FAQ
Do I need a rear camera?
Rear-end collisions are the most common crash type, so a front + rear system gives you much better coverage.
What is parking mode?
It records bumps or motion while you're parked. It usually needs a hardwire kit to draw power from the fuse box.
Why don't you list exact prices?
Amazon prices change daily. We show a relative price tier ($ to $$$$) within this category and link to Amazon for the current price.
