Although the Swann 4K PoE system was the most expensive on this list at $1,080, it was well worth it. That’s because it’s also the only one with artificial intelligence capable of person detection and facial recognition with no subscriptions required. With person detection, the cameras alerted us if there was a person in view. The one we placed above our apartment’s front door, in particular, helped us stay in the know if there was someone at our door. With facial recognition, the cameras put a name on the faces it saw, with our help, of course. We uploaded our faces to the NVR under Advanced Analytics and after that, the cameras were able to tell if we were in the frame. But that’s not the best part. The NVR software allowed for tons of customizations. For instance, when an underaged cousin stayed with us, we set one of the cameras to alert us if he’s seen anywhere near where we hid our liquor, while the rest simply ignored him. Not on our watch, Brian., Power over Ethernet (PoE) security cameras combine the ease-of-setup of wireless cameras with the reliability of wired cameras. Typically, PoE cameras connect to a DVR or NVR for local storage, but there are some that connect to a router to send and store videos in the cloud., PoE (Power over Ethernet) security camera systems are a reliable choice for both home and business monitoring. These wired security camera systems use Internet Protocol (IP) cameras with PoE.
