Cut AI Costs by 90%: Why Smart Companies are Downsizing to Small Language Models (SLMs)
Engineered for high-risk field workers, this connected worker safety platform uses custom IoT device telemetry middleware for EV-04 hardware. By pairing self-hosted tracking engines with global Emnify eSIM profiles, it delivers zero-latency SOS alerts and automated emergency response.
Landmark Security partnered with Mindster to build EbanAlert, a custom lone worker safety platform for heavy industrial sectors across Africa, such as mining and energy. In off-grid environments where standard networks fail, emergency delays create major operational risks. To eliminate third-party SaaS fees and secure telemetry pipelines, Landmark Security needed a self-hosted IoT location tracking engine for EV-04 hardware
The Challenges
Deploying lone worker monitoring software in remote industrial zones presented major architectural hurdles. Landmark Security faced unreliable off-grid connectivity, data vulnerability, high monthly SaaS fees from third-party aggregators, and complex global logistics across international borders.
Build a self-hosted IoT telemetry middleware to decrypt raw TCP/UDP data streams directly from EV-04 tracking hardware, bypassing third-party IoT aggregators and eliminating ongoing vendor lock-in.
Interpret high-sensitivity 3D G-sensor data in real time to capture fall-down events and route immediate SOS alerts—complete with precise GPS coordinates—to emergency dispatch teams in under 10 seconds.
Automate global supply chain workflows by connecting subscription e-commerce checkouts directly to DHL fulfillment APIs, enabling friction-free dropshipping from manufacturing sites straight to field teams.
Eliminate cross-border network drops by integrating Emnify eSIM profiles directly into the platform, driving dynamic over-the-air carrier switching based on real-time signal strength without physical SIM changes.
Engineer multi-tenant role-based web and mobile applications tailored for four distinct user groups: corporate fleet managers, system administrators, field executives, and Regional Rapid Response Teams.
Remove volatile per-device monthly SaaS fees and eliminate data exposure risks by moving away from external IoT parsing vendors to an independent, enterprise-owned cloud data pipeline.
CLIENT REQUIREMENTS
The client didn’t just need an app; they needed a workflow transformation that could sit between their core ERP and the physical retail floor. The primary requirements were:
A mandate to eliminate physical invoice handovers and transition to a 100% digital “E-Invoice” workflow.
A system that could “grab” data from the ERP and instantly alert the packing and delivery teams the moment a payment was confirmed.
Moving away from verbal updates to automated WhatsApp and SMS notifications, providing customers with a “soft copy” of their invoice and live status alerts.
A way to manage customer flow using digital tokens that could be assigned, tracked, and reused across different retail outlets.
THE SOLUTION
Mindster engineered a self-hosted IoT safety ecosystem for Landmark Security. By deploying custom TCP/UDP middleware to parse raw EV-04 hardware signals, integrating Emnify global eSIM profiles for dynamic roaming, and automating DHL drop-shipping pipelines, we delivered a secure, zero-latency lone worker safety platform.

ARCHITECTURE OVERVIEW
To guarantee high-throughput processing and zero-latency safety alerts, Mindster engineered a four-tier cloud architecture for EbanAlert. The ecosystem seamlessly bridges EV-04 wearable hardware with custom TCP/UDP telemetry parsers, third-party global APIs, and role-based operational web and mobile dashboards.

FAQ'S
By cutting out middleman aggregators entirely. Mindster built a custom TCP/UDP middleware engine that sits on a private, self-hosted cloud. This backend directly ingests raw, byte-level hex packets coming off the EV-04 wearables, decodes the telemetry in-house, and routes it straight to user dashboards—saving thousands in recurring per-device license costs while protecting data privacy.
Under 10 seconds, end to end. The moment a worker’s 3D G-sensor detects a heavy impact or an SOS button is pressed, the raw signal hits the parsing middleware. Combined with Emnify’s low-latency eSIM network, live spatial coordinates instantly pop up on dispatcher maps without waiting for batched cloud updates.
It uses embedded over-the-air (OTA) Emnify eSIM profiles. Instead of locking a device to a single mobile provider, the tracker automatically assesses local signal strength and hops to whatever cellular operator offers the strongest link. No manual carrier changes, no physical SIM swaps, just borderless coverage even in high-risk, remote fields.
Yes. The platform hooks directly into DHL Express APIs. When an enterprise client buys or renews a subscription through the e-commerce checkout, the system automatically triggers a shipping order, drafts waybills, handles customs paperwork, and ships pre-configured hardware straight to field teams anywhere in the world.
Landmark Security owns 100% of it. Because the architecture doesn't rely on third-party IoT parsing vendors, every piece of real-time GPS positioning, fall detection data, and historical user logging stays locked inside the client’s private cloud environment.
