NVR4104-4KS2/L Rejestrator IP

Support for cameras with AI features

---

The modern DAHUA 4/L series recorder provides the user with the possibility of trouble -free operation of cameras equipped with artificial intelligence (AI) functions and business analysis functions. Appropriate configuration of the functions from the recorder level results in a constant analysis of the recorded image and allows you to quickly capture undesirable events. The function includes: perimeter protection, face detection, SMD+, counting people and a heat map.

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.

Built-in PoE switch

---

A feature that this recorder stands out is the use of a switch with PoE technology support. Power Over Ethernet technology allows you to provide power to the camera and allows you to send data packets from monitoring using one cable (standard UTP or FTP pair). This is a very useful and convenient solution that greatly facilitates the installation of cooperating products, reduces assembly time and allows easy synchronization of the entire system.

Video outputs

---

The recorder is equipped with a video output in the HDMI standard (1.4) with 3840 × 2160 (4K UHD) resolution and VGA analog output with Full HD resolution (1920 × 1080).

USB Ports

---

The recorder has 2 USB 2.0 ports (on the rear panel). They are used to connect external devices that increase functionality and facilitate daily system operation.

Onvif support

---

The DAHUA network recorder supports the standard of ONVIF communication used in network video protection installations. The support of a joint information exchange protocol guarantees trouble -free construction of monitoring structures based on devices produced by various manufacturers.
