Dash cams have quickly moved from being luxury tech to essential car accessories. But if you’re shopping for one today, you’ll likely face the big question:
Should you buy a front and rear dash cam, or upgrade to a 3-channel dash cam?
Both options offer protection, but they’re built for different needs. In this guide, we’ll compare the two, break down their pros and cons, and help you decide which setup is best for your vehicle.
What Is a Front and Rear Dash Cam?
A front and rear dash cam records from two angles:
- Front camera: Captures the road ahead.
- Rear camera: Monitors what’s happening behind your vehicle.
This setup is ideal for drivers who want coverage for the most common accident scenarios: rear-end collisions and head-on crashes.
Best for: Daily drivers, commuters, rideshare drivers who don’t need in-cabin recording.
What Is a 3-Channel Dash Cam?
A 3-channel dash cam (also called a triple dash cam) adds a third camera to the front and rear setup:
- Front camera – Road ahead
- Rear camera – Road behind
- Interior camera – Records inside the cabin
The interior camera often comes with infrared night vision, making it perfect for rideshare drivers, taxi operators, or anyone concerned about passenger activity and theft.
Best for: Uber, Lyft, taxi drivers, families, and car owners who want 360-degree protection.
Front and Rear Dash Cam: Pros & Cons

- Easy installation with fewer cables
- Covers the most common accident scenarios

Disadvantages:

3-Channel Dash Cam: Pros & Cons
Advantages:
- Full protection: front, rear, and inside
