NVR Max Ambient Operating Temps

I'm considering installing the NVR unit in a spare storage room that can reach about 100 F or so during hot months of the year. Would this be a concern for the NVR unit?

I found this specification for the NVR unit: "Working temperature -10℃~+55℃(14°F~131°F)"

I assume that this is not referring to ambient temperature, is it?

Hi Steampunk,
-10-55 ℃ is for its ambient temperature to operate. Thanks.
