You can connect a wired IP camera to your current wiring or a socket. It's always powered that way, so you never miss what happens. There are wired cameras for indoors and outdoors. You can connect the camera to WiFi or to your router via a network cable. A security camera with Power over Ethernet receives internet and power via 1 cable. Keep in mind that you need a socket outdoors or drill a hole to power your camera, if you choose a wired outdoor camera.
