Quick start

Use this alongside the manual for your exact model. Back up important recordings before formatting a card or changing firmware. Check mounting guidance from your helmet or bike manufacturer.

Step 1: Fully charge the camera

Before first use, fully charge the LC-2 Pro using the included Type-C cable and a 5V/2A power adapter. The blue indicator light stays on while charging and turns off when complete.

Step 2: Insert a memory card

1. The LC-2 Pro requires a microSD card with a maximum capacity of 128GB and a minimum write speed of U3/V30.

2. Insert the card into the microSD card slot until it clicks into place.

Step 3: Power on and basic functions

1. Power On/Off: Press and hold the Power Button (1).

2. Start/Stop Recording: The camera begins recording automatically on power-up (Green light blinking).

3. Cycle Light Modes: Press and hold the LED Light Button (3) to turn the light on/off. Short press to cycle through the 6 light modes.

Step 4: Pair with the Viidure app

1. Download the Viidure app from the Google Play or App Store by scanning the QR code on the packaging.

2. Power on the LC-2 Pro.

3. Short press the Power/Wi-Fi Button (1) to enable Wi-Fi. The indicator light will blink red.

4. On your phone's Wi-Fi settings, connect to the network: LC2-PRO_XXXXXX.

5. Enter the password: 12345678. The indicator light will turn solid red.

6. Open the Viidure app. You can now view live video, change settings, and download your files.

SD and TF cards:

▪ Important: Before using the camera, insert a formatted card or format the card via the Viidure app.

▪ Regular Maintenance: To maintain optimal performance, format your SD card at least once a month.

▪ How to Format: Connect to the camera via the app, go to [Camera Settings], and select [Format Memory Card].

Important Notes:

▪ Backup Files: Formatting will delete ALL files on the card. Back up any important footage first.

▪ Card Lifespan: SD cards have a finite lifespan. Because loop cameras write data constantly, we recommend high-quality "Endurance" cards. If you experience file errors, it may be time to replace your card.

Wi-Fi & App Guidance

Why is my phone saying "No Internet Connection" when connected to the LC-2 Pro?

This is normal. Your phone is connected to the LC-2 Pro’s Wi-Fi network, not the internet.

The Viidure App isn’t connecting—what should I do?

Ensure:

The LC-2 Pro is turned on and Wi-Fi is enabled
Your phone is connected to "Techalogic" Wi-Fi network (Check your phone settings).
If prompted, select "Keep" when your phone suggests switching Wi-Fi networks.

Recording & Video

Does the LC-2 Pro overwrite old footage?

Yes, loop recording automatically overwrites old files unless they are locked.

How do I lock a file to prevent it from being deleted?

The LC-2 Pro automatically locks files in the event of an impact (G-Sensor detection). You can also manually lock a file through the Viidure App.

Why are some files locked and not being overwritten?

These are impact-detected (G-Sensor) videos. You can delete them manually via the app or SD card.

Troubleshooting

The LC-2 Pro isn’t turning on—what should I do?

Try the following:

Charge the battery fully.
Reset the device using the reset button.
Ensure the power button is held down for 2 seconds.

Why is my LC-2 Pro not recording?

Ensure:

A compatible SD card is inserted.
The SD card is formatted correctly.
The Recording Button has been pressed (Green light flashing = recording).

The light isn’t turning on automatically at night—why?

Check if Twilight Sensor Mode is enabled in the Viidure App.
