MOBILE NVR WITH AI



Description

A Network Video Recorder (NVR) is a network‑based video recording system commonly used for surveillance and security applications. It receives and streams video footage from IP cameras and records the data in digital format onto a SATA hard drive. NVRs connect to IP cameras over wired or wireless networks, with video streams transmitted using standard network protocols such as TCP or UDP.


Features

  • Runs Linux Kernel 5.10 with a Yocto‑based Root File System (RFS).
  • Streams video from IP cameras over a wired network, configurable for up to 16 channels.
  • Uses Real‑Time Streaming Protocol (RTSP) based on a client–server architecture.
  • Supports H.264 and H.265 decoding with a Wayland sink for video rendering.
  • Simultaneously stores streamed video data on a SATA hard disk.
  • Utilizes open‑source GStreamer plugin pipelines to parse and decode RTSP packets.
  • Capable of rendering up to 16 video tiles within a single window, viewable via the HDMI interface.
  • Supports basic video analytics by running neural network models on the DEEPX NPU.
  • Supports the Qt framework for GUI application development.
  • Provides video scaling support.


Hardware and Connectivity:

  • MCU with OTP memory for storing the network MAC ID.
  • 6‑port USB smart hub, featuring:
  • Five USB 3.2 Gen 2 downstream ports
  • One USB 2.0 downstream port
  • Uses automotive‑grade connectors throughout the system.
  • Operating input voltage: 18–24 VDC
  • Battery: 14.8 V, 2000 mAh, up to 3 hours of operation
