How to choose a dash camera
A dash camera earns its keep on the one day you did not expect. Everything below is about making sure it is still recording, still powered, and still readable when that day comes.
Parking mode is a wiring decision, not a feature
Every dash camera advertises parking mode. Almost none of them can sustain it out of the box, because parking mode needs the camera to run with the engine off, which means it is drawing from your car battery.
The correct installation uses a hardwire kit with a low-voltage cutoff, so the camera shuts down before it flattens the battery enough to stop you starting the car. Plug the camera into a cigarette lighter socket and parking mode either will not work or will end with a dead battery and a tow.
If you park on a street for long stretches, ask specifically about the cutoff threshold and set it with some margin, because batteries age and a threshold that was safe in year one can strand you in year three.
- Hardwire kit with a low-voltage cutoff is mandatory for parking mode
- Set the cutoff conservatively — batteries degrade
- Confirm whether the kit is in the box or an extra purchase
Heat, storage, and the card that fails first
A dashboard in summer is one of the harshest environments in a consumer device: sixty degrees Celsius or more behind glass, for hours. Cameras with internal batteries swell and fail in that heat; cameras built with capacitors tolerate it far better, which is why capacitor models are the usual recommendation for hot climates.
The storage card is the single most common point of failure, and it is almost never the card that shipped in the box. Continuous recording writes far more data than normal phone use, and a generic card will develop bad sectors within a season.
Use a high-endurance card rated for continuous recording, format it in the camera rather than on a computer, and expect to replace it every year or two as routine maintenance rather than as a repair.
- Prefer capacitors over internal batteries in hot climates
- High-endurance card, formatted in the camera
- Budget for a card replacement every one to two years
Field of view, mounting, and evidence
Wider is not better. A very wide lens curves the image and shrinks everything in it, so licence plates near the edge of frame become unreadable. A field of view around 140 degrees covers the lanes you care about without the fisheye distortion, and 150 to 160 is the practical ceiling before plate detail suffers.
Mount high and behind the mirror, where the camera does not block your view and the windshield wipers clear it. Note that windshield obstruction rules differ by state, and a camera mounted in your line of sight can earn a ticket regardless of how useful it is.
Finally, think about how the footage leaves the camera. If you cannot get the file off the card without the manufacturer's app, you have a video you cannot use. Locked event files that survive loop overwrite are the feature that matters at the moment of an incident.
- About 140 degrees is the sweet spot for readable plates
- Mount behind the mirror, clear of your sight line
- Check your state's windshield obstruction rule
Frequently asked questions
Does parking mode drain my car battery?+
It can, which is why it needs a hardwire kit with a low-voltage cutoff. The cutoff shuts the camera off before the battery drops too low to start the car. Without one, parking mode will eventually leave you stranded.
What size memory card does a dash cam need?+
High-endurance cards in the 64 to 256 GB range suit most people. Continuous recording writes far more data than normal use, so a generic card fails quickly. Format the card in the camera, not on a computer.
Can dash cam footage be used in an accident claim?+
Yes, and it is frequently the deciding evidence. Keep the locked event file rather than letting loop recording overwrite it, and export a copy promptly. Audio recordings carry consent rules that video does not.
Are wider dash cam lenses better?+
No. Beyond roughly 160 degrees the image distorts and distant detail such as licence plates becomes unreadable. Around 140 degrees covers the road ahead while keeping plate detail usable.
