More than I can review. ;)
Here are some daytime videos of Z7 and G90.
G90 videos are more crisp and brighter.
G90's FOV is wider.

Z7 has great detail and quality is also very good but videos are soft compared to G90.
I'm sure if Z7 videos go through a video processer to enhance sharpness, it'll look close to G90.

Watch in 1080p...

Daytime videos:

Night time videos:
Z7: Has artifacts but brighter than G90 with 18mbps custom firmware.
G90: G90 has custom 18mbps firmware right now so night time is not as good as before.
I'll go back to factory version and add more night time videos later.
For now here it is with custom 18mbps firmware:
At 00:15, rabbit doesn't stop for me.

Edit: The youtube video shows much more details in dark area in G90 video compared to raw video in my PC. The screenshots below are what I see in RAW file.
So it could be just the firmware that set exposure at lower than 0 but still labels it at 0
.

Night screenshots:
G90 with 18mbps firmware: Dark areas are completely black with no details.
Garage door on the right is not even there. :eek:

Z7: Much brighter, more details in the dark areas.

G90 with 18mbps firmware: Dark areas are completely black with no details.
Where are the houses?
Z7 screenshot has the houses on both sides.
Almost ran over a rabbit today. :eek:

Z7: Much brighter, more details in the dark areas.
Houses are seen on both sides.

I know Z7 can't be better than G90 but this firmware did something.
Now G90 works good at good light but suffers badly at low light.
However, when there is enough light, G90 is better than Z7.
That should be the case at all light levels.
G90 with street lights: More clean/clear.

Z7: not clean.

But when light is very low, G90 becomes really dark:
G90:
No trees on the left at all... pitch black.

Z7:
Can see trees lining up in the left median.

G90: Right side is so dark, you can hardly make out there is a house there.
Pitch black on the left side, no curb is visible.

Z7: Very easy to see house. Left side curb is also visible.



I'll update once I go back to factory firmware on G90.

You really do a good job, comparing our Z7 and G90 in so detailed.
Who you contact with in our team? :)

Thanks.
I don't think I'm in touch with your team.

I got the Z7 and G90 from gearbest.com

Mounts of Z7 vs G90:
G90's mount is shorter than Z7.
Z7 is much smaller camera but the mount is so long it hangs much lower than the G90.
Since Z7 is smaller, a shorter mount can make it even more discrete.

Z7 is much easier to pan. I saw a hot air balloon on the road and it was so easy to turn the Z7 sideways.
G90 is stiff and much harder to turn sideways.

G90 suction cup is small and almost flat so doesn't hold for long but Vaseline helped quite a bit.
Z7 suction cup is pretty good, hasn't fallen off yet. In fact, I had to use pliers to pull it off as it was stuck like a glue.;)
