Thank you for viewing. I purchased this item new about six months ago and installed it indoors. There are no issues with its operation. At night, a white light automatically turns on when someone approaches. By downloading and registering the app (see the 5th photo), you can check real-time images on your phone and also control the camera to check the surroundings. You can also record and save footage by inserting an SD card. Please refer to the included instruction manual for setup, registration, and installation. In these uncertain times, a security camera is an essential item. If you are already using the app (5th photo), how about adding this as an additional camera? ・Used item, so no guarantee, no claims, no returns (3N). ・All images are included. ・SD card not included. ・No price negotiations. Thank you for your understanding. Please consider purchasing if you agree to the above.
