2. Product Features and Operation
2.1 Night Vision with WDR Technology
The AC-FCR04W camera incorporates Night Vision with Wide Dynamic Range (WDR) technology. This feature allows the camera to capture clear details, such as license plates and road signs, even in challenging low-light conditions. Strong Light Suppression further enhances image and video clarity by reducing glare distortions from bright lights.

2.2 150° Wide Angle View
The camera provides a 150-degree wide-angle field of view, which helps to minimize blind spots and capture a broader perspective of the road ahead. This wider coverage can be beneficial for recording events and monitoring surroundings.

2.3 Loop Recording and Storage
The AC-FCR04W supports loop recording, which automatically overwrites the oldest files when the storage card is full. This ensures continuous recording without the need for manual deletion. The camera supports a maximum of 128GB TF (microSD) card (not included) for extensive storage capacity.

5. Maintenance
To ensure optimal performance and longevity of your ATOTO AC-FCR04W camera, follow these maintenance guidelines:
- Cleaning the Lens: Regularly clean the camera lens with a soft, lint-free cloth to remove dust, dirt, or smudges that may affect video quality. Avoid using abrasive cleaners.
- Cable Inspection: Periodically check the extension cable for any signs of wear, damage, or loose connections. Ensure all connections are secure.
- Software Updates: Keep your ATOTO head unit's firmware and the DVR App updated to ensure compatibility and access to the latest features and improvements.
- Storage Card Management: Format the TF card periodically (e.g., once a month) to maintain optimal recording performance and prevent data corruption. Back up any important footage before formatting.
6. Troubleshooting
If you encounter issues with your ATOTO AC-FCR04W camera, consider the following troubleshooting steps:
- No Image/Video Display:
- Ensure the camera is correctly connected to the ATOTO head unit.
- Verify that the head unit is powered on and the DVR App is launched.
- Check the camera's power connections (Accessory/Ignition and Ground).
- Poor Video Quality:
- Clean the camera lens.
- Ensure the camera is securely mounted and not vibrating.
- Check the video resolution settings in the DVR App.
- Recording Issues:
- Ensure a compatible TF card is inserted and properly formatted.
- Check if the TF card is full; if so, the loop recording should overwrite old files, but a full card might cause issues if not properly managed.
- Verify the recording settings in the DVR App.
- Compatibility Issues:
- Confirm your ATOTO head unit model is listed as compatible (S8 MS/PN/UN series).
- Note that S8 PN models only support front-view monitoring, not recording or shooting.
