Bresser Digital Night Vision Binoculars 3x With Recording Function

The effective night vision range with the integrated infrared illuminator is approximately 120 meters.

Yes, the binocular viewing design makes it comfortable for spectacle wearers.

The device supports MicroSD cards up to a maximum size of 64GB.

Yes, the device features a recording function for both video (AVI format) and photos (JPG format).

The built-in rechargeable battery provides up to 8 hours of operation on a single charge.

You can charge the device using the included USB charging cable connected to a 5V power source or a commercial power bank. Simultaneous observation and charging are possible.

The device has 3x optical magnification for a clear, magnified image. The 3x digital zoom further enlarges the image digitally, which may result in a loss of image quality.

Ensure the battery is charged. Connect the USB charging cable to a reliable power source and charge for at least 2 hours. Check if the power button is being pressed correctly.

Activate the integrated infrared (IR) lighting. Increase the IR brightness level through the menu settings. Ensure the night vision distance range (up to 120m) is not exceeded.

Verify that a compatible MicroSD card (formatted correctly) is inserted. Ensure the card is not full and has sufficient write speed. Check the device settings to confirm recording mode is active.

Adjust the focus manually if applicable (though not explicitly stated, often a feature). Ensure the lenses are clean. For digital zoom, understand that image quality may decrease.

Reduce the brightness of the IR illuminator if possible. Ensure the device is fully powered off when not in use. Continuous recording or high IR settings will consume power faster.
