All good points, thank you.We get your need for imminently, but don't let that take you down a path that will cause buying new cameras in 6 months.
Stick to the cameras on the ideal MP/sensor ratio.
As others have said, these are not floodlights. These white LEDs are not much brighter than a few cell phone flashlights - looks bright looking right at them, but they do not light up an area very much. They are gimmicky and won't scare anyone away, not even wildlife.
Motion activated lights are not a deterrent. There are enough videos here showing that perps do not flinch when a floodlight turns on. They avoid homes all lit up, so go with floodlights on all night.
Watch this video someone posted and how the floodlight comes on and they don't even flinch. But then the audio comes on and they don't know which way to run LOL.
Either keep the lights on all night or not at all to ensure the best chance of capture as some cameras can be temporarily blinded when the spotlight kicks on and you lose the ideal captuer.
However one of them is going directly below her bedroom window on the second floor. She doesn't want a constant light, and she likes to sleep with the window open on warm nights.
Mothers, amirite?
I know that the white LEDs are not meant to light up an area, but if they are enough to give the camera enough light to capture decent night colour footage when detecting a person 9ft away, would the 1/2.7" be enough?
