Thank you for viewing. This is a wireless intercom that requires no installation. You'll receive notifications on your smartphone, allowing you to speak with visitors even when you're away. It also comes with a separate chime, so it can be used as a regular, installation-free intercom. It was opened once and used for only about a week, so there are some remaining sticker marks on the back of the camera that couldn't be completely removed. However, the product is in good condition and works perfectly. All accessories are included except for the adhesive stickers, and we are offering it at a low price. If you don't mind this, or if you'd like to try it out, please consider it. 【High-Performance Camera】 Equipped with an XTU wide-angle lens, it covers a wide area. You can clearly see visitors' faces, making it ideal for crime prevention. 【Easy Installation】 Designed for installation at various angles. You can choose the best position for your home's door. 【Complete Accessories】 Includes a wireless chime and a Japanese instruction manual, so you can start using it right away. - Brand: XTU - Model: J10 Plus - Resolution: 4MP - Features: 100% Wireless - Connection Method: Wi-Fi - Sensor: PIR Sensor - Compatibility: Android compatible
