equipped with the SMD+ intelligent motion detection function, enabling precise filtering of objects such as people and vehicles. This function can be implemented directly on all channels by the NVR or supported by cameras equipped with this functionality.
The app for mobile devices and computers allows easy management from anywhere.

Key features:
  • recording at up to 12 Mpix (4000x3000 px) resolution
  • independent HDMI / VGA outputs
  • maximum input bandwidth - 80 Mbps
  • support for up to 8 IP cameras from Dahua or other manufacturers via Onvif
  • support for 1 SATA disk up to 20 TB
  • supported compression H.265 (Smart, +) / H.264 (+)
  • implementation: SMD+ (4 channels)
  • supported functions implemented by the camera: SMD+, perimeter protection with object classification (4 channels), face detection (4 channels), face recognition (4 channels), people counting, heat maps
  • 2 x USB 2.0
  • 100 Mbps Ethernet port
  • in/out audio for two-way communication

Key features:
Function ANR

The image from the IP camera is sent to the NVR as a data stream. In the event of a computer network failure (reduction of its bandwidth), the information is irretrievably lost, as the network does not buffer it and the camera cannot resend it. With ANR (Automatic Network Replenishment) enabled, the camera can save recordings to a memory card in the event of connectivity problems with the NVR. When the failure ceases, the recordings are automatically transferred to the recorder. In the event of an interruption in transmission, the operator does not need to take any action to have a complete recording on the recorder. To use it, you must also have a Dahua IP camera equipped with a memory card slot and a microSD card.
H.265 compression (+)
Compression is a very important parameter proving the device advancement. The better the compression, the lower the bandwidth requirement with the same subjective quality. H.265 (HEVC - High Efficiency Video Coding) is currently the most efficient compression method. Compared to its predecessor (H.264), it reduces the data stream and the demand for disk capacity by half. Therefore, hard drives with a halved capacity can be used, or recordings can be stored for twice as long. Its improved version H.265+ has been optimized for use in CCTV monitoring systems. They allow for further reduction of data streams.
