Car Security Camera Indicator Light Troubleshooting: Fixing Red & Blue Flashing Issues

The Lamtto DC22 Wireless dash cam is more than just a dash cam; it's an advanced car security camera that provides unprecedented vehicle safety through its 4G LTE network. Whether it's for live remote monitoring, GPS tracking, or radar-based collision detection during parking, the DC22 is designed to give you complete peace of mind.

However, when you first install or use this powerful device, you might be confused by the status of its indicator lights, especially when they start flashing or show unusual colors. Red light off? Blue light constantly blinking? What do these signals actually mean?

Don't worry, you're not alone. This ultimate guide will break down the language of the Lamtto DC22's indicator lights and provide a complete, detailed set of troubleshooting steps to help you quickly diagnose and resolve issues, getting your car security camera back to its optimal working condition.

Part 1: The Basics - Understanding the car security camera's Indicator Light Language

Before we can solve a problem, we first need to understand what the indicator lights mean under normal circumstances. The DC22 primarily uses red and blue lights to communicate its operational status.

Indicator Light	Status	Meaning
Blue Light	Solid On	Network Normal: The device is successfully connected to the 4G LTE network.
	Slow Flashing	Searching for Network: The device is searching for an available 4G signal.
	Fast Flashing	Connecting: The device has found a signal and is attempting to dial up and connect to the network.
	Off	Network Module Off or No SIM/Plan: The network function is not activated or is unavailable.
Red Light	Solid On	Normal Recording: The device is currently performing loop recording.
	Flashing	Event Recording: The G-Sensor or radar has detected a collision, vibration, or movement, triggering an emergency event recording.
	Off	Recording Stopped or Device in Sleep Mode: The device may be in standby mode or not powered on.

By understanding these basic statuses, we can more effectively pinpoint the source of a problem.

Part 2: Common Issues and Step-by-Step Solutions

Next, we will address the most common indicator light abnormalities reported by users and provide detailed troubleshooting steps.

Issue 1: Red Light is Off or Flashing Abnormally (Recording Function Failure)

The red light is directly related to the device's core function—video recording. If it's not on, it means your drive may not be getting recorded.

Possible Causes:

1. Power connection issue.

2. MicroSD (TF) card failure or incompatibility.

3. Device firmware or hardware malfunction.

Solutions:

Step 1: Check the Power Connection
The car security camera uses an OBD power cable to achieve 24/7 parking monitoring. Ensure the OBD connector is securely plugged into your vehicle's OBD port and that the cable has no visible physical damage. You can try unplugging and replugging it to ensure a solid connection.

Step 2: Check and Manage the MicroSD Card
The SD card is one of the most common failure points for any car security camera.

· Confirm the SD Card is Inserted: Make sure the SD card is correctly inserted into the DC22's card slot.

· Format the SD Card: Long-term use can create file fragments that may lead to read/write errors. You can find the format option in the "UBoxPro" app, or you can remove the SD card and use a computer (with a card reader) to format it to FAT32. Please note: Formatting will erase all recordings on the card, so back up important files beforehand.

· Replace the SD Card: According to the product page, the DC22 supports a maximum SD card size of 128 GB. If the problem persists after formatting, try replacing it with a high-speed (Class 10 or higher) MicroSD card from a reputable brand. Low-quality or low-speed cards are a common culprit for recording failures.

Step 3: Reboot the Device
Disconnect the OBD power, wait for about 30 seconds, and then reconnect it to allow the device to perform a full reboot. This simple action can resolve many issues caused by temporary software conflicts.

Issue 2: Blue Light is Continuously Flashing or Off (4G Network Connection Failure)

As a 4G car security camera, the DC22's remote capabilities are entirely dependent on a stable network connection. An abnormal blue light means you won't be able to use core features like live view, remote calls, GPS tracking, and cloud backup.

Possible Causes:

1. The vehicle is in a 4G signal blind spot.

2. The 4G data plan has expired or run out of data.

3. The SIM card is not activated or is malfunctioning (the DC22 has a built-in, non-removable SIM card).

Solutions:

Step 1: Check Vehicle Location and Signal Strength
Drive your vehicle to an open area, away from underground parking garages, tunnels, or areas shielded by tall buildings. 4G signal is often weak or non-existent in these locations. In an open area, give the device a few minutes to search for and connect to the network again.

Step 2: Verify Your 4G Data Plan Status
This is the most critical step. According to the Lamtto website, the DC22 comes with a 7-day unlimited data trial. After the trial period ends, you must subscribe to a data plan within the "UBoxPro" app to continue using the remote functions.

· Plan Options: $19.90/month, $99.99/six months, or $169.90/year.

· How to Check: Open the "UBoxPro" app and navigate to the device settings or account management section to check if your subscription is active. If it has expired, renew it immediately.

Step 3: Understand Usage Without a Plan
According to the official FAQ, if your data plan expires and you don't renew it, the DC22 can still function as a traditional dash cam. It will continue to save recordings to the SD card, but you will lose all remote functionality, and the blue light will turn off. In this state, you can only view recordings by using a card reader on a computer.

Step 4: Contact Technical Support
Since the DC22's SIM card is built-in and cannot be replaced, if the blue light still fails to work after you've ruled out signal and data plan issues, it may indicate a hardware problem with the SIM card or network module.

Part 3: Advanced Troubleshooting & Frequently Asked Questions (FAQ)

This section integrates common questions from the official website and supplementary guide page to provide you with more comprehensive information.

Q1: Why is the live video feed in the app blurry?
A: This is normal. To ensure smooth streaming across different network conditions, the live preview in the app is compressed, resulting in a lower resolution. This does not affect the quality of the original video recorded to the SD card. As stated in the product page FAQ, to view the original 1080p full HD recordings, please remove the SD card and play the files on a computer using a card reader.

Q2: How do the G-Sensor and parking monitor work?
A: The DC22 combines a G-sensor and microwave radar for dual detection. While driving or parked, if the G-sensor detects a sharp jolt (like a collision or sudden braking) or the radar detects movement in front of the vehicle, the device immediately triggers an "Event Recording." The red light will flash, that video segment will be locked to prevent it from being overwritten by loop recording, and it will be automatically uploaded to the cloud (requires an active data plan). You will also receive an alert on your phone's app. This is precisely what makes it an excellent car security camera.

Q3: What happens when the SD card is full?
A: No need to worry. The DC22 supports Loop Recording. When the SD card's storage is full, the device will automatically overwrite the oldest normal recording files with the newest ones. Emergency event videos, which are locked by the G-sensor or manual lock button, will not be overwritten.

Q4: Can I share the device with my family?
A: Yes. Your family members just need to download the "UBoxPro" app. You can then use the "Share Device" feature within the app to grant them access to the camera.

Conclusion: Keep Your Car Security Camera Vigilant at All Times

The Lamtto DC22 is a powerful automotive security device, and its indicator lights are the most direct window into its health status.

To summarize, when you encounter an indicator light issue, follow these golden rules:
