Actually I had the heat consideration yesterday after swapping in the 
‘updated’ RPi SD Card – the one using Motion 4.3.2. Used a non-contact 
detector from about 12’ ( 4m) away and 91°F (33°C) late afternoon – Sun 
not hitting the window; measured just now (8:30 a.m.) and 85°F (29°C) 
–currently overcast and so not ‘glaringly bright’. Minor occasional 
glitches (I’ll accept those!). (Another camera on a different Pi looks 
at a white vinyl-sided house and never a glitch.)


The window (and so cameras) face East, so the heat and Sun could be 
suspect.


The cameras are SV-USBFHD06H-BL36, which appear to be the equivalent of 
ELP-USBFHD06H-BL36. (I’ve forgotten how I made this conclusion.) The ELP 
specifications list: Working temperature

-10～70℃ (storage -20～85℃) – so 14-158°F.


Elevation shouldn’t be an issue, though we have joked about about 
climbing up here to the second floor. :) Google lists the city as 571’ – 
so nowhere near the approximately mile you suggested.


You asked about if some of the cameras are hotter than others. There are 
two SV (the brand) cameras cameras in the window – about a foot apart 
and should be ‘twins’ as same model and purchased together. Both have 
glitch issues, just one much more than the other. Currently “Camera 1” 
is occasionally glitching while “Camera 2” is not; yesterday afternoon 
and evening Camera 2 was glitching like mad. No overnight boot/resets. 
The only change I can think of is the date


Thanks for the suggestions!
