Choose your coverage

  • Front only: cheapest and simplest

    – Three-channel: adds the cabin, useful for rideshare drivers

Video quality that matters

Resolution helps, but the sensor matters more at night. Look for modern image sensors and owner sample footage showing readable plates after dark.

Heat and power

Supercapacitors handle hot parked cars better than lithium batteries. For parking mode, plan on a hardwire kit or an OBD power cable, and set a low-voltage cutoff to protect your battery.

Memory cards

Buy a high-endurance microSD card built for constant writing, format it every month or two, and replace it about once a year with heavy use.

Mounting and the law

Mount behind the rearview mirror so it does not block your view. Windshield rules and audio consent laws vary by state, so check yours.

Frequently asked questions

Do dash cams drain the car battery?

Not while driving. Parking mode can, so use a hardwire kit with a low-voltage cutoff.

What resolution do I need?

1080p is fine for a front camera; 2K or 4K makes plates easier to read at a distance.

Can I install a dash cam myself?

Yes. Most people can tuck the cable along the headliner in under an hour. Hardwiring takes more care with the fuse box.

How to choose dash cams: the short version

Decide how much coverage you need, prioritize night video and heat resistance, and budget for a good memory card and a hardwire kit if you want parking mode. This dash cams buying guide explains the features that matter, the ones you can ignore, and which models we would buy or skip.

Our shortlist: the VIOFO A229 Pro 2CH Dash Cam ($280–$350) for best video front and rear. the Vantrue N4 Pro 3-Channel Dash Cam ($260–$330) for rideshare and families. the Garmin Dash Cam Mini 2 ($110–$130) for small and simple.

How much should you spend on dash cams? Budget models start around $110, while premium options reach $350. Spending more usually buys 4K front with STARVIS 2 sensors and front, cabin and rear cameras in one kit, but it is only worth it if you will use those features.

Front and rear coverage helps with rear-end collisions, the most common crash type. Supercapacitors cope with hot parked cars better than lithium batteries. Parking mode needs a hardwire kit or OBD power cable for full protection.

Yes, in every state, but windshield mounting rules vary. Mount behind the mirror and check your state’s rules on obstruction and audio recording consent. Most US insurers do not offer a discount, but footage can help prove fault after a crash.

Dash cams are popular Prime Day and Black Friday deals. Check your state’s windshield-mounting and audio recording rules, and buy a high-endurance microSD card at the same time.

Across the dash cams we cover, typical prices run from $110 to $350. Store prices change often, so treat these as typical ranges and check the current price before you buy.

The Nextbase 622GW Dash Cam typically costs $250–$330 and earns a Consider verdict. Buy it if you want built-in features like Emergency SOS crash alerts and image stabilization. Skip it if you want the best value; newer VIOFO models give sharper night video for similar money.

A few of the most-read verdicts on the site: Our top-rated choice among impact drivers is the Milwaukee M18 FUEL 2953-22 1/4", valued for four drive modes and top-class torque. Shoppers comparing pressure washers often start with the Sun Joe SPX3000 Electric Pressure Washer, which typically sells for $149–$189. Shoppers comparing leaf blowers often start with the EGO Power+ LB6504 650 CFM Cordless Leaf Blower, which typically sells for $249–$329. In portable power stations, the EcoFlow DELTA 3 Plus Portable Power Station ($699–$899) currently leads our picks for home backup and camping. Every pick links to stores in your country, and prices shown are typical US ranges for comparison rather than live quotes.
