A dual dash cam with loop recording keeps capturing the road without requiring you to clear the memory card after every drive. When storage fills, it overwrites older unlocked footage, while a G-sensor can protect certain clips after a collision. The best setup for you depends on video quality, whether you need GPS or parking mode, and whether a memory card is included.
These five options cover a range of needs, from a 4K front-and-rear system with GPS to more affordable-feeling setups with different camera layouts. Check the storage and parking-mode requirements before choosing: some models include a card, while others need one purchased separately.

Our Picks: Best Dual Dash Cams With Loop Recording reviews
1. Affver A4: Best Feature Mix for Front-and-Rear Coverage
The Affver A4 combines a 4K front camera with a 2.5K rear camera, giving both views more detail than a setup with a standard 1080P rear camera. Its wide-angle lenses are listed at 160 degrees in front and 155 degrees at the rear. That combination makes it a strong match for drivers who want clear coverage in both directions rather than prioritizing the front view alone.
Loop recording automatically replaces older footage as the card fills, while the G-sensor locks video when it detects a serious impact. The included 64GB card means you can start recording without buying storage separately. A 3.59-inch screen provides a direct way to check the camera and its settings, and built-in GPS records speed, route, and location information.
The A4 also offers WiFi 6 for transferring clips to a phone and a USB port in the car charger for another device. Keep in mind that high-resolution recording can use storage quickly, so check how much footage you need to retain and whether a larger supported card is appropriate for your use. As with any camera, locked clips may not be overwritten automatically, so you may need to manage protected files if storage becomes tight.
Pros:
- 4K front and 2.5K rear recording
- 64GB memory card included
- Built-in GPS and WiFi 6
- Large 3.59-inch IPS screen
Cons:
- High-resolution footage can fill the included card faster than lower-resolution recording
- More features may mean more setup than a basic dash cam
Verdict: Choose the Affver A4 if you want higher-resolution front-and-rear video, GPS, and a memory card in the box.
2. GKU D600 Pro Max: Best for GPS and Fast Clip Transfers
The GKU D600 Pro Max records 4K video at the front and 1080P at the rear. Its listed viewing angles are 170 degrees in front and 150 degrees behind. A STARVIS 2 sensor, WDR, and night-vision features are intended to help capture useful footage in low light, though lighting, windshield condition, and camera placement can all affect the result.
Loop recording replaces the oldest unlocked files when the card is full. A built-in G-sensor can lock a clip after a collision or sudden vibration, and there is also a button for manual locking. The camera includes GPS for recording route, speed, and location data. Its dual-band WiFi 6 connection is designed for viewing and transferring clips through the app without removing the card.
The key extra cost to plan for is storage: a memory card is not included, and the camera supports cards up to 512GB according to the product details. Parking monitoring also requires a separately sold hardwire kit. HDR is not available during dual-camera recording, so drivers choosing this model should not assume the front camera has the same HDR behavior in every recording mode.
Pros:
- 4K front recording with a 1080P rear camera
- STARVIS 2 sensor and low-light features
- Built-in GPS and dual-band WiFi 6
- Supports a memory card up to 512GB
Cons:
- Memory card is sold separately
- Parking mode requires a separate hardwire kit
Verdict: The GKU is a good fit if GPS and quick app access matter more to you than having a card included.
3. GMAIPOP 4K Dual Dash Cam: Flexible Rear or Cabin Recording
This GMAIPOP system records 4K video from the front camera and 1080P from the second camera. The second camera can be mounted to view through the rear window or positioned to record the cabin, making the layout useful for drivers who need to monitor passengers as well as traffic behind the vehicle. The product lists wide viewing angles of 170 degrees in front and 160 degrees for the second camera.
Loop recording overwrites older footage when the TF card is full, while the G-sensor can lock a clip after a bump. It also offers app control for viewing, downloading, and adjusting settings. One practical limitation is that WiFi is for connecting to the phone, not for powering the cameras or connecting the rear unit: the system needs a power cable, and the second camera connects by wire.
The product information describes time-lapse parking recording, but it requires a suitable power setup. The camera’s WiFi also needs to be turned on when you want to connect for downloads or app settings. That is a useful design choice for occasional transfers, but it is less convenient if you expect the phone connection to remain active all the time.
Pros:
- 4K front and 1080P second-camera recording
- Second camera can face the rear window or cabin
- Loop recording and G-sensor clip locking
- App access for video playback and downloads
Cons:
- Wired power and a wired connection to the second camera are required
- WiFi must be turned on to use the phone connection
Verdict: Pick this model if you want the option to record the cabin instead of the road behind you and do not mind running cables.
4. Meiqils 4K+2K Dual Dash Cam: A Flexible Rear-Camera Setup
The Meiqils dual dash cam is advertised as a 4K front and 2K rear system, with a 170-degree front view and 150-degree rear view. Its 3-inch screen lets you check footage and settings in the car. The rear camera is described as adjustable, which can help with aiming it at the road behind you or adapting the installation to a car, SUV, Jeep, or truck.
Loop recording starts when the camera is powered on and replaces the earliest footage as storage fills. A G-sensor can trigger an emergency recording and move protected footage out of the regular loop, so important clips are less likely to be overwritten. A 64GB card is included, and the product information lists support for cards up to 256GB.
The listing’s feature text contains an inconsistent resolution description, so check the product details and selected recording mode before purchase if 2K rear footage is a deciding factor. It also includes WiFi and an app for clip access, but the available details do not specify built-in GPS. Do not choose this model on the assumption that GPS route or speed data is included.
Pros:
- Advertised 4K front and 2K rear recording
- 64GB card included, with support listed up to 256GB
- Adjustable rear camera and 3-inch screen
- Loop recording with G-sensor emergency locking
Cons:
- Product details give conflicting resolution wording
- GPS is not listed among the supplied features
Verdict: Consider the Meiqils if an included card and adjustable rear camera appeal to you, but confirm the rear resolution before ordering.
5. Navycrest Q7: Compact 4K Front and Rear Coverage
The Navycrest Q7 records 4K video from the front and 1080P from the rear in dual-camera mode. It uses a Sony IMX sensor, a six-glass lens, and WDR features, which are intended to help balance footage in changing light. Its compact design may suit drivers who want a less prominent camera on the windshield.
Loop recording overwrites older footage when the memory card reaches capacity. A gravity sensor can help preserve clips when it detects an impact. Built-in WiFi connects the camera to a phone app for live viewing, settings, and downloads. The supplied product information does not list GPS, so this is not the best match if you want recorded route or speed data.
A memory card is not included, so add a compatible card to your setup before relying on the camera to record. Parking monitoring is available with a separately purchased hardwire kit; the product details describe collision-triggered and time-lapse options. If you want parking protection, factor in the extra installation and accessory requirements.
Pros:
- 4K front and 1080P rear recording
- Compact design and built-in WiFi
- Loop recording with gravity-sensor protection
- Parking-mode options with a separate hardwire kit
Cons:
- Memory card is sold separately
- Parking mode requires a separately purchased hardwire kit
Verdict: The Navycrest Q7 is worth considering if you want a compact dual-camera system and are prepared to buy storage and any parking-mode accessories separately.
How to Choose a Dual Dash Cam With Loop Recording
Match the camera resolution to your priorities
Higher resolution can capture more detail, but it also creates larger files. Compare both channels, not just the front camera: a 4K front camera paired with a 1080P rear camera does not provide the same rear detail as a system with higher rear resolution. If you often need to check footage from behind your vehicle, pay close attention to that second-camera specification.
Understand how loop recording handles important clips
Loop recording is designed to keep the camera running as the card fills by replacing older files. G-sensors and manual lock controls can protect selected clips from being overwritten, but protected footage can take up storage space. Check how the camera handles locked files and get in the habit of saving important footage somewhere else before the card becomes full.
Check the memory card requirements
Some of these cameras include a card; others do not. Confirm the type and supported capacity before buying a separate card, and consider how much recording time you need between transfers or card checks. More resolution and more active camera channels generally mean more footage to store, so a small card may require more frequent file management.
Decide whether you need GPS
GPS can add route, speed, and location information to recorded footage. It is useful if those details matter to you when reviewing a trip or documenting an incident. GPS is listed for the Affver A4 and GKU D600 Pro Max, but it is not specified in the supplied details for the other models here. Check the feature list carefully rather than assuming every WiFi dash cam includes GPS.
Plan for parking mode before installation
Parking monitoring may need a hardwire kit to power the camera when the vehicle is off. The GKU and Navycrest models require a separately sold kit for their described parking features, and the GMAIPOP product information also describes a power-dependent parking mode. Confirm the kit requirements and installation steps for your chosen model. A standard in-car power connection may not provide the same parked-vehicle monitoring.
Consider camera placement and wiring
A front-and-rear system needs a cable between the cameras, so think about the route from the windshield to the rear window before installation. If you want cabin footage instead of rear-road footage, the GMAIPOP offers a second-camera placement choice. Check the camera angles and mounting options to make sure the view suits your vehicle and does not obstruct your view of the road.
Compare app access with on-device controls
WiFi and an app can make it easier to view or download a clip without removing the card. A screen and physical controls can be helpful when you want to check settings directly on the camera. Think about how you are most likely to retrieve footage, and check whether the camera requires you to turn on WiFi manually before connecting.
Frequently Asked Questions
What does loop recording do on a dash cam?
Loop recording saves video in segments and, when the memory card fills, replaces older recordings to make room for new footage. This lets the camera continue recording without you having to clear the card after every drive.
Can loop recording erase footage from an accident?
Many dash cams use a G-sensor to lock a clip when they detect an impact, and some also provide a manual lock control. Locked clips are generally kept out of the normal overwrite cycle, but you should save important footage to another device as soon as you can. Check the camera’s instructions to learn how protected files are managed.
Do dual dash cams record the cabin?
Not always. Many dual-camera systems use one camera for the road ahead and another for the road behind. The GMAIPOP model described here lets you place its second camera to view either through the rear window or inside the cabin.
Do I need GPS in a dash cam?
GPS is optional. It can add location, route, and speed information to footage, but it is not required for basic video recording. Choose a model that lists GPS if you want those details stored with your trips.
Do all of these dash cams include a memory card?
No. The Affver A4 and Meiqils model list a 64GB card in the package. The GKU and Navycrest models say the card is sold separately. Check the listing for the GMAIPOP and for any card you plan to buy to confirm compatibility.
Will a dash cam record while my car is parked?
Some models offer parking monitoring, but it may require a hardwire kit or another suitable power setup. Check the specific model’s requirements before buying, and do not assume that a dash cam will keep recording after the vehicle is turned off when it is connected only to a standard power outlet.
Which dual dash cam is the best choice for most drivers?
The Affver A4 is a strong all-around option in this group because it combines 4K front and 2.5K rear recording with GPS, WiFi 6, and an included memory card. If you want a cabin-facing camera, consider the GMAIPOP instead; if fast app transfers and GPS are priorities, compare the GKU’s features and account for its separately purchased card.
Final Recommendation
For a well-rounded setup with higher-resolution footage from both directions, the Affver A4 stands out because it includes a 64GB card, GPS, and WiFi 6 alongside its 4K front and 2.5K rear cameras. The GKU D600 Pro Max is a compelling alternative if GPS and app-based clip access are priorities, while the GMAIPOP makes more sense if you need the option to record the cabin. Before buying any of them, confirm the card requirements and whether the parking features you want need an extra hardwire kit.
