Vivotek LPR Camera Tested

By Derek Ward, Published Apr 15, 2020, 10:54am EDT

Vivotek has historically sold license plate capture cameras but not LPR. Now, they have released their own cameras with embedded LPR. How do they perform in real-world scenes?

IPVM Image

We bought and tested the IB9387-LPR 5MP V Series bullet to find out, testing recognition performance. Inside, we look at:

  • How accurate was capturing moving vehicles?
  • Did the camera miss license plates?
  • Did the camera recognize other objects as license plates?
  • What caused misreads?
  • How did the camera integrate to VMSes?
  • How did day and night H.265/H.264 bandwidth compare?
  • How did it compare to Hikvision's LPR camera?
