Yes, someone may plug an smart phone to the usb for charging. Those ports now include the ir diodes (repositioned, same included in the V3). I normally plug the outlet cam while staying a couple of days out of town. Wyze is not the best if considering the 5 minutes cool down period. But within a closed environment, like my living room, receiving a notification could means trouble. The mic/spk are the ones included with the camera
thanks Mike A, I included a 32GB SD card. Mostly intrested in receiving a notification if motion is detected. As mentioned, I only plugged when I know no one is home
