2. Inserting the MicroSD Card
The device supports MicroSD cards up to 256GB (not included). Ensure the card is formatted to FAT32 for best compatibility. Locate the MicroSD card slot on the camera module and gently insert the card until it clicks into place.

Operating Instructions
Powering On/Off
To power on the device, slide the 'ON/OFF' switch to the 'ON' position. To power off, slide the switch to 'OFF'.
Recording Modes
The Atom 4K supports both continuous recording and motion-activated recording.
- Continuous Recording: Once powered on, the device can be set to record continuously. Refer to the remote control section for activation.
- Motion-Activated Recording: When motion is detected within the camera's 120° field of view, the camera automatically begins recording and saves footage to the MicroSD card. This mode conserves battery life and storage space.

Using the Remote Control
The included remote control allows for discreet operation from up to 60 feet away. Use the buttons on the remote to start/stop recording or activate/deactivate motion detection.
Loop Recording
The Atom 4K supports loop recording. When the MicroSD card is full, the camera will automatically overwrite the oldest files, ensuring continuous recording without manual intervention. Video files are saved in segments, typically every 10 minutes, with each hour of 4K footage consuming approximately 9-10GB.

Date & Time Stamps
Date and time stamps can be optionally displayed in the corner of recorded videos or photos. This feature is useful for evidence collection and chronological organization of footage.
Maintenance
Battery Care
To prolong battery life, avoid extreme temperatures and fully charge the battery before long periods of inactivity. The lithium-ion battery is rated for 500,000 cycles.
Storage Management
Regularly back up important footage from your MicroSD card to a computer or external storage device. Periodically format the MicroSD card to maintain optimal performance and prevent data corruption.
Troubleshooting
- Device not powering on: Ensure the battery is fully charged. Check that the 'ON/OFF' switch is in the 'ON' position.
- No recording: Verify that a MicroSD card is properly inserted and has sufficient free space. Check if the card is formatted correctly (FAT32). Ensure the recording mode (continuous or motion-activated) is correctly activated via the remote control.
- Poor video quality: Ensure the camera lens is clean and free from obstructions. Verify that the lighting conditions are adequate.
- Remote control not working: Check the remote control's battery. Ensure you are within the operational range (up to 60 feet) and there are no significant obstructions.
