Do I need a rear facing dash cam?

Yes, a rear facing dash cam is highly recommended for most drivers. A rear cam captures footage of rear end collisions, which are the most common type of accident, and provides evidence for insurance claims and legal disputes. A front and rear setup, also called a dual channel setup, costs 50 to 100 dollars more than a front only setup and is the most popular configuration. A 3 channel setup with a cabin camera is also popular for rideshare drivers and for parents of teen drivers.

What is parking mode and do I need it?

Parking mode is a feature that allows the dash cam to record while the car is parked and the engine is off. The dash cam uses a motion sensor or a hardwiring kit to detect movement or impacts and records a short clip when triggered. Parking mode is highly recommended for anyone who parks on the street, in a parking garage, or in a high traffic area, since it captures hit and runs, vandalism, and break ins. Hardwiring the dash cam to the car battery is required for parking mode, and a battery discharge prevention device is also recommended to avoid draining the battery.

How much storage do I need for a dash cam?

A 64 GB microSD card is enough for most drivers, with enough room for 6 to 8 hours of 1080p footage or 3 to 4 hours of 4K footage. A 128 GB card is a better fit for 4K dash cams or for drivers who want to keep more footage on hand. A 256 GB card is the maximum supported by most dash cams. Loop recording, which overwrites the oldest footage when the card is full, means the dash cam is always recording. Important clips can be locked to prevent overwriting. Most dash cams support cards up to 256 GB, with high endurance cards from SanDisk, Samsung, and Lexar recommended.

How are dash cams installed?

Most dash cams are installed with a suction cup or an adhesive mount on the windshield, with the power cable tucked into the headliner and down the A pillar to the cigarette lighter or USB port. A basic installation takes 10 to 20 minutes. Hardwiring the dash cam to the car fuse box, which is required for parking mode, takes 30 to 60 minutes and is best done by a professional installer. Some dash cams, such as the Garmin Mini 2, plug into the OBD II port for power. The most discrete install uses a rear view mirror mounted dash cam or a dash cam that mounts behind the rear view mirror.

Second, reliable incident detection, with a G sensor that automatically saves footage when a collision or hard brake is detected. Third, a wide field of view, with 130 to 170 degrees being the sweet spot for capturing the road ahead and the side lanes. Fourth, a discreet design that does not block the driver's view.

How to Choose the Right Dash Cam

For a basic front only setup, the Viofo A129 Pro or the Garmin 67W are excellent choices. For a front and rear setup, the Viofo A129 Pro Duo is the best value. For a 3 channel setup for rideshare or for parents of teen drivers, the Vantrue N5 is the strongest. For a discreet setup, the Garmin Mini 2 is the smallest. For a smart setup with emergency SOS and what3words GPS, the Nextbase 622GW is the best. For a premium setup with cloud connectivity, the BlackVue DR750X is the strongest. The most important factor is the video quality, since a dash cam that cannot capture a license plate is not useful for evidence.

How to Install a Dash Cam

Most dash cams install in 10 to 20 minutes with a suction cup or adhesive mount on the windshield, with the power cable tucked into the headliner and down the A pillar to the cigarette lighter or USB port. Use a plastic trim tool to tuck the cable without damaging the headliner or the A pillar trim. Position the dash cam behind the rear view mirror to keep it out of the driver's view. The rear cam, if there is one, mounts on the rear windshield with a cable routed along the headliner and the C pillar to the front of the car. Hardwiring to the fuse box for parking mode is best done by a professional installer.

How to Store Dash Cam Footage

A 64 GB microSD card stores 6 to 8 hours of 1080p footage or 3 to 4 hours of 4K footage. A 128 GB card is a better fit for 4K dash cams or for drivers who want more footage on hand. A 256 GB card is the maximum supported by most dash cams. Loop recording overwrites the oldest footage when the card is full, which means the dash cam is always recording. Important clips are locked to prevent overwriting. A high endurance microSD card from SanDisk, Samsung, or Lexar is recommended, since regular cards wear out quickly under the constant write cycles of a dash cam. Replace the card every 1 to 2 years.

Are Dash Cams Worth the Money

Yes, dash cams are worth the money for most drivers. The average cost of a good dash cam is 100 to 300 dollars, and the average insurance deductible is 500 to 1,000 dollars. A single incident captured on a dash cam can pay for the camera many times over by proving the other driver was at fault. Dash cams also deter insurance fraud, capture unexpected events such as meteor strikes or police pursuits, and provide peace of mind for parents of teen drivers and for rideshare drivers. The honest answer is that every driver should have a dash cam, and the cost is low relative to the potential benefit.
