This Sentinel PRO Monitoring System with Cellular Modem comes with a clear door enclosure and uses the AT&T cellular service. It helps to provide operating in locations where an Ethernet connection isn’t obtainable.
Packed with all the reliability you’d expect from a Sensaphone unit, it allows you to check the conditions of your climate-sensitive assets. These can be accessed remotely using the website and mobile app to check programming and status updates. It’ll monitor, deliver arms, and datalogs input/output points from third-party Modbus sensors, transducers and programmable logic controllers. Notifications can be sent to your smartphone in the form of an email, text or a phone call.
It comes with a clear door NEMA-4X rated enclosure, which is recommended when installing the Sentinel in dirty, humid and unsecure environments. The Sentinel Pro’s basic ethernet cloud package is FREE so you don’t have to worry about monthly payments. A Premium Ethernet subscription is available at a cost.
