The Sensaphone Sentinel is a brand new Sensaphone alarm. The next step in remote monitoring solutions from Sensaphone the Sentinel provides users with access to sensors readings remotely via a web-based interface. The Sentinel has 12 distinct inputs for monitoring up to 12 different conditions/alarm sensors and can store an unlimited number of data logged records for each sensor. When alarm conditions for any sensor are recognized users are instantly alerted via e-mail, telephone or text message*. For remote locations the Sentinel is also available with a built in cellular modem, so no hard wired internet connection required! For Installers/Integrators: The Sentinel is the first web based Sensaphone alarm that allows multiple devices to be registered under the same online account. Now you can easily manage and monitor all of your clients and their devices through a single account, no more having to keep track of different accounts for each client! The Sentinel is also a "supervised" system, meaning if there is a disruption in service causing the Sentinel to lose its connection with the servers users will be alerted right away! *Text message and phone call notifications only available with paid subscription
