Camry Intrusion Alarm Triggers When Car Parked Outside in 75 degree+ Conditions

[Ibhipru]

Does anyone have an idea as to why my alarm goes off randomly when the car is parked in the sun on a warm to hot day.  I either have to turn the alarm off by pressing the open door button on the FOB or sometimes the alarm will stop by itself after about a minute.  However, the alarm will trigger again about an hour later.  My wife swears the alarm will go ff even if the doors are unlocked but I don't see that as possible as the alarm doesn't set until the doors are locked.  My initial theory was it was due to the hood latch sensor but yesterday the car was parked in covered parking with only the trunk area exposed to the direct sun (the temperature was about 90).  Is there a fuse I can pull to deactivate the alarm system?  I have a 2019 Camry and the alarm was factory installed.  Any help would be appreciated.
