I kept this item in storage without using it because I didn't know how to use it. It is new and unused, but the box is dirty. I purchased it for around 10,000 yen at the time. I have opened it to check the operation. When using it, please open it and remove the insulation sticker from the battery inside the main unit. Please understand that this is a used item and may have aged over time. Thank you! Smart clock with HD video and audio, and infrared function. - Model Name: Smart Clock - Functions: HD video and audio, mobile device recording, infrared function - Setup: Easy mobile device setup - Recording Function: Saves live video to smartphones and tablets Thank you for viewing.
