Latest Discussions & Reviews:
  • Complete Incident Coverage: Imagine you’re driving, and someone merges into your lane from the left or right without looking. With a 4-channel system, you’ll have clear footage of that side impact, not just the front or rear. This can be crucial in proving fault, especially in disputes where it’s often your word against theirs. Reports show that having clear dash cam footage can significantly speed up insurance claims and help avoid fraudulent ones.
  • Parking Lot Protection: This is huge. Most minor bumps and scrapes happen when your car is parked. The Rexing L4, with its parking mode and G-sensor, is designed to detect collisions even when your engine is off. With cameras covering all sides, you’re much more likely to catch the culprit who leaves a dent and doesn’t leave a note.
  • Ridesharing and Commercial Use: If you drive for a rideshare service, or even just carpool frequently, the ability to record the interior of your vehicle is a major plus. The L4’s side cameras are often adjustable, meaning you can pivot them to face the cabin, capturing passenger interactions or interior incidents. This added layer of security protects both you and your passengers.
  • Vandalism Deterrence: Just the presence of a multi-channel dash cam can act as a deterrent. Potential vandals might think twice if they realize their actions are being recorded from multiple angles.
  • Comprehensive Trip Documentation: For road trip enthusiasts or those who just like to review their drives, the Rexing L4 provides a detailed record of everything happening around your vehicle. Some models, like the L4-2K, even include built-in GPS to track your speed and location, adding another layer of data to your recordings.

So, while a single-channel camera might give you some protection, a Rexing 4 channel dash cam truly offers peace of mind by eliminating those vulnerable blind spots.

Diving into the Rexing L4’s Core Features

The Rexing L4 series comes packed with features designed to make your driving and parking experience more secure. Let’s break down some of the most important ones:

Crystal Clear Video Quality

The standard Rexing L4 model records in 1080p resolution on all four channels, giving you high-quality video from every angle. This means that when you zoom in on footage, important details like license plates or facial features should remain clear. There’s also an L4-2K model which bumps up the front camera resolution to 2K, while the other three channels still record in crisp 1080p, offering even more detail where it matters most for forward-facing events.

Ultra-Wide Angle Lenses & IR Night Vision

Each camera in the L4 system boasts a 170° ultra-wide-angle lens. This expansive field of view means you’re capturing more of the road and surroundings, reducing blind spots significantly.

But what about driving at night or in low-light conditions? That’s where infrared IR night vision comes into play. The L4’s side cameras are equipped with IR lights, which are specifically designed to enhance clarity, whether they’re facing the cabin or outward to capture exterior views in the dark. This is super important because accidents don’t just happen in broad daylight.

Parking Mode & Collision Detection G-Sensor

This is a feature that truly sets advanced dash cams apart. The parking mode on the Rexing L4 keeps the dash cam vigilant even when your vehicle is turned off. If it detects a collision or significant vibration thanks to its built-in G-sensor, it automatically starts recording. This footage is then locked and saved in a separate emergency folder to prevent it from being overwritten by normal loop recording. This means your car is protected around the clock. Just remember, for parking mode to work continuously without draining your car battery, you’ll typically need to hardwire your dash cam to your vehicle’s fuse box.

Loop Recording – Never Run Out of Space

You don’t want to constantly manage storage on your dash cam. That’s why the Rexing L4 features loop recording. This handy function ensures continuous recording by automatically overwriting the oldest unlocked footage with new recordings once your memory card is full. So, you never have to worry about running out of space or manually deleting old files, unless you specifically want to save certain clips.

Wi-Fi Connectivity & The Rexing Connect App

The Rexing L4 comes with built-in Wi-Fi, often operating on 5.0 GHz for faster transfers. This allows you to effortlessly connect your dash cam to your smartphone using the Rexing Connect App. What’s so great about that? Well, you can quickly transfer video files to your mobile device, view live footage, manage settings, and even share important clips without ever needing to pull out the SD card. It’s super convenient for reviewing incidents on the spot or backing up files to your phone. Rexing Manhattan Beach: A Personal Journey to Coastal Bliss with Jonpaul Rexing’s Family

GPS Logger Optional/Built-in depending on model

The L4-2K model includes a built-in GPS logger that tracks your speed and location. This data is recorded alongside your video footage, allowing for detailed trip data playback where you can see exactly where you were and how fast you were going at any given moment. For the standard L4 model, a GPS logger is typically an optional accessory that you can purchase separately if you want that extra layer of information.

Supercapacitor for Extreme Temperatures

Many Rexing dash cams, including the L4 series, use a supercapacitor instead of a traditional lithium-ion battery. This is a big deal because supercapacitors are much more reliable in extreme temperatures, both hot and cold. They offer a longer lifespan and reduce the risk of battery-related failures, which can be common with dash cams left in hot cars all day.

Getting Your Rexing L4 Dash Cam Up and Running: Installation Tips

You’ve got your shiny new Rexing L4 dash cam. Now, how do you get it into your car without it looking like a spaghetti monster of wires? The good news is, Rexing designs its dash cams for relatively easy installation. Here are some general tips to get you going:

1. The Right Memory Card is Key

Before you even think about sticking anything to your windshield, make sure you have the right memory card. The Rexing L4-2K, for example, accepts Class 10/UHS-3 or higher Micro SD memory cards up to 256GB. Rexing recommends using cards specifically built for dash cam use, as these are designed to handle constant overwriting and extreme temperatures. Using a cheap, generic, or slow-write-speed card can lead to issues like the rexing dash cam not recording or freezing. Some users have reported issues with certain brands like SanDisk Ultra, suggesting high-performance cards like Kingston Canvas Go Plus are better.

Always format the memory card inside the dash cam before you start using it, and then regularly like once a month to keep it performing optimally.

2. Mounting Your Camera

The Rexing L4 usually comes with both an adhesive mount and a suction cup mount.

  • Adhesive mounts like 3M pads offer a more permanent and secure hold, often preferred for a cleaner look. Make sure to clean the mounting area on your windshield thoroughly with rubbing alcohol and let it dry before applying.
  • Suction cup mounts are great for flexibility if you want to move the camera between vehicles or adjust its position frequently. For a better seal, some manuals suggest applying a little moisture to the suction cup and then waiting about 30 minutes for it to dry and create a strong bond.

Choose a spot that gives the camera a clear view of the road but doesn’t obstruct your driving vision. Many drivers prefer mounting it behind the rearview mirror to keep it discreet.

3. Powering It Up

Your dash cam needs continuous power to record. The L4 comes with a Type-C charging cable that plugs into your vehicle’s 12V DC power outlet cigarette lighter socket. Once plugged in, the camera should auto-start recording when your vehicle turns on.

For that crucial parking mode functionality, where the camera records even when your car is off, you’ll need a hardwire kit. A smart hardwire kit connects directly to your car’s fuse box, providing continuous power while also protecting your car battery from draining by cutting off power if the voltage drops too low. While the instructions for how to install rexing v3 dash cam or similar models often cover hardwiring, the principle is the same across Rexing’s line for parking mode. It’s a bit more involved than plugging into the cigarette lighter, but totally worth it for the added security. Decoding Jason Rexinis: Your Guide to a Commercial Real Estate Maverick

4. Routing Cables Neatly

Nobody wants messy wires hanging everywhere. Use the included cable management tool to tuck the power cable neatly around your windshield trim and under the dashboard. This keeps your interior tidy and prevents the cables from interfering with your driving.

When Things Go Wrong: Common Rexing Dash Cam Problems & Troubleshooting

Even the best tech can have its moments. If your Rexing dash cam not recording or if you’re experiencing other glitches, don’t panic! Many common issues have straightforward solutions.

“My Rexing Dash Cam is Not Recording!”

This is probably the most frustrating issue, but it’s often fixable.

  • Memory Card Full: This is a classic. The loop recording should prevent it, but if you have a lot of locked emergency files, it can fill up. Transfer important files to your computer and then format the card in the dash cam.
  • Unsupported or Faulty Memory Card: As mentioned, not all Micro SD cards are created equal. Ensure you’re using a Class 10/UHS-3 or higher card from a reputable brand designed for dash cams. Cheap cards or ones with slow write speeds can cause recording failures. Test the card in another device to check if it’s faulty, or try a different card altogether.
  • Improper Formatting: Always format the memory card using the dash cam’s internal format function, not just on your computer.
  • Power Issues: An inconsistent or insufficient power supply can interrupt recordings. Double-check your power cable connection and make sure it’s plugged in securely. If you suspect the cable is faulty, try a different one.
  • Firmware Problems: Outdated or buggy firmware can cause recording issues. Check Rexing’s support website for the latest firmware updates for your specific L4 model and follow their instructions carefully. Incorrect firmware can brick your device.

The Rexing Connect app and Wi-Fi are super handy, but sometimes they can be a bit finicky. How to Charge Your Tesla with a J1772 Adapter (And Why You’ll Love It!)

  • Activate Wi-Fi on Dash Cam: Make sure you’ve explicitly turned on the Wi-Fi feature in your dash cam’s settings. The Wi-Fi name SSID and password should then display on the screen. Sometimes the font is small, so look closely.
  • Connect to Dash Cam’s Wi-Fi: On your phone, go to your Wi-Fi settings and select the dash cam’s network. Enter the password. Remember, this Wi-Fi is just for connecting your phone to the camera, not for internet access. Your phone might warn you that there’s no internet. that’s normal.
  • Open Rexing Connect App: Once connected, open the Rexing Connect app and hit the “Connect” button.
  • Wi-Fi Interference: Occasionally, other Wi-Fi signals in the area can cause interference. Try moving your vehicle to a different location.
  • App Limitations: Some users have reported that the Rexing app requires downloading the entire video file before you can view it, which can be slow. This isn’t necessarily a “fixable” issue but something to be aware of.
  • Firmware Update: Ensure your dash cam’s firmware and the Rexing Connect app are both up to date.

“Rexing Dash Cam No Sound”

If your recordings are silent, check a few things:

  • Microphone Setting: Most dash cams have an option to turn the microphone on or off. Check your L4’s settings menu to ensure the audio recording is enabled. Sometimes you’ll see an “OMI/H” icon if the microphone is off.
  • Firmware: Again, an outdated firmware might lead to unexpected issues. A firmware update could resolve this.
  • Faulty Hardware: If all else fails, and you’ve confirmed settings and firmware, it could be a hardware issue with the microphone. In that case, contacting Rexing support would be the next step.

“Dash Cam Not Turning On / Keeps Rebooting”

  • Power Source: Most dash cams are designed to be continuously powered by your vehicle’s 12V outlet. If it turns off shortly after disconnecting, that’s expected. If it’s not turning on at all or constantly rebooting even when connected, check the power cable and the 12V adapter. The fuse in the cigarette lighter adapter can sometimes blow. checking and replacing this fuse can solve the problem.
  • Depleted Internal Battery: While Rexing uses supercapacitors, some older models or specific components might still rely on a small internal battery for settings. A depleted internal battery or a faulty power source could cause rebooting. Try a different power source if possible.
  • Firmware: A corrupt firmware can also prevent the device from booting correctly.

When in doubt, Rexing’s website has a robust troubleshooting section and support channels that can guide you through specific issues for your Rexing L4 dash cam. You can also try restoring your unit to factory settings as a first troubleshooting step.

Frequently Asked Questions

What is a 3-channel dash cam and how does it compare to the Rexing L4?

A 3-channel dash cam typically records the front, rear, and interior cabin views. While it offers excellent coverage for ridesharing or monitoring your car’s interior, it usually doesn’t capture the side exterior views of your vehicle. The Rexing L4 4 channel dash cam, on the other hand, adds two dedicated side cameras which can often be rotated to face the cabin or exterior, providing a truly comprehensive 360-degree external view that a 3-channel system often misses. This extra coverage from the sides can be crucial for incidents like side-swipes or parking lot damage from the left or right.

Can I install the Rexing L4 dash cam myself, or do I need a professional?

Yes, you can definitely install the Rexing L4 dash cam yourself! Rexing designs its dash cams for easy user installation, and they usually come with all the necessary mounting hardware, like adhesive or suction cup mounts, and a power cable that plugs into your car’s cigarette lighter. The trickiest part might be neatly tucking away the cables, but a cable management tool is often included to help with that. If you want to use the parking mode feature, you’ll need to hardwire the dash cam, which involves connecting it to your car’s fuse box. While many DIYers can tackle this with a bit of research, some prefer a professional for hardwiring to ensure it’s done correctly and doesn’t interfere with vehicle electronics.

What should I do if my Rexing dash cam is not loop recording?

If your Rexing dash cam not loop recording, it could be due to a few common issues. First, ensure that loop recording is actually turned “on” in the camera’s settings. If it is, the problem is often related to the memory card. Make sure you’re using a high-quality Class 10/UHS-3 or higher Micro SD card from a reputable brand that’s specifically designed for dash cams. Cheap or faulty cards can struggle with continuous writing. You should also format the memory card inside the dash cam itself, not on a computer, and do this regularly monthly is a good habit. If the card is full of “locked” event files triggered by the G-sensor, manually delete or transfer them to free up space. Finally, check Rexing’s website for any firmware updates, as these can sometimes resolve recording glitches.

Why is my Rexing dash cam Wi-Fi not working with the app?

When your Rexing dash cam Wi-Fi not working with the Rexing Connect app, it’s usually a connection issue rather than a broken feature. First, ensure the Wi-Fi is enabled on your dash cam via its settings, and note the displayed SSID network name and password. Then, on your smartphone, go into your phone’s Wi-Fi settings and manually connect to the dash cam’s Wi-Fi network using that password. Remember, this is a direct connection between your phone and the camera, so your phone might show it as having “no internet” – that’s normal. Once connected, open the Rexing Connect app and select “Connect.” If you’re still having trouble, try restarting both your phone and the dash cam, make sure both the dash cam’s firmware and the app are updated to the latest versions, and try connecting in a different location to rule out Wi-Fi interference.

Does the Rexing L4 record audio, and can I turn it off?

Yes, the Rexing L4 dash cam does record audio, which can be very helpful for capturing a full account of any incident. However, if you prefer not to record audio, you can usually turn this feature off within the dash cam’s settings menu. Look for a microphone icon or an “audio recording” option in the settings. This gives you control over your privacy while still benefiting from the video evidence.

What is the advantage of a supercapacitor in the Rexing L4 over a traditional battery?

Many Rexing dash cams, including the L4 series, utilize a supercapacitor instead of a traditional lithium-ion battery. The main advantage is significantly improved reliability and lifespan, especially in extreme temperatures. Lithium-ion batteries can degrade quickly in very hot e.g., inside a parked car in summer or very cold conditions, leading to battery swelling, reduced performance, or even complete failure. A supercapacitor, on the other hand, is much more robust and stable across a wider temperature range, ensuring your dash cam continues to operate reliably day in and day out, year after year. While it doesn’t hold a charge for long periods when unplugged like a battery, it’s perfect for powering down safely after the ignition is off and for consistent performance during operation.
