On October 14, 2025, Callan JMB Inc. announced the launch of Sentry 4.0, the latest version of its proprietary Sentry Monitoring System. The new release expands the system’s accessibility by moving from a Java‑based platform to an HTML5 interface, allowing users to monitor refrigerator, freezer, and clean‑room temperatures from any device with a web browser.
Sentry 4.0 retains the core features of its predecessor—24/7 active monitoring, real‑time alarm notifications, and compliant reporting data—while adding mobile‑friendly access. The upgrade enables customers to view monitoring data and manage alarms from PCs, Macs, iPhones, Android phones, or tablets without downloading additional software, thereby improving operational flexibility for pharmacies, hospitals, and emergency preparedness facilities.
By enhancing user experience and broadening device compatibility, the upgrade positions Callan JMB to better serve its existing client base and attract new customers seeking reliable, mobile‑friendly temperature monitoring solutions. The move strengthens the company’s technological moat and supports its strategy of delivering a “Gold Standard” client experience in the life‑sciences logistics sector.
