Do these covers work with my factory backup camera?

Yes. The camera hole is pre-cut into each cover, so your factory camera line of sight stays unobstructed. No drilling or enlarging needed.

What hardware do I need to install these?

Installation hardware is not included. You'll use fasteners from your OEM handles or acquire standard hardware suited to your door assembly — pick them up at any hardware store or use what you already have on hand.

Will the chrome finish hold up to weather and UV?

ABS chrome plating is designed for exterior exposure. It resists fading and corrosion in normal conditions, but inspect periodically for any finish wear in extreme climates.
