pre-trigger type function for continuous recording?

[mjcother]

When I click on an alert on the right side of BI, the object, a bicycle in this case, is already halfway through the screen. How do I get the alert to point to a time earlier, either frames or seconds?


I am using direct to disk recording on 10Hikvision and 1 Huisun (specs below)

I can move the pre-trigger frames all around with no change, 50, 25, 100, etc... but I expect this since I am recording continuously
i-frames match the frame rate

I am recording continuously, so really all I want is when I click on the alert, for it to start displaying earlier... someone on a bike is already halfway through the screen... sure, I can manually scroll backwards, but that is a pain...

I did lower the 'MAKE TIME" (motion sensor min. duration) to 0.4sec and it helped some, but if I go too low, I pick up too many false alerts...

I am at 15% CPU on a i7 and using 1.15G Ram, recording to a single dedicate WD Purple 4TB drive, so performance is not an issue

This has been reported by others who record continuously. I would email support and ask for the change.

Thank you, I have sent the request off...

I have the same issue as Mike and am looking for an answer. In my case, I am reviewing alerts in Blue Iris IOS app on my iPhone and the object that triggered the alert is sometimes already out of the video when I play back the alert.

The OP's issue is specific to recording continuously. Otherwise the cause for your issue is setting related. Are you recording continuously?

 

[actran]

federman, yes, I am recording continuously (direct-to-disc, BVR format)

 

[fenderman]

federman, yes, I am recording continuously (direct-to-disc, BVR format)

Then you need to email support and ask for that function even when recording continuously.

FYI - the request i sent asked for that, and proposed using the existing 'pre-trigger' frames setting to just move the alert pointer for a minimum of programming effort...

 

[actran]

Great @mjcother . Thanks! Let us know if you happen to find out if it gets added to a release. This would improve usability of alerts.

I got this yesterday (sunday)... "[FONT=&quot]I see a way that this may be implemented in a straightforward way ... maybe I can get this into the update this week."[/FONT]

@mjcother @actran FYI, this is resolved in the latest update. https://www.ipcamtalk.com/showthread.php/12540-4-4-0-July-21-2016?p=113204#post113204
This is a great example, where folks who had an issue actually emailed support rather than complaining, then waiting for a fix without reporting it. 6 day turnaround from the request to solution. No other package vms package is that responsive.
