Good fit for

This dash cam suits drivers who want full vehicle coverage, including interior and side views. The four-camera setup is ideal for ride-share drivers or those parking in high-traffic areas. You will appreciate the included 64GB card and Wi-Fi app for quick clip retrieval. The infrared night vision helps in dimly lit garages. If you need broad recording angles and easy smartphone access, this system fits your needs well.

Who can skip it

Skip this model if you require 4K resolution, as it records only in 1080p. You should look elsewhere if you want a battery-powered unit, as this device requires constant USB Type-C power. It also lacks built-in GPS, so it cannot track your location or speed. Additionally, parking mode requires a separate Smart Hardwire Kit. If you prefer a simpler, all-in-one package without extra accessories, this may not be the right choice.

Verdict

The REXING C4 offers solid 1080p coverage for drivers needing multiple camera angles. It is a practical choice for those who value app control and included storage over higher resolution or GPS tracking.

Key specs explained for the C4

4-Channel Camera Configuration

This unit captures four simultaneous video feeds, typically covering the front, rear, and both side exterior angles, plus an interior cabin view. You get a complete record of your vehicle's surroundings from every direction. This setup is ideal for rideshare drivers or fleet managers who need full coverage. Standard single-camera dash cams only record one angle, missing critical context from other sides of the car.

1080p Video Resolution

Each of the four cameras records video at 1920×1080 pixels. This standard definition provides clear enough detail to read license plates in most daylight conditions. While 4K cameras offer sharper images, 1080p balances file size and clarity. You benefit from manageable storage usage while still getting usable footage for insurance claims or dispute resolution compared to lower 720p options.

64GB Included Storage

The package includes a 64GB microSD card, allowing immediate use without buying extra accessories. This capacity stores several hours of 1080p footage before loop recording overwrites the oldest files. You do not need to purchase storage separately. When shopping, verify if your chosen camera includes a card, as many models require you to buy a high-endurance card separately for reliable operation.

Wi-Fi Connectivity

The camera creates a local Wi-Fi network that your smartphone connects to via the Rexing Connect app. You can review recordings, download clips, and change settings without removing the memory card. This feature simplifies managing footage on the go. Compare this to older models requiring USB cables and computers for file transfer, which is slower and less convenient for quick review.

Physical design and build specs

According to the listing, the Rexing C4 unit measures 5.51 inches in length, 2.76 inches in width, and 1.97 inches in height. It weighs five ounces. This compact footprint allows you to mount it discreetly behind your rearview mirror without obstructing your view. The small size also makes it less noticeable to potential thieves.

The camera is battery-free and relies on a USB Type-C power connection. You must connect it to an external power source during operation. This design choice means the unit does not overheat or degrade from internal battery cycling, but it requires constant vehicle power. You can choose between the included adhesive mount or the suction cup mount for positioning. The adhesive option offers a permanent, vibration-resistant fix, while the suction cup allows for easier repositioning.

Controls are handled entirely through the Rexing Connect app via Wi-Fi. There are no physical buttons on the main unit. You review recordings, download clips, and adjust settings directly from your smartphone. This layout keeps the hardware clean and simple, though it requires you to have your phone ready to make changes or retrieve footage.

Setup and everyday use guide

The Rexing C4 operates without an internal battery, so it requires a continuous external power source to function. You will need to connect the unit using the included USB Type-C cable. For installation, you can choose between the adhesive mount or the suction cup mount provided in the box. This flexibility allows you to position the camera discreetly behind your rearview mirror or on the windshield, depending on your preference and vehicle layout.

Once powered, you manage the system through the Rexing Connect app on your smartphone. The camera features local Wi-Fi connectivity, meaning you connect your phone directly to the device to review footage, download clips, or adjust settings. You do not need a cellular connection for these tasks. The bundle includes a 64GB microSD card, which handles storage automatically. Loop recording ensures that older, unlocked videos are replaced as space fills up, keeping the system running without manual intervention.

For daily driving, the four simultaneous 1080p views capture your surroundings comprehensively. The cabin and side cameras include infrared night vision to maintain visibility in low light. If you leave your vehicle parked, the G-sensor detects impacts and locks those specific clips so they are not overwritten. Parking mode is also available, but it requires a compatible Smart Hardwire Kit sold separately to provide the necessary continuous power. This setup ensures your footage is secure during both driving and stationary periods.

Before You Buy This Dash Cam

Owning this four-channel system requires a few extra steps. The listing notes that parking mode needs a Smart Hardwire Kit, which is sold separately. You must verify your vehicle’s electrical system supports this installation before purchasing. Since the unit lacks an internal battery, it depends entirely on continuous external power via the USB Type-C port. This means it stops recording if the car’s power cuts out unexpectedly. You should also check if your smartphone is compatible with the Rexing Connect app for Wi-Fi control. Regular upkeep involves managing the 64GB microSD card. Loop recording overwrites old files, but you may need to format the card periodically to maintain performance. This setup suits drivers who want full coverage. It fits well among other car electronics for those prioritizing comprehensive recording over portability.

Check before you buy

• Confirm your car supports the required Smart Hardwire Kit for parking mode.
• Check your smartphone compatibility with the Rexing Connect Wi-Fi app.
• Verify your vehicle’s electrical system handles continuous USB Type-C power draw.
• Ensure you have space for four camera mounts inside and outside.
