NVR of Intelligent Security Surveillance System Based on Forlinx RK3568 SoM

With the development of network technology, there is an increasing demand for storing video data over the network. As a result, surveillance systems that were previously centered around DVRs (Digital Video Recorders) have further evolved into NVR (Network Video Recorder) systems with network capabilities.

NVR, which stands for Network Video Recorder, is the storage and forwarding component of a network video surveillance system. It is primarily responsible for functions such as accessing, storing, forwarding, decoding, and previewing network audio and video signals.

In today's increasingly complex and widely applied surveillance scenarios, intelligence has become an inevitable trend in the development of video surveillance systems. Intelligent security monitoring is one such application of NVR intelligence. It utilizes advanced technologies and intelligent algorithms to enhance security, reduce monitoring workload, and provide real-time access, playing a crucial role in the field. They are suitable for various applications, ranging from home security to large-scale commercial and urban surveillance projects.

With the constant advancement of technology, intelligent security surveillance systems will continue to evolve and improve, offering advanced features and greater convenience.

Intelligent NVR can be utilized in security surveillance and, with algorithmic support, can achieve the following scenarios:

Face Recognition Alarm:
Comparative recognition of the target face can be performed through video or image streams.

Fire Incident Visualization and Early Warning:
Intelligent detection and identification of smoke and fire points, issuing early warnings before the fire spreads.

Intrusion Detection and Alarm:
The system can monitor an area and provide alerts for unauthorized intrusion by using object recognition and motion detection.

Parking Space Vehicle Recognition:
By using object recognition or license plate recognition, the system can detect and identify unauthorized or improperly parked vehicles (underground garages).

Requirements Cases:
A video surveillance system solution provider plans to launch a high-performance NVR (Network Video Recorder) device to meet the diverse monitoring needs of smart security applications. In the envisioned product positioning of this customer, this NVR can provide intelligent monitoring functions in various security surveillance scenarios, such as face recognition alarms, visualized fire hazard alerts, intrusion alarms, parking space vehicle recognition, etc.

Unlike traditional NVRs, the implementation of intelligent monitoring functions requires AI computing power on the NVR's main control unit. This is because it needs to be able to run intelligent monitoring algorithms locally while performing traditional functions such as access, storage, forwarding, and decoding.

NVR of Intelligent Security Surveillance System Based on Forlinx 3568 SoM

Based on the above reasons, Forlinx Embedded recommends the FET3568-C SoM to customers as an ideal iteration tool for security back-end NVR devices.
