Hi,

Could you tell me if it's possible to create an event rule in Nx Witness with several possible attributes?

For example, I want to create a rule if a white or black vehicle is detected.

I've tried using a comma, semicolon, etc...

 

Could you tell me if this is possible ?

And if so, what's the correct syntax ?

 

Best regards

(Note: Those attribute rules work well when I use them one at a time).

  Try using [space] as the delimiter.

  Generally the rules engine matches on [any] full words.

  Hi Loïc TONON,

  As Andrew Sharrem (thanks!) mentioned, try using the space, no commas or semicolons, etc.

  Hi

  Thanks for your answers, but we already use space for the "and" condition.
  For example, with LPR cameras. to create bookmarks if a licence plate is detected in a specific direction only. ("License Plate.Number"=AB123CD Direction=Outgoing) and it's working well.

  So, space = AND

  How can we use OR ?

  ? = OR

  Hi Loïc TONON,

  Currently, there is no OR option, currently it requires two rules, one for each condition.
