1. A thermal monitoring system for monitoring for vacuum failure in a cryogenic storage container, the thermal monitoring system comprising comprising:
a cryogenic storage container comprising an external wall and an internal wall, wherein a cold cryogenic liquid is housed within the internal wall, and wherein a vacuum is formed between the external wall and the internal wall;
a thermal imaging camera configured to measure temperatures within a region of interest, wherein the cryogenic storage container is oriented within the region of interest and the thermal imaging camera measures an external temperature of the outer wall of the cryogenic storage container, the thermal imaging camera further comprising camera software configured to generate a thermographic video of the external temperature;
a display device displaying the thermographic video; and
an alarm unit configured to activate an alert when the external temperature of the cryogenic storage container drops below a pre-selected trigger temperature indicative of a vacuum failure of the cryogenic storage container.
