Frustrating that I'm missing motion... video and settings included for review

[105437]

I'm trying to figure out why I might not be getting all of the motion in this event from my driveway captured. Any help would be appreciated.

Here is the first video alert. This clip stops while motion is still present.

Here is the second video alert. This clip misses the motion of the individual walking back to their vehicle and getting in.

Here are the clips as shown in BI


Here are my settings

Min. Object size, Min. Contrast and Min. Duration are way too high. I have my Min Object size around 230, Min Contrast around 12 and Min. Duration at 0.2 sec.

What smiti said, though I have my make times at about 0.6 or 0.7 and size/contrast vary by the cameras view. One important note is that if you are using direct to disk (which you probably are) its important to set your cameras iframe interval to match the fps. Blue iris will only start recording when a new frame is sent. It is also therefore important to set the pretrigger frames to a least double your fps.

@smiticans... I just changed it to 250, 15 and .7. We'll see how that works. @fenderman... here are my camera settings, do these look okay?


Thanks for the replies!

The settings look fine. I cant watch the youtube videos - it says private. It would help to see the videos.

Oops, try it now. Thanks

what are your pretrigger frame settings.

what are your pretrigger frame settings.

45

45

hmmm, see if the new changes you made help.

Yep, I'll see how it goes. 45 is okay I assume?

yes, but with your fps, I would set it to 40 or 60 since it should be a multiple of 20.

Good point, I'll go with 40. Thanks!

Dont be afraid to go 60, I doubt it will affect cpu performance and can only help you.

Done. Appreciate it.

After making the suggested changes, the rain overnight produced close to 200 alerts. Any kind of tuning that can be done to minimize that? Thanks

you will need to clone the cameras and have distinct settings for alerts vs recording. This is the only way to ensure you never miss true motion.

Thanks fenderman... how do I clone a camera? Besides that I'm not sure I'm grasping how that would help. I don't want to record everything 24/7. I only want to record alerts and I want those alerts meaningful. Capturing small animals or rain drops with alerts is counterproductive for me. I'm willing to try other things and I'm still learning BI. I really appreciate your willingness to help.

simply add another camera to blue iris. Disable recording..only setup for alerts - with a higher threshold. Then hide the camera so you dont have doubles on the screen. Disable alerts on the recording camera.
You will not be able to eliminate all false alerts AND capture every legitamate movement. Storage is cheap. Its better to capture more than less.
