We are working on a project where CCTV equipment is being installed in controller cabinets, and have expressed concern over whether the equipment will cope with the heat. The supplier assures us it will be ok, but we’re still apprehensive as the stated operating temperature for the hardware is only 40C.
I understand you cannot put the supplier name on the forum, but could you tell me whose equipment you have. My email details are in my profile.
As for cooling cabinets, this used to be a problem with some controllers back in the early 80’s. One particular type of controller (from a now defunct supplier) used to regularly be painted white to attempt to keep it cool. This helped, but was of limited success.
