Welcome to the Forum, @jacop_s!
I’ll start by saying that I don’t have any of Wyze’s floodlight cameras, but I think this is an interesting question, and I’m curious to see what Forum members with some of the Wyze Cam Floodlight models might suggest.
Since you already have motion sensors separate from your floodlights, then what would prevent just installing something like a Wyze Cam OG or Cam v4 near your motion sensors? That seems like it’d potentially be the easiest solution, assuming that your current sensor/lighting setup works as intended.
If, however, you’re looking specifically for a camera’s motion detection to trigger a light, then I imagine you could replace your motion sensors with small Wyze cameras (again, Cam OG or Cam v4 is what I’m thinking), install a Cam Floodlight model in place of your current floodlight, and then use Automations within the Wyze app to trigger the light (e.g., if a Cam OG detects motion, then turn on the Cam Floodlight’s light for a certain amount of time). Here I want to be clear that, since I don’t own any Wyze floodlights, I think this kind of Automation Action is possible based on what I’ve read in the Forum, but I’m not 100% positive.
Doing this second option (assuming the Automation Action exists as I think it does) would be more expensive and require more work, but it would also give you an additional camera for coverage from a high vantage point. If you just want lower-level camera coverage and your motion sensors and floodlights are currently working as expected, then I’d probably colocate Cam OGs with Outdoor Power Adapters near the motion sensors and call it good. Depending on your sun exposure, climate, and weather conditions at the mounting location, I might also consider protective hoods or enclosures for the cameras, either third-party solutions or DIY, possibly even 3D-printed covers, depending on your application.
Edit: A third option occurred to me. If you already have a switch (like a regular light switch) in the circuit controlling power to your floodlights, then you could potentially replace that with a Wyze Switch, which would give you some automation options, such as if a camera detects motion, then that could turn on power to your existing floodlight.
I think you might have several options here, and I’m interested in learning what others might suggest.
