Micro cameras can be easily installed without tools by finding an unobstructed area to place the camera, positioning the lens to view the desired area, and connecting the wireless receiver to a TV. The receiver should be angled toward the camera with the power on to check picture quality. The camera's video cable is then connected to the receiver's output and the TV's input so pictures display on the TV when turned on. Placement may require adjusting the antenna if wireless interference occurs. Regulations restrict recording in certain private areas like bathrooms.
