A few months ago it was 98 degrees here (first time ever) and I noticed that the security floodlights on my house did not turn on when I walked by.
I think they are infrared and therefore would not turn on since the air temperature was as high as body temperature (I guess).
Anybody have experience with these?
BTW - the palm trees are still not in the water but temp is definitely rising

The lights are motion detectors not heat seeking missile guidance systems.

I think that just about all motion activated lights are infrared heat sensing. It says it on the product description that may not work if air temp is
at 99 degrees.
That's why I'm curious about anyone living in a desert area if there are alternatives beside a smart dog.

Being the giver that I am, I volunteer to observe the "hot chick" walk by and report back to the board of my findings.

I have personally noticed that heat-seeking moisture missiles don't work well when too hot and/or humid, but in extreme cold, FUGGETABOUDIT.

My lights over the garage door come on when I walk by and did so last summer when it was pretty hot.

There are several types of motion sensors.
