Dashcam video recording issue (blurred moving objects)

[MickY]

Would anyone know why my sentry recorded videos show blurred moving objects ? See images attached. This issues makes it impossible to see people's faces, etc.

This happens almost always and with any camera (front, side or back). Issue is fairly repeatable.

The issue does not happen on dashcam videos (while driving) which is strange. It only happens when car is parked and video is recorded as "sentry" video.

Here is also a video of the issue:

Any feedback is appreciated.

Sorry title says "dashcam" issue. It's sentry issue. I couldn't fix the title after posting

Haven’t seen that before. Try rebooting and see if that helps.

I see that so often. Has been the case since Sentry exists, at least on my car. Reboot doesn’t fix this. Don’t know why this is, but most of my footage has this. On all camera’s, so not only the front one.

I see. So it's not just me.

I have rebooted many times also. I have gotten many software updates since delivery.

I'll be making a service appointment. Just wanted to ask around first.

Sounds like the memory stick it’s writing to probably can’t keep up with the bitrate and drops some frames. Potentially doesn’t happen when driving because the car is in a lower power mode during sentry recordings? Just a guess.

Easy way to test the theory though, just try another memory stick.

I would be interested to hear back from you what the SC response was. My guess is nothing, since this is another béta function in the car and the USB device is ‘user related’. Nevertheless, I never bothered reaching out to the SC myself, so who knows, maybe they do have an answer that could help us all. . Thanks

These smearing artifacts are typical of the compressed video stream suffering from transmission drop-outs as it's being written to the USB stick. As lensovet suggested, trying a different USB device might produce better results. The problem might also be internal to the car if the data loss is happening on the network between the video encoder and the MCU.

This typically happens with slower drives. I bet if you use a faster flash drive or SSD, you won't see this nearly as often.

Have you had any luck with this? Mine is doing the same thing:

 

[lensovet]

Generally means your flash storage is unable to keep up. Make sure you have enough free space and invest in a better quality drive if it continues.

I'm using the Tesla USB drive that came with my car but I guess I'll try a different one.

@n2fooz I switched from the Tesla supplied USB stick to a microSD card rated for dash cam and USB adapter with good results.
