DUO™ IP/LTE Dual-Path Security Module For DSC/Honeywell Panels

Dual-Path Control

The DUO™ IP/LTE is a full DUAL-PATH solution in one form factor. It is a powerful TCP-IP and/or LTE based bus-level interface to DSC PowerSeries* panels and Honeywell Vista* panels. It allows you to view the status of and even control your alarm panel through a standard web-browser or smart-phone. The DUO™ also supports a special Stand-Alone mode that allows it to form the base of a customizable full security system on its own.

EyezOn LTE Service

A subscription to the EyezOn LTE service as well as a qualifying base service is required for the DUO to operate in LTE mode. The DUO will operate like an EnvisaLink without a subcription. You can pick from either the EnvisAlarm Monitoring Service or Envisalerts Plus Service and add the EyezOn LTE service for only $4 per month on top of the base service cost. SIM is included.*

EnvisAlerts Service

With the addition of the EnvisAlerts service your control is enhanced and can be extended to anywhere in the world. EnvisAlerts also allows you to specify e-mail or SMS addresses to receive alarms, arms, disarms and more.

With the EnvisAlerts Service

With EnvisAlarm Service (Optional)

Plays Well With Others
