Quick answer

Decide how much coverage you need, prioritise night video and heat resistance, and budget for a good memory card and a hardwire kit if you want parking mode.

Choose your coverage

  • Front only: cheapest and simplest
    – Front and rear: captures rear-end collisions
    – 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.
