ARMY Client — Security Monitoring

Product Engineer

Available on:

When you entrust the security of your office building or business property to a security service provider, how do you know they are actually performing their duties properly? What if an emergency occurs in the middle of the night?

ARMY Client is a mobile application developed for PT Agung Rahardja Manunggal Yudha (ARMY) — a professional security service company. This app provides full transparency to corporate clients to monitor security activities at their properties.

With ARMY Client, business owners and facility managers can view real-time patrol history, ensure guard schedules match their contract, and most importantly — press a panic button to call for emergency assistance anytime, anywhere.

This application bridges the communication between clients and the security team, transforming the relationship from "blind trust" into a transparent and measurable partnership.

Developed in collaboration with Art By Code (ABC), an IT consulting company.

Problem → Solution → Impact

Problem

Business owners have no visibility into whether security guards are actually performing patrols according to schedule.

When emergencies occur (theft, fire, suspicious individuals), there is no quick way to call for help — relying on phone calls or WhatsApp that may not be answered immediately.

Communication with security providers is still manual and undocumented, making it difficult to track accountability.

Clients must "blindly trust" without concrete evidence of security activities at their premises.

Solution

Built a mobile application that allows clients to view complete patrol history with timestamps, photos, and GPS locations.

Implemented a one-touch panic button that instantly sends alerts to all security personnel with automatic GPS location — ensuring help arrives in seconds, not minutes.

Created a transparent guard schedule dashboard showing who is on duty, when shifts change, and real-time attendance status.

Integrated real-time push notifications for security updates, patrol completions, and emergency alerts.

Impact

Clients gain peace of mind with full visibility into security operations at their properties
Emergency response time reduced from minutes to seconds with the panic button feature
Client-security relationship becomes more professional and measurable with documented activities
Disputes reduced significantly as all patrol activities are timestamped and recorded with evidence
Business owners can monitor security remotely 24/7 from anywhere via their mobile device

Engineering Challenges & Solutions

Technical obstacles encountered during development and the architectural decisions made to overcome them.

Challenge

Panic alerts must arrive within seconds, even when the app is in background or device is locked

Solution

Implemented Firebase Cloud Messaging with high-priority data messages and Android foreground service with custom alarm sound. The notification system bypasses battery optimization to ensure critical alerts are never delayed or silenced.

Challenge

GPS location must be accurate when panic button is pressed for effective emergency response

Solution

Integrated OpenStreetMap with real-time location services. The app continuously tracks location in the background and captures precise coordinates at the moment of panic, including the option to select specific building or outdoor location for better context.

Challenge

App must remain responsive even with unstable internet connectivity common in building basements and parking areas

Solution

Built offline-first architecture with local storage using GetStorage. Critical data is cached locally and automatically synced when connection is restored, ensuring the app remains functional in low-connectivity areas.

Challenge

Feature updates and critical bug fixes need to reach users immediately without waiting for Play Store review

Solution

Integrated Shorebird for over-the-air (OTA) updates, enabling instant deployment of patches and new features. Critical security fixes can be pushed to all users within minutes instead of days.

Architecture Overview

ARMY Client follows a modular architecture with GetX for state management, routing, and dependency injection. The app communicates with Firebase services for real-time notifications and crash reporting, while business data flows through REST API to the backend. Local storage ensures offline capability for essential features.
