Floodlight cam wired plus - motion sensor lights

I have a security camera in the garden and I’ve had to turn the motion activated lights off as basically they just constantly keep coming on. I can see lots of bugs zipping past the camera but surely they are calibrated for that? It’s not setting the motion alerts off, just activating the lights. Any ideas? I have disabled the feature at the moment but then when we do go in the garden at night/if motion is detected we don’t get the security light!
