Replacing an existing floodlight, on the other hand, is surprisingly simple. We swapped out the dumb floodlight on our back patio with the Floodlight Cam in a little over 30 minutes. Here are the basic steps: First, shut off power to your existing floodlight at the breaker, remove the current light from the junction box, and disconnect the wires. Next, you'll need to install the included mounting bracket and run the disconnected wires through the center of it. Ring provides a convenient hook with the Floodlight Cam, and you can use it to hang the unit from the bracket while you reconnect its ground, neutral, and hot wires.
