About

DJOLT

Features
Read full description

DJOLT is built for the maritime, cruise, and yachting industries but adapts seamlessly to a variety of onshore settings. Designed to deliver high-priority alerts directly to your device within a local network, DJOLT eliminates the need for uninterrupted internet access, ensuring reliability in environments where connectivity may be limited. DJOLT operates with a locally installed DJOLT Server, using Local Push Connectivity, to ensure alert delivery even if the app is closed or running in the background. Supported Features: - View active and historical alerts, with timestamps for received and acknowledged alerts. - Acknowledge alerts within the app or by long-pressing a banner notification. - On/Off Duty setting to manage availability. - Critical Alerts that bypass Silent Mode, preventing missed notifications for high-priority situations. - Acknowledge and silence an alert for all recipients when acknowledged by a single user. - Adjustable alert volume. - Test notifications for setup verification. While optimized for maritime use, DJOLT’s on-premises functionality makes it equally effective for industrial facilities, manufacturing plants, and security systems, supporting reliable oversight and timely response to critical situations.
