Hikvision NVR Load Tested

By: Ethan Ace, Published on Dec 14, 2017

IPVM members recently debated Hikvision NVR's performance under load in Hikvision 30+ Cameras On NVR - Apps And Client Really Slow Down And CPU Usage Jumps - Any Other Experiences Or Tests?

To see how Hikvision's NVRs and iVMS-4200 software handled heavy use, we tested a Hikvision DS-9632NI-I8 NVR, viewing 32 cameras using over 400 Mb/s bandwidth on multiple client PCs to see:

  • How does iVMS-4200 handle 32 cameras across multiple monitors?
  • How do settings such as resolution, frame rate, etc. impact this performance?
  • How much impact do CPU and memory have on iVMS performance?
  • How does the NVR stand up to heavy load? Are there issues with frame drop or lost recordings?
