    Hello!

    I am a current ZoneMinder 1.30.X user who is looking to swap to Blue Iris due to ZMs slow update cycle and apparent assploding when installing a new HD cam on an otherwise beefy machine, but I digress.

    I am testing out my BI setup using the evaluation version and noticed that when a motion event occurs, the thumbnail (and SMS alert) will show the red box where motion was triggered, but when I playback the clip to review and enable the "Test through motion detection" option, no red box appears! This is fairly aggravating because it does not allow me to tweak motion detection settings properly to fine tune things for my needs...

    Any ideas of what's happening here?

    Thanks!

    "With D2D recording, this can only start on a key frame boundary. Ideally, the camera will send one 1 key frame per second. Please see what yours is sending ... look at status/cameras. The key frame rate is shown alongside the overall rate." - BlueIris Support reply I got a while back

    So, in your camera settings, set your key frame (sometimes just referred to as frame) rate to match your frames per second rate (also set in your cameras, ignore the setting in BlueIris, set that as high as it will allow)

    I happen to prefer to see a bit of what comes before the motion trigger, so I also set my cameras to buffer 3 seconds. I also record 30 seconds after. A little before before and after and nothing much gets missed.

    Right - I have the same setup in terms of before and after recording. I'll check the key frame but I do believe it is set the same. The issue is not that it is missing motion, it's that when I review the footage and put it through the motion detection test, it does not always show what actually triggered the motion (i.e. the red box).
