I have a 5241 and 5231 that I am testing for LPR's. The 5241 was bought from Andy on Amazon (the 4231 may have been as well).
Tripwire is not working on the 5241 and 5231 tripwire misses about half the cars that cross it.
I upgraded the firmware to the one listed here on the forum (R16) on the 5241 and the 5231 is on the latest I can find.

They are powered by a POE switch, have the tripwires setup up and the Smartplan is set to IVS on both camera.

Device TypeIPC-HFW5231E-Z12E

WEB VersionV3.2.1.825578
ONVIF Version16.12(V2.4.3.822559)
Security Baseline VersionV1.4

WEB VersionV3.2.1.900200

Any ideas?

Thanks.

Get OpenALPR if you are going to record license plates as it does not miss cars as long as they have a plate and the accuracy is pretty amazing. More than worth the $5 per month and all the time your are going to waste trying to get
tripwire working with cars, etc.

Try playing with the tripwire line length and target size. On a different Dahua camera I found sometimes the proportion of object to trip line size was a problem. Another time I had the minimum target size too big.

Ive had similar problems with both models and IVS.

I set regular old MD in addition to IVS at night only. I'm now getting 100%. Not fancy but it works fine.

Sometimes, in some situations intrusion works best.
I would read up on this in the LPR subject area. LPR | IP Cam Talk

Thanks for the options all.
I am tied to Synology SS, but have been testing a BlueIrs install with both of the AI options.

I'll keep testing.

I noticed that the old model of the IPC-HFW5241E-Z12E has this specification for the lux.

0.002 lux@F1.5 (Color, 30 IRE)
0 lux (Illuminator on)

Now the new S2 model has this specification for the lux.

  • 0.0007 lux @ F1.5 (Color, 30 IRE)
  • 0.0004 lux @ F1.5 (B/W, 30 IRE)
  • 0 lux (Illuminator on)
