Blackvue DR900S-1CH dashcam

With such a dashcam gone is the time when we could not catch or read something.
Even the lateral milestones on the highway are visible.
I guess we have a picture every 5 meters, even at high speed.
I surely need a polarizing filter for it. But even without that I find the pictures a bit too dark. This might be caused by the black spots on my car window above the rear mirror.

My first dashcam upload test had not appeared yet on the map after several days, so for my sunday expedition I used my Gopro Hero Black 7 as a backup. It had some problems with the SD-card, so I was happy to have the dashcam as a backup.

There are several gaps in the sequences. I did not investigate them all.

This gap is OK, The dashcam suddenly changed its location by several meters.

But this one is not. Mapillary has lost several meters which were on the dashcam.

But here my dashcam makes a translation of several tens of meters. I can say many bad things about my Hero7, but that has not happened with my action cam yet.

So should I continue wasting disk space with a backup action cam ?

I have also the Blackvue now. The first uploads took like 5 days to apear in my account. Have not maped that moutch yet. Some difficulty to sellect what to upload or not.

Today 20 of 157 files were refused because they contained no gpx data. I did not do any tunnel.

Starting the unit from cold needs GPS sync up time. I have found in some cases that a wait of 2-3 minutes is needed and if the vehicle is moving during the sync process it can take far longer. I have lost 10-15 minutes in the past when my initial route was in deep forest. Use the solid blue LED indicator to check lock status.

Starting the unit warm (eg warm day only being off for 30 minutes) takes far less time.

This BTW is why I don’t use video upload. I just leave the unit running all day then select only geo-referenced images after process only.

To check GPS is locked by viewing a video, the speed showing a number instead of —.

Yes, the problem was in the forest, even though the leafs are dry. That is really a shame for a supposed state of the art dashcam. It does not even show the correct side of the road.
I’ll make electrical contact as soon as I get in the car.

I won’t make a habit of it, but I uploaded a nightly video.
It shows the Scheldelaan in Antwerp, the chemical street.
The lights are nice to see, and it also gives night only information.
I am happy with the result.

I also was the first to mapillarize the Liefkenshoektunnel from North to South, the entrance and exit at least.

And I don’t know why, I don’t know how but I captured the Kennedytunnel.
