NVR2104-S3 IP Recorder

Support for cameras with AI features

---

AI network recorders from the WZSSEnse series use the most advanced artificial intelligence technologies, including a deep learning algorithm directed mainly to vehicles and people, which ensures greater flexibility and accuracy for end users. In addition to ordinary registration, AI technology allows devices to distinguish objects and respond better to events.

P2P - Direct access to the recorder

---

The NVR recorder allows you to instantly establish a direct connection to the computer or with a mobile device (iOS or Android). The advantage of this solution is to obtain remote access not only to the device with a public IP address, but also to NVR located in a private network without the need for complex configurations.

Smart Add

---

Thanks to the Smart Add function, the installation of the IP system is as easy as analogue technology, regardless of whether NVR has a built -in PoE switch or not. The only requirement to remember that the NVR network recorder must be in the same network as the cameras.

Automatic Network Replenishment

---

This service guarantees the continuity of recordings in the event of a failure, disconnection or loss of the connection between the camera and the recorder. The system works on the principle of automatic detection of a network problem and a safe recording of recordings on the microSD card placed inside the camera. After the failure cessation, the recording is automatically synchronized and in the case of deficiencies the recorder will download the missing fragments directly from the camera.

Digital image enlargement

---

The function is used with the need to bring a given fragment of the displayed or played recording to obtain a more detailed preview. Through this function, strict supervision over priority areas in a given security zone is possible.

Privacy masks

---

Privacy zones are free -configurable image areas excluded from monitoring. Thanks to the private mask system, it is possible to record an image with respect for the right to privacy of third parties.

Perimeter protection

---

The main task of the perimeter protection function is to detect the intruder in the event of exceeding a specific line or entering the protected area. The Deep Learning recorder distinguishes objects violating the controlled area, e.g. a tree from a car or a man from an animal. In addition, the device sends an alarm when the undesirable event is detected.

Face detection

---

Facial detection allows you to automatically detect faces in digital images or video streams. For this purpose, AI Dahua recorder uses advanced deep learning algorithms, which previously processed a large number of data sources in the training process. This allows for effective and rapid analytics even in adverse conditions.

Face recognition

---

The face recognition function is used to determine whether faces are present in a given frame. Each face model is compared with the database saved and stored in the database for identification. In addition, the function can support vision systems on identifying important clients, working time control, access control, guests management and others.

Smart Motion Detection Plus (SMD+)

---

Thanks to the intelligent algorithm, Dahua Smart Motion Detection technology can determine and categorize the goals that trigger traffic detection and filter side objects. In this way, the amount of false alarms is reduced to a minimum.

Sharp and clear image

---

A camera to work in the IP system should be distinguished by the ability to accurately archive video material while maintaining a large amount of details and full smoothness of animation. The network camera guarantees undisturbed capture of monitoring recordings while maintaining a natural palette of colors and high fluidity of the image. Due to the fact that IP cameras are often used in changing observation conditions, the presented Dahua device is equipped with a number of technologies ensuring insensitivity and active adaptation of the camera to a heterogeneous monitoring environment.

IP67 tightness class

---

The high quality of the housing confirms the provision of the IP67 security class with the device.

3DNR - Noise reduction system

---

The noise reduction system allows you to maintain image transparency in a situation of variable signal strength level. In practice, this function protects the recordings against the occurrence of so -called The smoking effect and allows you to maintain detailed and crystal clear video recordings.

WDR - Extended dynamic range

---

The WDR function allows you to get a transparent and detailed image, thanks to the skilful leveling of both too bright and darkened fragments of the recording. Thanks to the WDR system, it is possible to maintain the readability of the entire monitoring in places with a varied lighting level of the observed scene.

BLC - Backlight compensation

---

The function allows you to eliminate the resulting effect when the camera is directed towards a strong light source, i.e. when the first plan becomes dark and not legible. Compensation consists in brightening the first plan, unfortunately also at the expense of the background, which also becomes brighter. Generally, the function improves image quality.

HLC - High light compensation

---

The algorithm detects image points that are strongly lit and then masks them enabling effective observation. HLC mode is extremely useful when observing underground parking lots. It allows you to read the license plates numbers that are covered with "bright stains" from the headlights.

Smart lighting function

---

The intelligent lighting function allows you to change basic image parameters, such as exhibition, contrast or brightness. The signal processor analyzes the image on an ongoing basis and immediately after detecting the x -ray reduces the power of the infrared illuminator. Thus, the image becomes more pronounced and the x -rays disappear.

RoI - Region of Interest

---

The Region of Interest system allows you to increase the quality of the recorded image in fragments of the observed scene indicated by the user. Thanks to the Roi function, economic recording of recordings and saving the total video files with the original image quality in priority areas is real.

Privacy masks

---

Using the characteristics of the camera with the function of privacy zones, it is real to adapt the method of functioning of the observation system to the spatial specificity and safety requirements of a specific installation site. Thanks to the privacy mask system, it is possible to freely determine the image fragments that will be excluded from the video supervision.

Powered by PoE technology

---

Power Over Ethernet is a solution developed with a view to carrying out quick and uncomplicated assembly of network devices and comfortable equipment operation and easy installation modernization. Thanks to PoE support in the 802.3af standard, connecting an IP camera will be real using the popular UTP computer pair. Saving the total number of cables necessary to start the device improves the monitoring system and allows the camera to be located away from traditional network power sources.

Support H.265 compression and Smart codec

---

The latest H.265 compression provides 40-50% savings in the field of bandwidth and memory. H265 coding uses advanced technology to improve the ratio between the size of the stream and the quality of the image. The H.265 compression format is only supported as part of one manufacturer.Smart codek H.265+ provides high image quality without charging the network. H.265+ coding has dynamic GOP, dynamic roi, flexible creation of frames and intelligent noise reduction. It provides saving of the bandwidth and disk space up to 70% compared to the H.265 standard.
