NMT Eclectic
Full-Scale Modular IoT Home Automation Solution
Eclectic is a proposed smart home automation platform currently under development at NMT Electronics. The concept brings several existing NMT product lines, such as Sentry and Photon, under a single unified platform, replacing the need to manage each device independently through separate interfaces. Rather than building from scratch, Eclectic is designed to evolve from a proven foundation: the real-world experience gained from deploying and iterating on these earlier products directly informs the architecture, priorities, and design decisions of the new platform.
Integration Architecture
The foundation of Eclectic is a consolidated system: a cohesive and coordinated platform. Automation routines, device states, and system responses are managed through similar control layers, ensuring consistent behavior. This unified approach reduces configuration complexity for the end user while giving the system a clearer picture of the home environment as a whole, enabling smarter, more context-aware automation decisions. The platform is designed with modularity in mind: subsystems can be added, removed, or upgraded independently without disrupting the overall system.
Modernization and Expanded Capabilities
Eclectic represent a technical leap forward compared to the individual products it succeeds. The platform is built around more advanced radio modules and full IoT connectivity, enabling remote access, cloud integration, and reliable inter-device communication. Security is handled at the system level rather than per device, extending capabilities with consolidated encryption, coordinated device responses, and a more robust user control. The platform also expands on sensing coverage and introduces advanced powering options, making it suitable for a wider range of installation environments and use cases.
User Interface and Control
Devices in the Eclectic family are intended to provide a unified control experience across all connected subsystems, accessible through unified application interfaces. Users will be able to configure automation routines, monitor system status, and respond to alerts from a single point of access, without switching between separate applications for each device.
Development Status
Eclectic is currently in the proposed and active development phase. Specifications, supported integrations, and feature scope are subject to refinement as the platform progresses. Further updates will be published as development advances.

The module is available in three connectivity configurations: WiFi and BLE, ZigBee, or standard 433 MHz, covering a broad range of integration scenarios within the Eclectic ecosystem and beyond. It is designed for straightforward installation with modern powering in mind, featuring USB-C connectivity and an integrated rechargeable battery for flexible deployment across various indoor environments.
NMT Sentry Gen 2
Wireless Indoor Home Security System
Sentry Gen 2 is the second generation of NMT Electronics' home intruder alarm platform, currently in the design phase. It is a substantial evolution from Gen 1, addressing the limitations of the earlier system with a modernized architecture, significantly improved security, and a more flexible hardware platform. The same proven concept of a distributed, fail-safe multi-node alarm network is retained, but rebuilt to a considerably higher standard across all dimensions.
System Architecture and Modularity
Gen 2 maintains the Central and Surveillance node model, but introduces a higher degree of modularity compared to its predecessor. The product family includes dedicated node variants: Central, PIR, ultrasonic, and microwave; all sharing a unified enclosure design for a consistent and professional installation appearance. Each node is capable of operating independently, while also participating in a coordinated network when deployed as part of a larger system, giving the installer greater flexibility in how the system is scaled and configured.
Authentication and Access Control
Physical key operation, carried over from Gen 1, is now optional. Gen 2 introduces RFID-based authentication and digital device access with high-end encryption, replacing the basic physical security model of the first generation with a more robust and modern access control framework suitable for professional installations.
Connectivity
Wireless communication is upgraded from the simple 433 MHz ciphering used in Gen 1 to industry-standard WiFi and BLE modules, providing a substantially more secure and capable communication backbone. Standard 433 MHz wireless and wired connectivity remain available as fallback options, ensuring installation flexibility across environments where WiFi infrastructure may be limited or unavailable.
Processing, Power, and Design
Gen 2 is built around modern processing and powering hardware, reflecting the current state of embedded systems development. The overall industrial design is significantly more refined compared to Gen 1, with a portable and modular form factor intended for clean, professional deployment in residential and light commercial environments.
Development Status
Sentry Gen 2 is currently in the design and prototyping phase. Specifications, configurations, and features are subject to refinement as development progresses. Further updates will be published as the platform advances toward prototyping.
Surveillance Node
Our tiny surveillance node is only the size of a quarter, but it's packed with technology that automatically senses the presence of humans. It relays that information to our monitoring nodes, which are also equipped with cameras and microphones. We can then send that information to you via email or text message. The node also allows us to report faults or alerts when other connected devices fail - like when your front door opens unexpectedly at 2am.
Central Node
The Monitoring Node is the central brain of your surveillance network. It acts as a coordinator for all of your other nodes: sending and receiving data, reporting and logging status, and monitoring other nodes in the network. It can also interface with more complex loads like large sirens and lights.

NMT Hydra Gen 1
Household Water Monitoring and Management System
Hydra is a water tank monitoring and control system developed by NMT Electronics. The device is designed to mount directly onto any water tank, whether metal or plastic, with minimal invasion to the existing installation. Rather than requiring complex plumbing modifications, Hydra is built around the principle of non-intrusive deployment, making it practical for residential and light commercial environments alike.
Sensing and Control Architecture
Hydra integrates two complementary sensing technologies into a single unit: resistive-based water level detection and ultrasonic ranging, providing reliable level readings across varying tank geometries and materials. Each monitoring module can operate independently, directly driving a dedicated pump driver module based on configurable level thresholds and schedules. For installations with multiple tanks, modules can alternatively operate in conjunction with a central control and monitoring node, which serves as an IoT gateway for the entire system, enabling coordinated management and remote oversight across all connected units.
Connectivity and Installation
The monitoring module is housed in a robust enclosure designed for permanent outdoor installation, with provisions for cable routing and antenna clearance. Connectivity is available in two configurations depending on installation range and environment: 433 MHz wireless via an integrated helical antenna, or wired communication over standard CAT6 cable through onboard RJ45 ports. Repeater support is available for extended coverage across larger premises.
Development Status
Hydra has completed initial prototyping and is currently in the development and testing phase. Specifications and supported configurations are subject to refinement as the platform progresses toward release.
Monitoring Module
The Hydra monitoring module is the core sensing unit of the Hydra system, designed for direct mounting onto the water tank. It houses the resistive and ultrasonic sensing elements, the pump control interface, and the communication hardware within a compact, robust enclosure built for permanent outdoor exposure. The module features an integrated helical antenna for 433 MHz wireless operation, onboard RJ45 ports for CAT6 wired connectivity, and a set of status indicators for local diagnostics. Depending on the installation configuration, the module can operate as a standalone unit with direct pump control, or as a node within a larger multi-tank system managed through a central Hydra control node.

NMT Sentry Gen 1
Wireless Indoor Home Security System
Sentry Gen 1 is NMT Electronics' first-generation home intruder alarm system, and the first product ever released under the brand. Developed across three successive hardware iterations, X1, X2, and X3, it established the foundational architecture that the Sentry series continues to build upon. Despite its simplicity, the system proved itself through successful real-world installations, validating the core design approach of a distributed, fail-safe alarm network. Gen 1 is generally discontinued in favor of the second generation, which offers significantly more modern features, robustness, and sophistication.
System Architecture
The system is typically composed of at least two node types: Surveillance and Central. Surveillance nodes serve as terminal sensing points distributed across the protected space, each capable of detecting intruder presence and communicating alerts to the rest of the network. The Central node coordinates all connected Surveillance nodes and can interface with large external loads, such as powerful siren alarms or main lighting circuits. Nodes communicate over an independent wireless indoor network with basic ciphering, and both node types are operated using physical keys.
Sensing and Hardware Options
Each iteration of Gen 1 supports one of three selectable sensor configurations: directional ultrasonic sensors, non-directional passive motion sensors, or millimeter-wave radar, allowing the system to be matched to different environment types and detection requirements. Surveillance nodes include a local buzzer alarm, an LED status interface, and a DC-powered rechargeable battery backup, ensuring continued operation even in the event of a deliberate power cut.
Production Status
Sentry Gen 1 has been successfully installed and field-validated, and is considered a proven baseline for the Sentry product line. It is generally discontinued and no longer in active development, with NMT Electronics directing new deployments toward the second generation platform.
