Arlo Pro 4 3 second lookback interruption

[taboni]

I have 2 Arlo Pro 4 cameras both plugged in to take advantage of the 3 second lookback feature.  There is a noticeable hiccup/flash in the playback which I am assuming takes place when the camera sense the motion.  Is there any way to eliminate this?    Here is an example

In this case it looks like the camera engaged low-light color and then immediately changed it's mind.

• Are you also seeing the hiccup/flash during daylight hours?
• Is low-light color turned on in the video settings for the camera?

[taboni]

There is a very slight hesitation during daylight hours but not as pronounced as night time.    I have spotlight set to off, so no color, and night vision set to on

I'm not seeing a hesitation here.  I am seeing that the exposure is being changed at 4.649 seconds.  That setting is too dark (which is something Arlo should probably take a look at).  It then gradually brightens over the next few seconds.

In the original (nighttime) recording, the exposure also abruptly changes at 4.313 seconds (and it looks like Nightvision is being briefly turned off at that point). Nightvision turns back on again at 4.926 seconds. This is clearly wrong behavior if low-light color vision is not enabled.

I'm using a tool called AVIdemux, which lets me see the individual frames - here are a couple of screenshots from the nighttime recording.

Tagging @JamesC, to call his attention to this thread.

Thanks very much for your information.  

Video settings set to 0

Low light settings  Spotlight off, Night Vision on

If I turn Spotlight on, then I can see that  Color is set to Off, Brightness 75% but I normally leave the Spotlight setting to Off.

I am thinking there are some bugs here (suboptimal behaviors), which is why I tagged @JamesC

Hi @taboni

Thanks for reporting this, I'll have the team investigate this. Do you mind providing another link to the video recording when it displays the issue. It looks like I was just shy of the expiration date on the first link you provided. You can send Via PM If you want. 

Thanks!

Just for completeness, I saw the following behaviors that maybe should be looked at:

1. The camera is resetting the exposure when motion is detected.  The result in the daytime video sample is that the exposure becomes too dark at that point.  It then gradually shifts back to the exposure before motion was detected.  When foresight is active, the exposure is already correct, so the camera shouldn't change it when motion is detected.
2. The camera is also turning off nightvision when motion is detected - even though the spotlight is set to stay off.  Again, with foresight on, the camera should already be engaging/disengaging nightvision as appropriate when the lighting changes. So when foresight is active and the spotlight is turned off, the nightvision state shouldn't be changed.

(2) assumes that when the camera is powered that Nightvision will engage/disengage as appropriate - there's no easy way to tell if that's true or not, so maybe that should also be confirmed by the developers.

Maybe also provide the second daytime sample.

@ShayneS : I suggest getting this one also.

@StephenB

Already on it yesterday : )

[ShayneS]

The Arlo development team is currently investigating this issue. We will provide an update as soon as we have more information to share with the community.

[taboni]

Any update on this issue ?

[ShayneS]

When the camera is in the failed state, have you tried to disarm and rearm the camera?

[taboni]

Many times.  Disarm, Restart, have pulled battery, etc.  I am still seeing an interruption.  Here is an example from yesterday  on one of the cameras, but it affects both.    https://my.arlo.com/hmsweb/users/library/share/link/DECAF71DF14DD56C_202207

[ShayneS]

Thanks, I provided this info to the Dev team and I will provide an update as soon as possible. 

[Kantera]

I just installed 11 outdoor Pro 4 cameras that are connected to power cables and I have the same issue.

[ShayneS]

Hi @Kantera

Are you able to share & provide a sample of the issue you are experiencing. feel free to pm me if you like. 

[Kantera]

Hi @ShayneS 

I just sent you a sample of my recordings via pm.

[ShayneS]

@Kantera

Thank you 

[ShayneS]

Hi,

Is this issue still reproducible? 

Thanks

[taboni]

Seems to be a little better since last firmware update. I will check recent recordings though
