Details

The Dahua NVR2104-P-4KS3 is a 4-channel IP NVR that allows recording of up to 12 Mpix IP cameras. The high input bitrate of 80 Mbps allows it to work effectively with high resolution cameras. The NVR has a built-in 4-port switch PoE allowing direct connection and power supply to IP cameras. The video recorded by the device can be archived on a single hard drive with a capacity of up to 20 TB. In the event of a memory overflow, automatic overwriting is triggered to prevent loss of the latest data. Built-in USB ports allow users to plug in a memory stick or external drive and copy specific sections to external storage media.
The NVR is equipped with the SMD+ intelligent motion detection function for precise filtering of objects such as people and vehicles. This function can be implemented directly on 4 channels by the NVR or supported by cameras equipped with this functionality on 4 channels.
The app for mobile devices and computers allows easy management from anywhere.
Key features:
  • recording in up to 12 Mpix resolution
  • parallel HDMI (1080p) / VGA (1080p) outputs
  • maximum input/output bandwidth - 80 / 60 Mbps
  • support for up to 4 IP cameras from Dahua or other manufacturers via Onvif
  • SMD+ implementation on 4 channels
  • SMD+ and perimeter protection support on 4 channels
  • built-in 4-port switch PoE
  • support for 1 SATA disk up to 20 TB
  • H.265 (+) / H.264 (+) compression supported
  • ANR support
  • 2 x USB 2.0
  • In / Out audio for two-way communication
Key features:

PoE (Power over Ethernet) is the name of the IEEE standard for powering network devices via twisted-pair cable while transmitting data. It is possible to power devices such as cameras, telephones, switches, access points, etc. The guaranteed distance over which power transmission is carried out is 100 m. The two most popular standards are 802.03af, which guarantees a minimum power of 12.95 Watts for end devices, and 802.3at, which guarantees 25.5 Watts.

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.
