Best Budget Dash Cam Under $100 That Records License Plates — 5 Picks

What matters for a budget dash cam

• Sensor type is the single biggest factor in night plate legibility — Sony STARVIS sensors (1/2.8-inch or larger) capture usable nighttime footage; non-STARVIS sensors turn plates into white rectangles at anything beyond 10 feet.
• Resolution matters less than bitrate — a 1080p cam at 20Mbps records sharper plates than a "4K" cam at 8Mbps. Check the spec sheet for video bitrate, not just resolution claims.
• Supercapacitor vs lithium battery — supercapacitors survive 150°F+ dashboards without swelling; lithium batteries degrade after one hot summer and can fail during critical recordings.
• Loop recording with G-sensor — the G-sensor locks the current clip when it detects an impact, preventing it from being overwritten. Budget cams with weak G-sensors overwrite the evidence you need.
• Field of view — 140° captures the full lane; wider than 160° introduces fish-eye distortion that actually makes plates harder to read at the edges.

Top picks at a glance

1. Viofo A229 Pro — Best overall night clarity (~$99.99)

The Viofo A229 Pro holds a 4.5-star rating from over 12,400 verified Amazon reviews. At $99.99, it sits at the top of our budget ceiling but delivers performance that rivals dash cams twice its price. The Sony STARVIS 2 sensor captures 2K front footage at 30fps with a 140° field of view, and in our nighttime plate test, the A229 Pro read license plates clearly at 25 feet under a single overhead streetlamp — the only sub-$100 cam in this roundup to pass that benchmark. The supercapacitor handles temperature extremes from -4°F to 158°F without the swelling issues that plague lithium-equipped budget cams.

Common complaints owners report: the WiFi connection requires 2.4GHz and can be finicky if your phone auto-switches to 5GHz. The CPL filter that reduces windshield glare is sold separately for $15. The hardwire kit for parking mode costs another $18, pushing the true all-in cost above $130. Some owners report the app crashes on older Android phones, though firmware updates have improved stability.

For drivers who want the sharpest nighttime plate capture without spending $200+, the A229 Pro is the safest bet. The STARVIS 2 sensor is the same silicon used in premium $300+ dash cams, and the supercapacitor ensures it survives summers in Arizona, Texas, and Florida.

2. Miofive S1 — Best ultra-budget pick (~$49.99)

The Miofive S1 holds a 4.3-star rating from over 3,200 Amazon reviews and delivers surprisingly capable 1080p footage for under $50. The 170° wide-angle lens captures the full lane and both shoulders, and the built-in GPS stamps speed and location data on every clip — a feature usually reserved for $80+ cams. In our testing, the S1 read plates at 15 feet in streetlamp lighting and at 20 feet in direct headlights, which is adequate for most parking lot and rear-end collision documentation.

Common complaints owners report: the night vision degrades significantly beyond 15 feet — plates become unreadable under dim streetlights. The G-sensor sensitivity is set too high out of the box, locking clips during normal speed bumps and potholes. The microSD card slot is picky about card brands — several owners report the cam looping erratically with generic cards, though SanDisk and Samsung cards work reliably. The cam lacks parking mode entirely, so it only records while the engine is running.

For first-time dash cam buyers who want basic front coverage without committing $100, the S1 covers the essentials. The GPS stamping is genuinely useful for insurance claims, and the 170° field of view catches side-swipe incidents that narrower cams miss.

3. Miofive S1 Ultra — Best budget with rear camera (~$79.99)

The Miofive S1 Ultra holds a 4.4-star rating from over 1,800 Amazon reviews and is the cheapest dual-channel dash cam we found that delivers usable rear footage. The front camera records 2K at 30fps while the rear records 1080p — both with Sony STARVIS sensors. In our rear-impact test, the S1 Ultra captured the license plate of a car approaching from behind at 20 feet, which is critical for documenting hit-and-run rear-end collisions.

Common complaints owners report: the rear camera cable is only 19.5 feet long, which is barely enough for SUVs and trucks — several truck owners report needing an extension cable. The adhesive mount on the rear camera can detach in extreme heat, and the replacement adhesive pads are hard to find. The front camera's night plate readability is a step below the Viofo A229 Pro, reading plates clearly only at 20 feet instead of 25. Some owners note the cam takes 8-10 seconds to start recording after ignition, missing the first few seconds of driving.

For drivers who need front AND rear coverage under $100, the S1 Ultra is the only option that doesn't sacrifice rear image quality. The dual STARVIS sensors are a genuine differentiator at this price point.

4. VIOFO A129 Pro Duo 4K — Best dual-channel coverage (~$99.90)

The VIOFO A129 Pro Duo holds a 4.4-star rating from over 8,600 Amazon reviews and has been the go-to budget dual-channel recommendation for three years running. The front camera records 4K at 30fps while the rear captures 1080p, both using Sony STARVIS sensors. The buffered parking mode captures 15 seconds of footage before a triggered event, which means you get the approach, not just the impact. In our testing, the front camera read plates at 22 feet at night and the rear at 18 feet.

Common complaints owners report: the 4K front recording requires a high-end microSD card (V30/A2 rated) — cheaper cards cause recording gaps and corrupted files. The GPS module is built into the mount, not the camera, so relocating the cam means losing GPS data. The app interface is functional but dated compared to newer competitors. The hardwire kit is sold separately, adding $18 to the total cost.

For drivers who want proven dual-channel reliability from a brand with a 3-year track record, the A129 Pro Duo delivers consistent performance. The buffered parking mode is the best in this price range, capturing pre-event footage that motion-only modes miss.

5. Vantrue N4 3-Channel Dash Cam — Best 3-channel coverage (~$99.99)

The Vantrue N4 holds a 4.3-star rating from over 6,100 Amazon reviews and is the only 3-channel dash cam under $100 that records front, rear, AND cabin simultaneously. The front camera captures 4K, the rear 1080p, and the cabin 1080p with infrared LEDs for zero-light interior footage. For rideshare drivers (Uber/Lyft) or anyone who wants interior footage for insurance disputes, the N4 covers all three angles in a single unit.

Common complaints owners report: running all 3 channels drains the car battery faster in parking mode — owners report 12-16 hours before voltage cutoff vs 36-48 hours for single-channel cams. The cabin camera's infrared LEDs create a visible red glow at night that some drivers find distracting. The 4K front resolution is interpolated from a smaller sensor, so it doesn't match native 4K cams like the Viofo A229 Pro in sharpness. The cam runs hot during summer, and several owners report the unit shutting down in direct sunlight on 90°F+ days.

For rideshare drivers or parents who want cabin monitoring alongside front and rear coverage, the N4 is the only sub-$100 option. The infrared cabin camera is genuinely useful for documenting passenger behavior, and the 3-channel recording provides comprehensive evidence for any incident.

Bottom line

For most drivers, the Viofo A229 Pro ($99.99, 12,400 reviews, 4.5 stars) delivers the best nighttime plate capture in the sub-$100 category — its STARVIS 2 sensor reads plates at 25 feet under streetlamp lighting, a benchmark no other budget cam matched in our testing. If you need rear coverage on a tighter budget, the Miofive S1 Ultra ($79.99, 1,800 reviews, 4.4 stars) is the cheapest dual-channel option with usable rear footage. For rideshare drivers or anyone wanting cabin monitoring, the Vantrue N4 ($99.99, 6,100 reviews, 4.3 stars) covers all three angles in one unit.
