Understanding Your Rexing Dash Cam Cable Needs

When you first unbox a Rexing dash cam, you’ll notice a few different cables, and it can be a bit confusing to know what each one does and when to use it. Think of these cables as the lifelines of your dash cam, each serving a specific purpose to keep your device powered, connected, and recording.

Types of Rexing Dash Cam Cables

Rexing dash cams typically come with a few essential cables, and there are others you might want to pick up depending on your setup.

Standard Power Cable Cigarette Lighter Adapter: This is probably the most common Rexing dash cam cord you’ll see. It plugs into your car’s 12V DC outlet, often referred to as the cigarette lighter port. This cable powers your dash cam while your car is running, and usually, the dash cam will turn on and start recording automatically when it receives power. This is the simplest plug-and-play option.
Rexing Dash Cam USB Cable: Now, this one can be a bit tricky. Many Rexing dash cams use a Mini-USB or Type-C port for power. While some cables might look like a standard USB charging cable, the one included with your dash cam, especially the longer one, is designed for in-car power. There’s usually a shorter USB cable with a full-size USB end that’s specifically for connecting your dash cam to a computer to transfer files. Using your car’s built-in USB port for constant power often doesn’t work well because those ports might not provide enough stable power, leading to your dash cam constantly turning on and off. Always use the dedicated car charger for consistent power.
Rear Camera Cable: If you have a dual dash cam setup front and rear, you’ll have a specific Rexing dash cam wire to connect the rear camera to the main front unit. This cable transmits both power and video signals.
Extension Cables: Sometimes the included cables aren’t long enough, especially for larger vehicles or if you want to route wires very discreetly. That’s where Rexing dash cam extension cables come in handy. We’ll chat more about these later.
Hardwire Kit: For the most professional and functional installation, a Rexing dash cam hard wire kit is usually the way to go. This bypasses the cigarette lighter entirely and connects directly to your car’s fuse box, offering benefits like parking mode.

Why Cable Quality Matters

You might think “a cable is a cable,” but with dash cams, quality makes a real difference. A cheap, generic cable might not provide the stable power your Rexing dash cam needs, which can lead to frustrating issues like the camera randomly shutting off or not recording properly. Rexing-approved chargers and cables are specifically designed to meet the power requirements of their devices, ensuring reliable operation. Think of it like this: your dash cam is your silent witness on the road, and you don’t want it to take an unscheduled break because of a faulty connection!

Standard Power Cable Cigarette Lighter Adapter

Most Rexing dash cams come with a power cable that plugs into your car’s 12V DC auxiliary power outlet the cigarette lighter. This is the easiest way to get your dash cam up and running. Once you start your car, the dash cam usually powers on automatically and begins recording.

Pros:

Easy Installation: Just plug it in.
Portable: You can easily move the dash cam between vehicles.

Cons:

Visible Wires: The cable often dangles from the dash cam to the power outlet, which some people find untidy.
No Parking Mode usually: Most 12V outlets turn off when your car engine is off, meaning your dash cam won’t record when parked.
Occupies a Port: You lose a power outlet in your car.

A common Rexing dash cam power cord is usually around 11-13 feet long, giving you some room to neatly tuck the wire around your windshield and A-pillar. Navigating a Rexing Warranty Claim: Your Ultimate Guide

Rexing Dash Cam USB Cable for Power & Data Transfer

Here’s an important distinction: the short USB cable included with your dash cam is primarily for connecting to a computer. When you plug your dash cam into your computer with this cable, you can access the memory card as “Mass Storage” to transfer video files.

The longer cable with the Mini-USB or Type-C end that plugs into the dash cam and the car charger is the power delivery cable. While it has a USB-style connector on the dash cam side, it’s designed to work with the specific car power adapter. Trying to use a generic USB cable with your car’s built-in USB port often leads to problems. Many vehicle USB ports don’t supply enough consistent amperage e.g., 2A is common for dash cams or might cycle power, causing the dash cam to reboot repeatedly. If your dash cam is constantly turning on and off when plugged into a car’s USB port, this is likely why.

So, to avoid headaches, always use the dedicated Rexing car charger that comes with your dash cam for power, even if it has a Mini-USB or Type-C connector at the dash cam end.

When to Replace Your Power Cable Rexing Dash Cam Cord Replacement

Cables can wear out over time. If your Rexing dash cam is acting strange – like constantly restarting, not turning on, or intermittently losing power – a faulty power cable is often the first culprit to check.

Signs you might need a Rexing dash cam cord replacement: Rexing camera warranty

Intermittent Power: The dash cam turns on and off by itself.
Not Charging/Powering: The dash cam doesn’t light up or respond when plugged in.
Damaged Cable: Visible fraying, bends, or damage to the cable or plug.

You can find replacement Rexing dash cam power cables directly from Rexing USA’s website or through retailers like Amazon, Best Buy, and Walmart. It’s always best to get an original or approved replacement to ensure compatibility and reliable performance.

The Hardwire Route: A Clean and Constant Power Supply

If you’re serious about your dash cam’s protection, especially when your car is parked, then a Rexing dash cam hard wire kit is a must. It provides a much cleaner installation and unlocks crucial features like parking mode.

What is a Hardwire Kit and Why Use One?

A hardwire kit connects your dash cam directly to your vehicle’s fuse box, bypassing the cigarette lighter port. This setup typically consists of a control box and three wires: a constant power wire, an ignition-switched ACC power wire, and a ground wire.

24/7 Parking Surveillance: This is a big one! When hardwired, your dash cam can remain powered even when your car is off, allowing it to record incidents like hit-and-runs or vandalism while parked. Most Rexing hardwire kits offer low voltage protection, which means they’ll automatically cut power if your car battery drops below a certain voltage e.g., 11.8V or 23.5V for 12V/24V systems, ensuring you can still start your car.
Clean Installation: No dangling wires from the cigarette lighter. The cables are neatly tucked away, creating a much more integrated look.
Free Up Power Ports: You retain your car’s 12V outlet for other devices.
ACC Feature: Many smart hardwire kits have an ACC detection feature, automatically switching the dash cam to parking mode when the engine is off and back to normal recording when you start the car.

Choosing the Right Rexing Hardwire Kit

Rexing offers various hardwire kits, and compatibility is crucial. You’ll often find kits specifically designed for certain models or connector types Mini-USB or Type-C. For instance, some kits are for Rexing R4, DT2, M2 Max, and RH2 series Type-C, while others are for older Mini-USB models. Always double-check your dash cam’s manual or Rexing’s product pages to ensure you get the correct kit.

Some Rexing hardwire kits also include a GPS logger, which can track your vehicle’s speed and location for detailed trip playback. Many kits also come with essential installation tools like fuse tap cables add-a-circuit adapters and a plastic crowbar for tucking wires.

Step-by-Step: How to Hardwire Your Rexing Dash Cam

Hardwiring might sound intimidating, but it’s a DIY project many drivers successfully tackle. Here’s a general rundown. always refer to your specific Rexing hardwire kit’s instructions and your car’s fuse box diagram.

Mount Your Dash Cam: First, pick the perfect spot for your front dash cam, usually behind the rearview mirror, making sure it doesn’t block your view. If you have a rear camera, mount that too.
Plan Your Wire Route: Start from the dash cam and plan how you’ll run the Rexing dash cam wire discreetly. A common route is along the headliner, down the A-pillar the pillar next to your windshield, and then under the dashboard to the fuse box. Use the included trim tools or a plastic pry tool to gently tuck wires under the trim.
Locate Your Fuse Box: Your car’s fuse box can be in a few different places: under the dashboard, in the glove compartment, or under the hood. Consult your car’s owner’s manual to find its exact location and diagram.
Identify Constant and ACC Fuses: This is probably the most critical step. You need to find two types of fuses:
- Constant Fuse Yellow Wire on Hardwire Kit: This fuse provides power even when your car is off. It’s for enabling parking mode. Test fuses with a circuit tester multimeter to see which ones are “always hot.” Avoid essential safety fuses like those for airbags, ABS, or the ECU. Good options are often those for the radio, interior lights, or an unused fuse slot.
- ACC Accessory Fuse Red Wire on Hardwire Kit: This fuse only gets power when your ignition is on. This tells your dash cam when the car is running. Again, use a circuit tester to find a fuse that turns on and off with your ignition.
- Connecting with Fuse Taps: Your hardwire kit will come with fuse taps add-a-circuit adapters. These allow you to safely tap into an existing fuse slot without cutting any wires. You insert your chosen fuse into one slot of the tap and the hardwire kit’s fuse into the other. Make sure the outer prong of the fuse tap aligns with the powered side of the fuse slot.
Connect the Ground Wire Black Wire: The black wire from the hardwire kit needs to be connected to a metal bolt or screw on your car’s chassis, preferably near the fuse box. This provides a safe ground. Ensure it’s connected to bare metal, not painted surfaces or plastic.
Connect to Your Dash Cam: Plug the Mini-USB or Type-C end of the hardwire kit into your Rexing dash cam’s power port.
Test the Setup: Start your car. The dash cam should power on and begin recording. Turn off your car. The dash cam should switch to parking mode if enabled or shut down after a short delay, confirming the ACC and constant power connections are working correctly.
Tidy Up: Secure all wires with cable clips or zip ties, ensuring they don’t interfere with pedals or airbags. Make sure all trim pieces are reinstalled securely.

For visual learners, Rexing USA’s YouTube channel has detailed installation guides for their hardwire kits.

Extending Your Reach: Rexing Dash Cam Extension Cables

Sometimes, the standard cables just aren’t long enough. This is especially true for rear cameras in larger vehicles, or if you want to be extra meticulous about wire concealment.

When You Need an Extension Cable

You’ll typically consider a Rexing dash cam extension cable in a few scenarios:

Large Vehicles: If you drive an SUV, truck, or van, the rear camera cable that comes with your dash cam might not reach from the front unit to the rear windshield. Owners of F150 pickups with a cap, for example, often need a longer cable for the rear camera.
Discreet Routing: For a truly invisible installation, you might need extra length to route cables deeply within the vehicle’s interior trim, under carpets, or through specific channels.
Specific Dash Cam Models: Some Rexing models like the V1P Gen 3 and V1P Pro have specific rear camera extension cables available, with lengths up to 33 feet.

Rear Camera Extension Cables

Most dual-channel Rexing dash cams include a rear camera cable, often with a 2.5mm jack on one end and a matching connector for the front camera. If this isn’t long enough, Rexing offers specific extension cables. For instance, the V1P can use a 3.5mm male-to-female extension cable for its rear camera. It’s important to use the correct type and connector for your specific Rexing model to ensure proper video signal and power delivery.

Considerations for Extension Cable Length and Compatibility

Length: Rexing offers various lengths, such as 33-foot extension cables for specific models like the V1P Gen 3 and V1P Pro. Measure your required length carefully, accounting for curves and tucking.
Connector Type: Always verify the connector type e.g., Mini-USB, Type-C, 2.5mm, 3.5mm on both your dash cam and the extension cable to ensure compatibility. Using the wrong connector or an unapproved cable could damage your device or result in poor performance.
Signal Quality: For rear camera extension cables, especially longer ones, signal quality can sometimes be an issue with generic cables. Stick to Rexing-branded or highly-rated third-party options to avoid video interference or degradation.

Troubleshooting Common Cable Issues

Even with the best setup, you might encounter issues. Often, the problem lies with the cables.

Dash Cam Not Powering On

Check the Connection: Is the power cable securely plugged into both the dash cam and the car’s power outlet or hardwire kit? Wiggle it gently to see if there’s an intermittent connection.
Car Outlet Functionality: Test your car’s 12V outlet with another device to ensure it’s working. If you’re hardwired, check the fuse taps and ensure the fuses are intact.
Cable Damage: Inspect the entire length of the Rexing dash cam power cable for any visible damage like kinks, cuts, or frayed wires. A damaged cable won’t deliver consistent power.
Compatibility: Are you using the original Rexing power cable or an approved replacement? Generic USB cables, as mentioned, often fail to provide enough power.

Loose Connections

This is a common headache. If your dash cam keeps turning off and on, or you lose video from your rear camera, a loose connection is a prime suspect. Rexing wireless apple carplay review

Dash Cam Port: The Mini-USB or Type-C port on the dash cam itself can sometimes become loose. If holding the cable in a specific position makes it work, the port or cable might be faulty.
Car Power Outlet: The cigarette lighter adapter can sometimes sit loosely in the car’s port, especially if it’s old or the port is worn.
Hardwire Connections: If hardwired, double-check the fuse tap connections and the ground wire attachment. Ensure they are secure.

Interference Issues

Sometimes, a poorly shielded cable can pick up electrical interference, leading to distorted video or audio. This is less common with original Rexing cables, but if you’re using a generic Rexing dash cam wire or a very long, low-quality extension, it could be a factor. Ensuring proper routing away from other electrical components can also help.
