PoE cameras do not need a separate power source CCTV CamerasĪnalog footage to a monitor or recorder via coaxial cableĭigital footage to an NVR via wifi or ethernet cable While the systems serve the same function-surveillance of strategic areas-they are different in some key ways. It is only converted if it’s sent to a digital video recorder. The video footage captured is analog and typically lacks audio. CCTV Cameras in a NutshellĪs mentioned above, a CCTV camera is part of a closed circuit that includes a camera, television monitor, and possibly either a VCR or DVR for recording and storage.Įach camera needs its own power source-battery or outlet-and must be connected to the monitor and/or recorder by a physical coaxial cable. So an IP camera can be wireless or PoE, but they both send already-converted digital data to a network video recorder for storage. This is called power-over-ethernet (PoE). Those connected to an NVR by ethernet cable receive power that way. Wireless IP cameras need their own power source, either a battery or a nearby electrical outlet. The digital footage is then sent to a network video recorder (NVR) either wirelessly via a Wi-Fi signal or by ethernet cable. IP Cameras in a NutshellĪn internet protocol camera is a video camera that captures footage and converts it into digital format within the camera itself. IP CamerasĬCTV cameras must be connected to a monitor or recorder via a physical cable. At the opposite end of that spectrum, internet protocol (IP) cameras transfer the video footage wirelessly via a Wi-Fi signal. That can be a blessing and a curse, but that’s the fundamental difference between a CCTV and an IP camera. They’re better than nothing, but you’re not doing yourself any favors by investing time and money into them.īut CCTV isn’t your only option. You’ll likely only encounter CCTV systems equipped with a VCR at pawn shops, flea markets, and yard sales.
