Epoxy sealed thermal switches prevent cameras from overheating in hot and humid conditions. Wrapped in protective epoxy, these switches smartly regulate temperature, kicking in cooling mechanisms when needed. Designed with outdoor settings in mind, these thermal switches not only extend the life of cameras but also shield them from moisture, allowing them to deliver top-notch performance regardless of the environment.

State correctional facilities have multiple cameras installed on the exterior of their buildings.  These cameras are installed with heating and fan systems to maintain the temperature in the operating range, which is where our thermal switches come in to prevent overheating or freezing.

Thermal Switches Prevent Cameras from Overheating

Both the heating unit and the fan unit use a 240VAC supply from the thermostat.  A couple of different mounting styles are used for the different units.  The 2570 sealed thermostat works well in this application as it can handle the moisture and the outdoor environment well. Our temperature switches work by using a bimetal disc. The bimetal disc in the switch reacts to heat, and opens or closes a set of contacts based on what the ambient temperature is. This is works because the different metals in the disc react to heat in different ways, which causes the disc to bend.
