It seems the floodlight camera does need to be connected to power in order to set it up. In my amateur experience with a dozen years of home Wi-Fi, 50 feet is a long distance for a clear Wi-Fi signal through a residential structure. Our farthest camera is about 25 feet from the nearest wired Wi-Fi access point, and that access point has a high-gain directional antenna to ensure a good signal with the camera. All our other Google Nest devices are within 3-15 feet of a wired access point.
On another thread yesterday (https://www.googlenestcommunity.com/t5/Cameras-and-Doorbells/Wired-floodlight-camera-not-connecting-...), the customer is having trouble connecting their floodlight camera at 27 feet. Google Nest Support suggested that the customer purchase one of the charging cables used for the Google Nest Camera (Battery) (we have this camera; it's basically the same as the floodlight camera), so they could temporarily plug their floodlight camera into power close to their router/modem in order to initially connect to Wi-Fi. But even if they succeed, there's no guarantee that when they move the camera back to its permanent location 27 feet away that it will be able to maintain the Wi-Fi signal at that distance.
