I purchased several $20 home wifi cameras and one $30 pan & tilt wifi camera from wyze .com because of the low cost, high quality, ese of use, and the many features. It can alert you if a smoke or carbon monoxide alarm goes off, offers person detection, has night vision and 2-way audio. The company also sells LED wifi bulbs, wifi smart plugs, contact and motion detectors. So as to best? For my needs and budget it is the best; however, your smileage may vary, so look for reviews and ratings.
