Проект заднего двора

　　Alex’s backyard is relatively large. Sometimes people break into his yard at night and lie on a chair to rest, but Alex doesn’t like others to disturb his life, so if you want to install a camera, it is best to have a colorful picture at night. LS-4GS12 is equipped with a white light. After turning on the white light, there is a colorful picture at night.
