[Doreen]

hello pinfi, tks for your kind attention!
the new excellent functions are available on A7AL50 and A7LA70 chipset only.

 

[Doreen]

G90 shape with A7LA50, A7LA70 samples are available now.

 

[Doreen]

HDR: High-Dynamic Range
F1.8 big aperture supports higher quality of video and supports low-light.

 

[Doreen]

[Doreen]

The IQ is still being improved, the most excellent video quality is to be continued. For whom have got samples, I'll provide updated firmware once have.

While I was waiting for super full HD video I found this one, showing how the LDWS, FCWS, FCMD, LLW functions may look like. The clip was added by BlackView (Dome).

@Doreen, is it gonna look the same in G90 A7LA50/70?

 

[Doreen]

hello pinfi, yup, the videos on YouKu were uploaded by DOME (BlackView is DOME's brand).
LDWS, FCWS, FCMD, LLW are the functions on A7LA50 and A7LA70 only.

sample you supplied is 30fps, looks ok but a 60fps sample would be nicer, perhaps something longer than 10 seconds would be good also

Hello every body as promised, I hereby upload the video of G90 A7LA70 Super Full HD 1920*1080p/60fps
https://www.sendspace.com/file/9xcurc

Kindly remind:
If the video does not run smoothly, it's beacuse the frame rate is so high -- 1080p/60fps.
Pls turn of other programs of your computer when playing the video, or do not use an very very old computer,
or change another player to review the video.

 

[jokiin]

at least you got the 60fps video this time

cleaning the window on the car would help a lot

 

[Doreen]

tks jokiin.
better and improved video will be provied soon.

LLW: Low Light Warning
When the sensor detects it is dark in front of the car, (G90) device will give driver a warning -- turn on the dipped headlight.
This function is also useful when car enters the tunnel.

LLW is already implemented in many cars to turn on headlights automatically when LL detected.

In dashcams it is another useless feature ( marketing trick ) which distructs driver ). In many cases you dont hear those "extra warnings" ( FCWD, LDWS, LLE etc ) due to them being not loud enough ( too small speaker ), example when you listen radio even 1/2 loud. And warning messages can not be seen on LCD due to dashcam mounted behind rearview mirror.
I see those "extrass" useless and in many cases distructive and danger to safe driving.

Better is to concentrate all efforts on main purpose of dashcam: video quality, stability and performance / functionality. Remove all useless "bling-bling, dong-dong" extrass and add supercaps, wifi, 24/7 parking mode etc.

 

[jokiin]

tks jokiin.
better and improved video will be provied soon.

do yourself a favor and provide at least a one minute segment, if you only put 10 seconds of video up people will just assume that you edited out the worst bit, file size is not an issue

 

[Doreen]

sure, I will. next time I upload the improved video I'll uplaod a complete segment.

 

[Doreen]
