The original AC adaptor of EYE-02 or EyeSee is DC 6 V. But the camera can also use more common DC 5 V adaptors. In case of using 5 V adaptor do not use the power extension cable. The voltage at the end of long cable would be too low for the camera.

You can also power the camera directly from USB cable. The current from the USB port should be at least 500 mA. For more information about powering EYE-02 or EyeSee camera from external battery or solar panel click here.
