    Blue Iris now honors the Windows preference to move the cursor to the default button
    (usually OK) on pop-up message dialogs.

    The code to create and alert images has been moved to its own thread—this makes the video
    capture thread more efficient and allows for alert image post-processing.
    Also, the trigger/alerts thread has been re-written to work most effectively with Sentry Smart Alerts.
    Sentry Smart Alert configuration has been moved to a new page “Artificial Intelligence” from
    the Trigger tab in camera settings. ALPR support using Plate Recognizer has been added to
    this page as well. Sentry works to filter false-alarms via person-detection. ALPR works by
    analyzing the alert image—if a license tag is found, the number is added to the database and
    visible on the alerts list.

    Hi Guys,

    Sorry for the newbie question with ALPR config. Just wanted to know what the format is for Cloud API with token in the textbox. Is it appended as a query string in this URL ?
    License Plate Recognition API - High accuracy ANPR ? Sorry just need an example entry. Thanks

    Sign up for the free trial from the Learn more button in BI and you'll be given the API token to paste into that box in BI - I tried it earlier and it works fine - for now it seems the license plate info is just added to the full Blue Iris GUI and not in UI3.

    Oh ok. I got thrown off by the radio button label "Cloud API with Token" . It actually was only asking for the registered users API Token. I put it in and it works. Looks like it appends the license plate to the clips attribute. Looks good.

    Is there anyway to adjust the timing of the Alert pic?
    The LPR screen grab works in one direction, but not the other - the vehicle plate is out of the frame.

    Interesting feature but is there a way to process the responses or do something based on the plate match? Just having it appear in the alert doesn't seem to add much value, or am I missing something?

    I'm also just now trying out the Plate Recognizer feature. I have the same problem where the motion that triggers the recording has the car coming into the frame but the plate isn't visible yet. Those are the images being sent via the API, which of course result in no plate being recognized. If I play the video, usually just a second later is when the plate appears in the frame, so it'd be nice if there were some type of adjustable offset for that feature. Like "alert +1 second" or something where you can tweak it as needed.

    I'll admit this is not a dedicated ALPR camera placement, but it does give me human readable plates during the day, and usually at night as well. If I setup a specific camera that was pointed more directly at incoming cars, maybe I'd have better luck? Or would it trigger when the car is still far away, but it would be clearer and better if I could adjust it so the image being sent off had the plate larger in the frame?

    What I may end up doing for now is turning on the rectangles for the motion alerts and see if I can tweak some things so the trigger doesn't happen until the car and plate are really, truly, visible. It's a start, I suppose.

    I honestly wasn't expecting this feature to show up and since I can generally look at the recording and get a plate number in many cases, I'm not missing too much if I can't get this quite right, but it sure sounds like a neat feature and I was happy to try it out.

    Zone crossing alerts should fix the timing.

    Testing out Plate Recognizer on on of my LPR cams (HFW5241E-Z12E).
    The camera is also using OpenALPR for LPR detection, should be an interesting experiment.
