RLC-410W stuttering

[stefan96aa_222876152590504]

I get this cam.
And i connect to app.
But, quality is bad, it stuttering, i choose max quality with 30fps, stutters very very bad.
I back to 1080p, the same result.
Advices?

Also, can someone explain cloud 7free days. I choose this, but when i go to select cam, i dont see my cam.
Also, what if cam records extend 1gb?
Thanks

I try this on pc and this works better on pc.
But, sound is late about 2 sec.
And on phone it show new image every two seconds and thats all.

During the night, to make sure there is enough light to light the image, the FPS would be reduced by force, if you turn on for 30fps, the image will smear, for the 7 days cloud which means it can only save 7 days video history, it will overwrite the former video with the day passing by, if there is any other concerns please feel free to contact:support@reolink.com, thank you!
