iDefender is the Fracarro app dedicated to users who want to manage their own anti-theft system either locally or remotely in a simple and intuitive way. Using the optional module MOD-LAN or MOD-LAN EVO, the app allows you to control all DEFENDER control panels via the new FRACARRO CLOUD, with every internet provider and without requiring changes to your router configuration. Thanks to iDefender and Fracarro Cloud, you can arm and disarm your security system either totally or partially, as Master or custom user. You can also view the event log and activate/deactivate your control panel outputs to enable home automation functions. With the new alarm video verification you can now also receive video notifications from your security system to verify what caused an alarm. New features require DEFENDER Ver 2.9 / DEFENDER HYBRID Ver 4.4 and MOD-LAN / MOD-LAN EVO Ver 3.0 or more recent versions.
