nakita camera blurry

I installed the recommended nakita front camera from Amazon (bullet style, not that it matters). The image had the "snow" (horizontal moving lines and fuzz) and is blurry. I changed the power from the add-a-fuse to direct battery, now the "snow" is gone. The image is still very blurry.

The amazon listing says I may need a 12v dc rectifier/filter. I have not read any posts of Tundras members needing this.

Things I did to troubleshoot:
-change + direct to battery (5 fuse)
-ground changed in engine bay, terminal ring to factory ground spot on fender
-checked yellow rca connector, no change to image, electrical tape wrapped just to be safe

Any help appreciated.
