Blueskysea specialists seem to have found a golden mean: a low-bitrate parking mode, and the main feature is in a smooth transition to a low bitrate without interrupting the recording, and a similar smooth exit from this mode

Video Sample 1 original
Automatic switch from 4Mbps to 12Mbps (night)
A file with a duration of 1 min was saved to the EVENT folder after the start of the movement (transition from the parking mode - at 20:59:26).
Thus there is no need for buffering - all videos will be recorded

I do not see the advantages of this solution nor understand the effort in its development.

The consumption is the same as in the 12Mbps mode and on Monday, when I take the car back to work, I will not be able to recover an event that occurred on Saturday or even early Sunday. If I put a large card and leave it all the time recording in 12Mbps mode I will get the same results. Where is the improvement?

I think it would be more interesting if the solution to the 4Mbps parking mode was added automatically deleting all the recordings except for the one initiated immediately before or during an event when it occurs, that way if you could have a medium card to record for several days and would not have dozens of unnecessary recordings.

El consumo es el mismo que en el modo 12Mbps y el lunes, cuando vuelvo a tomar el automóvil para ir a trabajar, no podré recuperar un evento producido el sábado o incluso la madrugada del domingo. Si pongo una tarjeta grande y lo dejo todo el tiempo grabando en modo 12Mbps obtendré los mismos resultados ¿donde está la mejora?

Pienso que sería más interesante si a la solución de el modo de estacionamiento a 4Mbps se añadiera el borrado automáticamente de todas las grabaciones a excepción de la iniciada inmediatamente antes o durante un evento cuando este se produzca, de esa forma si podría tener una tarjeta mediana para grabar durante varios días y no tendría decenas de grabaciones innecesarias.

The parking mode at 4Mbps uses 1/3rd the card space, so you can fit 22 hours on a 64GB card, or nearly 4 days on a 256GB card, so yes, you can record the whole weekend and still have it all on Monday morning.

If the g-sensor detects an impact then that file will be locked, so that even after 1 week of recording, that file will still be safe in the event folder and easy to find.

Yes, low bitrate is to extend recording time. Power consumption will be nearly the same because the cam is still recording constantly, just not running the processor and card quite as hard. B1W is very gentle on power consumption now so low bitrate adds a lot more time than with other cams.

Forgive, but I still do not understand it.

With a 64GB card would there be saved an event that occurs 40 hours after starting the parking mode at 4Mbs or would it be lost due to lack of space?
------------------
Perdonar, pero sigo sin entenderlo.

¿Con una tarjeta de 64GB quedaría guardado un evento que se produzca 40 horas después de haber iniciado el modo aparcamiento a 4Mbs o se perdería por falta de espacio?

If it is saved in the Event folder, then yes. At 4Mbps you get almost 20 hours loop recording in the normal video folder, plus a further 8 hours or so of event recordings in a separate folder which will take much longer to over-write.

OK thank you very much. I had not understood it but now I'm going to like this option a lot.

Mean this that all files in normal driving (g-sensor triggered) are saved to event folder?
and all files while parked (g-sensor quiet) are saved to normal folder?

No, sorry. I was not very clear.

All driving (12Mbps) and parked (4Mbps) video is saved to the normal video folder. Any events triggered by the G-sensor during driving or parked mode are saved to the Event folder, so they are not over written by normal video.

Sorry, I'm confused.
During driving g-sensor is continously triggered, so ALL driving files will be saved to event folder. Right?

No. That only happens if the gsensor is bad or excessively sensitive or events occur continuously, very unlikely thing.
---------------------
No. Eso solo ocurre si el gsensor está mal o excesivamente sensible o se producen eventos continuamente cosa muy improbable.

No. You can set the sensitivity limit to High, Middle or Low.

I have mine set to Middle. Only big bumps or holes in the road trigger the sensor to save a video clip to the Event folder. I sometimes get one event recording in a day from regular driving.

IIRC, B1W loop overwrites the event folder but I believe it didn't on the first firmware, maybe @estore009 can confirm that it works this way. Parking events would still be saved even if there were many others in that folder if I'm right, but you'd need to save the one you need before overwriting occurred. I do know that 30% of the card space is reserved for saved files so a bit of math will tell you how soon you'd need to act to save any files of parking damage onto your PC.

G-sensor in mine is perfect on medium, but setting to low sensitivity would be worth looking into. Test by letting the cam go into parking mode, then give your car a horizontal shove from front or rear as well as from the side- something like what would happen if someone backed into it a little bit. That should set it off. This might not catch all forms of damage, but it will get the worst if that happens. Or you can get into the habit of switching the g-sensor on and off as needed when you leave or enter the car, and retain high sensitivity for best protection. G-sensor is not a perfect technology in dashcams of any kind and I don't see that changing.

I have not check on my sdcard yet but for me, in normal driving I keep on hearing "event triggered" voice. By logic, this would means the videos will be saved in event folder. Will need to check further on this.

BTW, how does the B1W device knows what I am driving? It would depend on the g-sensor, right? Which means g-sensor is triggered which means event is triggered, no?

Yes, the inclusion of recording in normal mode comes from the signal of the G-sensor. The current file that was recorded with a low bit rate is transferred to the EVENT folder and you hear a voice alert that the file is locked.
If you continue to move, then the following files will be recorded in the usual mode in the folder DCIM
An example of the record can be seen in post #21 above.
G-sensor is set to LOW by default

so a new file is recorded into EVENT folder each time you switch on the car and move it?

Yes, the transition from the parking mode is accompanied by this every time.
File duration is 1 minute (I also have a 1 minute loop recording cycle) and this action can occur anywhere in the file - at the beginning of the file, in the middle or near the end of the file.

So with this firmware, is no need for the 3 wire hardwire kit? We would just need a +5V and ground?

Thanks

I've been using just a USB powerbank.
