Network Video Recorder(RZ/G2N)


Description

NVR (Network Video Recorder) is a video recording system over network, commonly used for surveillance and security purposes. This device streams security video footage from IP cameras and records the footage in digital format on to a sata hard drive. NVRs Uses wired or wireless network to connect to IP cameras. streams are transferred using TCP or UDP protocol.


Features

  • Renesas RZ/G2N Two 1.5-GHz ARM® Cortex®-A57 MP Core™ cores
  • Runs Linux Kernel 5.10 with Yocto Root File System (RFS)
  • Streams video from IP cameras over wired network that can be configured upto 16 channels 
  • Uses real time streaming protocol (RTSP) based on client server architecture
