The read
What's actually worth knowing.
- The front camera shoots in 4K while the rear shoots in 1080p, and the 12-inch screen is significantly larger than a standard mirror, which helps reduce blind spots.
- You can view live footage and playback recordings on your phone through the WiFi connection and included app, plus it has built-in GPS tracking.
- The 24-hour parking monitor requires a hardwire kit (sold separately) to work, so you'll need to buy and install that if you want continuous surveillance while parked.
As of Aug 15, the WOLFBOX G840S 12" 4K Mirror Dash Cam Backup Camera is overpriced at $139.99 — versus a $124.13 typical price and a $101.97 12-month low, based on Amazon's own price history.
Its price this year
This price is off the chart.
