Ok, got the new camera and IT’S TOTALLY A HUGE CRAP SHIT. Spent hours to try to get focus but the truth is that these 11$ 1000TVL cameras are totally fake.
Swapped with a kingkong style, classic 600TVL camera, and uhaa crisp and clear image, real colors, real definition, real focus.
So, I warn you: do not purchase these 1000TVL camera from Banggood.
For reference, this is crap 1000TVL camera: https://www.banggood.com/1_2g-Super-Light-1000TVL-14-CMOS-2_8mm-Lens-FOV170-Degree-Mini-FPV-Camera-p-1110381.html?rmmds=myorder
You can recognize the crap camera from the electronics components on the back:
Also, the audio was very useless: totally disturbed and noisy, a total mess.
This is instead the good camera:
And audio is cristal clear.
