Overview
Choosing among dual dash cams is harder than it looks, because most listings promise 4K, night vision and parking protection while the details behind those words vary a lot. A front camera that records sharp footage means little if the rear camera is far weaker, or if parking mode needs extra hardware you have not budgeted for. This comparison looks at five front and rear models using three criteria: the resolution and sensor behind each camera, how easily you can connect and download clips by Wi-Fi, and what is really required to use parking and remote features. Use it to narrow the list before you buy.

The VIOFO A229 Plus gives 2K quality on both cameras, HDR and a supercapacitor, so the rear view is not an afterthought. It gives up 4K at the front, which some buyers will not accept.

The ROVE R2-4K Dual is a front and rear dash cam that pairs a 4K front camera built around a Sony STARVIS 2 sensor with a 1080p rear camera. It adds built-in GPS that embeds speed and location into clips, dual-band 2.4GHz and 5GHz Wi-Fi with an app for viewing and managing recordings, and a 128GB card in the box, so it suits drivers who want to start recording without buying extra storage. Its 24-hour parking mode, with timelapse, motion detection or collision detection options, needs a separate hardwire kit. One trade-off to check is that some retailer listings describe the front footage as 2.5K upscaled to 4K, while other pages list native 3840 by 2160, so confirm what the listing you buy from states. Do not confuse it with the pricier R2-4K Dual Pro, which is a different model with different sensors.
REDTIGER F7NP 4K Dash Cam Front Rear, STARVIS 2 Sensor, Free Card Included
The REDTIGER F7NP is a dual-channel dash cam with a native 4K front camera using a Sony STARVIS 2 IMX678 sensor, an F1.5 aperture and a 170 degree field of view. The rear camera records 1080p at 140 degrees. It has a 3.18 inch IPS screen, built-in GPS, loop recording, and 5.8GHz Wi-Fi with app control, with transfer speeds listed up to 20MB/s. That makes it a good fit for drivers who like to review clips on the device itself. Parking mode is offered, but listings note it needs a hardwire kit. The main trade-off is the 1080p rear camera, which is lower resolution than the 2K rear on some rivals. REDTIGER sells several similarly named models, such as the F7N, F7NA and F7N Pro, with different specs, and the card size varies by bundle, so match the exact model name and package before ordering.
VIOFO A229 Plus Dash Cam Front and Rear, 2K Dual STARVIS 2 Sensors & HDR
The VIOFO A229 Plus 2-channel model records 2K QHD from both the front and the rear, each using a Sony STARVIS 2 IMX675 sensor with HDR support. That balance is its main appeal: the rear camera is a step above the 1080p rear cameras found on many 4K rivals, which suits drivers who care about reading plates behind them. It uses a supercapacitor instead of a battery, which is generally preferred for coping with heat, and adds 5GHz Wi-Fi, GPS, voice control and a buffered parking mode. The trade-off is that the front camera is 2K rather than 4K, so it will not match true 4K for fine detail at distance. Published frame rate figures differ between sources, so check the listing before assuming 60fps on the front camera. A separate 3-channel version with a cabin camera and a waterproof-rear A229 Plus-W also exist, so pick the right variant.
70mai 4K Dash Cam Front and Rear, 4K+1080P Dual STARVIS 2 with 4G LTE, WiFi 6, GPS, 24H Parking
This 70mai dual-channel dash cam targets drivers who want remote features rather than only local recording. 70mai describes its 4K models as pairing a 4K front camera with a Sony STARVIS 2 IMX678 sensor and a 1080p rear camera, with HDR support. Its listing highlights 4G LTE remote access, AI motion detection, WiFi 6, GPS and 24-hour parking mode. The key caveat is that 70mai states the 4G functions need its separate 4G hardwire kit, which is sold separately and only available in select countries, and that kit is also tied to parking surveillance. Budget for that extra cost and check availability and carrier compatibility where you live before choosing it for remote alerts. Like several rivals here, the rear camera tops out at 1080p. Treat it as the choice for connected features, and as less compelling if you only want a simple standalone recorder.
REDTIGER 4K STARVIS 2 Dashcam Front Rear, 5GHz WiFi, Free 128GB Card
This is a different REDTIGER listing from the F7NP above, and the two should not be treated as interchangeable. Its title promises a 4K front and rear setup built around a STARVIS 2 sensor, 5GHz Wi-Fi and a free 128GB card, while the F7NP listing is titled around a 5.8GHz WiFi 6 link, a 3.18 inch screen and a card of unspecified size. REDTIGER sells a family of F7N-series models whose sensors, screens and rear cameras differ, and one independent reference notes that the original F7N used a different front sensor from the STARVIS 2 chip in newer versions. Because the title does not give the exact model code, check the sensor name, rear camera resolution and Wi-Fi version on the listing page before buying. It suits shoppers who want the card included and a 5GHz app connection, but it is not the pick if you need documented native 4K details up front.
Conclusion
Choose the ROVE R2-4K Dual over the others if you want a 4K front camera, GPS and dual-band Wi-Fi with a 128GB card already included. Pick the VIOFO instead if rear sharpness matters more, or the 70mai if remote 4G access is the goal. Read More →
Choose the REDTIGER F7NP if you want a documented native 4K front sensor and a built-in screen for checking clips without a phone. It beats the other REDTIGER listing on published detail, but the 1080p rear camera trails the VIOFO 2K rear. Read More →
Choose the VIOFO A229 Plus if you value equal 2K quality at both ends, HDR and a supercapacitor over headline 4K. It is the most balanced pick here, but skip it if you want the extra front detail that 4K cameras offer. Read More →
Choose the 70mai over the others only if 4G remote access, AI motion detection and WiFi 6 are worth buying its separate 4G hardwire kit. For a simple recorder with local Wi-Fi, the ROVE or REDTIGER F7NP offer more for less effort. Read More →
Choose this REDTIGER listing if the included 128GB card and 5GHz Wi-Fi appeal and you can confirm the exact model on the page. If you want clearly documented sensors, the F7NP, ROVE or VIOFO are easier to evaluate before you commit. Read More →
Frequently Asked Questions
Is 4K on the front camera better than 2K for a dash cam? +
4K records more pixels, which can help when zooming into distant plates or signs. A good 2K sensor with HDR can still be very usable, and many drivers prefer a 2K rear camera over a 4K front with a weaker rear. Match the resolution to what you need to read.
Do I need a hardwire kit for parking mode on a dual dash cam? +
Usually yes. The ROVE, the REDTIGER F7NP and the 70mai all list parking features that rely on a hardwire kit or, for 70mai 4G, a separate kit sold apart. Check whether the kit is in the box, because many bundles leave it out.
What is the difference between the two REDTIGER listings here? +
They are different models in the same F7N-style family. The F7NP listing names a STARVIS 2 IMX678 native 4K front sensor, 3.18 inch screen and 5.8GHz Wi-Fi, while the other listing gives fewer details. Compare sensor, rear resolution and Wi-Fi before buying.
Does a dash cam need a battery or a supercapacitor? +
Many modern dash cams use a supercapacitor, as the VIOFO A229 Plus does, because it is designed to handle temperature swings in a parked car better than a small battery. It stores only enough power to close files safely, so the cam relies on the car for power.
Is 4G LTE worth it on a dash cam? +
It only matters if you want live viewing, alerts or remote access away from home Wi-Fi. On the 70mai it requires a separate 4G hardwire kit sold apart, available only in select countries. If you just save footage locally, you can skip it.
