Microphone and Speaker: Sometimes just having a camera isnât enough. Sometimes you need to communicate with someone whoâs on the other end, but they donât necessarily have their phone on them, or maybe they donât have a phone at all. An example might by you see someone running with scissors, so you need to tell them not to run with scissors. Or maybe youâre trying to guide someone through a cooking recipe. Either way, itâs probably a safe bet to get CCTV panoramic cameras that have a two-way speaker.
