Sentry Freedom includes the same great features that our hard-wired system provides, with the added benefits of a wireless solution. Heritage MedCall integrated the best available technology, we chose Inovonics 900 MHz spread spectrum technology as the back bone of our wireless system and Dell Computers for our master console. Partnering with companies who have solid reputations and proven products helps to ensure that our customers will be using the best solution available.
