Hi Joseph,
How an institution manages 24 hour coverage depends on a few factors, like facility size and whether you have a guard tour system; if museum staff are allowed in after hours; how access and fire systems are managed; what sort of fire detection/suppression system is in place; if there are controls to ensure the guard is awake, alive, and safe; etc. I'd be happy to follow-up with you with advice tailored to your specific institution.
