Car Buyer’s Guide
A dash cam is cheap insurance — but only if the footage is actually usable. Prioritize resolution, reliable storage, and a parking mode, and skip the gimmicks.
Most dash-cam regret comes from blurry plates and cards that fill up. Here’s what actually matters.
1080p is the floor; 1440p (2K) reads license plates more reliably without huge files. 4K looks great but eats storage fast — only worth it if you want maximum detail.
| Front only | Front + rear | |
|---|---|---|
| Coverage | Ahead only | Rear-end & tailgaters too |
| Cost | $ | $$ |
| Best for | Basic protection | Rideshare, full coverage |
A front-and-rear setup captures the crashes you don’t cause. See our tested picks.
1440p (2K) is the sweet spot — it reads license plates reliably without the huge file sizes of 4K. 1080p is the acceptable minimum.
If you want to capture rear-end collisions and tailgaters — or you drive rideshare — yes. A front-only cam only protects against what’s ahead of you.
Not in normal driving. For parking mode, hardwire it with a kit that cuts off at a safe voltage so it won’t drain your battery overnight.
