Best Dash Cams Under $100

A dash cam is one of the cheapest ways to protect yourself after a crash, a hit-and-run or a dispute with an insurer. You do not need to spend much to get one that works: every pick here sells around or under the $100 mark at typical prices, though prices change often and some only dip below it during sales.

These picks are researched, not lab-tested. We compared manufacturer specs with independent reviews and owner reports to find cameras that balance video quality, heat tolerance and features for drivers in the US, UK, Canada and Australia.

The short version: buy the best sensor you can afford, choose a supercapacitor if you live somewhere hot, and budget for a hardwire kit if you want parking mode.

What you give up at this price

Spending around the $100 mark gets you solid daytime evidence, but some features stay out of reach. Knowing what is missing helps you decide whether a budget cam is enough or whether you should save for a mid-range model.

Rear-camera quality. Every front-and-rear kit in this price range uses a much cheaper sensor for the rear unit. Reviewers of both the 70mai A510 and Rove R2-4K Dual describe rear footage as noticeably softer, especially at night. It will show that a car hit you, but it may not show the plate.

Cloud and LTE features. Live remote viewing and instant alerts to your phone usually need an LTE module or a paid cloud plan, and those are rarely included at this level. The Garmin Dash Cam Mini 3, for example, needs a hardwiring kit, Wi-Fi and a Garmin Vault subscription for its parking alerts, and it costs well above this budget.

Long-term support. Bigger brands tend to release firmware updates for longer. DashCamTalk flags limited manufacturer support on some of the cheapest cams, so a well-known brand is worth a small premium.

True 4K. Real 4K sensors like Sony's IMX678 show up in models such as the Vantrue E1 Pro, which DashCamTalk tracks well above the $100 mark. Below that, a 4K label often means upscaled video.

For most commuters, these gaps do not matter. A clear front view with an accurate timestamp covers the large majority of insurance claims and disputes.

How to choose a dash cam under $100

Sensor quality matters more than resolution. A good sensor at 1440p often beats a weak one labeled 4K. Look for Sony STARVIS or STARVIS 2 sensors, which reviewers consistently rate well for low-light video. Be wary of budget cams marketed as 4K, since some upscale a lower-resolution image.

Front-only or front-and-rear. A single front camera covers most crashes and is cheaper and easier to install. A rear camera helps with rear-end collisions and tailgaters, but at this price the rear unit is usually much weaker than the front.

Supercapacitor or battery. Supercapacitors handle heat better and last longer in a hot car. Small batteries can degrade in high temperatures. If you live somewhere with hot summers, favor the Viofo or Rove.

Parking mode and hardwiring. Parking mode records bumps and break-ins while you are away, but nearly every camera needs a hardwire kit to do it. Buffered parking mode, like on the Viofo, is better because it saves footage from just before an event. Choose a kit with low-voltage cutoff to protect your car battery.

GPS. Built-in GPS adds speed, location and accurate time to your footage. That can help when proving where you were and how fast you were going. Some cameras put GPS in the mount, so check what is included.

Storage and high-endurance cards. Dash cams constantly overwrite data, which wears out ordinary memory cards. Buy a high-endurance microSD card designed for continuous recording, and check the camera's maximum supported size. The M500 avoids this question with built-in storage.

Legality of mounting. Dash cams are legal in the US, UK, Canada and Australia, but rules on windshield placement vary by state, province and country. Mount the camera behind the rearview mirror, outside your line of sight, and check local rules on recording audio.

Installing a dash cam

Most dash cams install in under 30 minutes with no tools. Clean the windshield, stick the mount behind the rearview mirror, and plug the camera into your 12V socket or USB port. Tuck the cable along the headliner and down the door pillar using the trim tool many kits include.

For a rear camera, route the cable along the headliner to the rear window. For parking mode, you will need to connect a hardwire kit to your fuse box. If you are not comfortable working with fuses, a car audio shop can do it quickly.

How we chose

We started with popular budget models from 70mai, Vantrue, Rove, Viofo, Redtiger, Garmin and others, then checked which are still sold and typically priced near the $100 mark in October 2026. We compared sensor, true resolution, rear-camera options, GPS, supercapacitor or battery, parking mode requirements, and app experience.

Specs come from manufacturer pages and retailer listings. Performance notes come from reviews by TechRadar, PCWorld, Digital Camera World, Vortex Radar and DashCamTalk, plus owner comments. We left out the Garmin Dash Cam Mini 3 because it lists well above this budget and lacks built-in GPS, and the Redtiger F7N because reviewers found its 4K mode is interpolated from a 2K sensor.
