Normally open(NO) and Normally closed (NC) are terms used to define the states that switches, sensors or relay contacts are under when they are not activated.
A NO contact or a normally open contact is the one that remains open until a certain condition is satisfied such as a button being pressed or some other manner of activation such as those based on temperature, pressure, etc.
A NC contact or normally closed contact is the exact opposite of NO contact by function. It remains closed until a certain condition is satisfied.
Lighting control cabinets typically control a group of street lights or advertising signage from a "control cabinet". These controls have historically provided on-off functionality based on the time of day using an "astronomical clock"-based switch or daylight photosensor. Lights are controlled in groups with no individual control over a specific light.
Although new controllers such as Tondo's Edge-IQ controller have replaced the cabinet-based approach with new technologies that include advanced dimming, remote cloud-control, and support for functionality including sensors and switches, there are many outdoor lights and signs that do not support on-lamp control. Tondo's Cabinet-IQ controller provides new advanced IoT technology support for existing cabinet-controlled lighting.
CAT-M/LTE-M and NB-IoT are similar but have differences that may make one suitable over another, or simply selected based on the support for one or the other that is available in your area.
NB-IoT uses a narrow bandwidth of 200 kHz, where CAT-M uses 1.4 MHz. The maximum data rate for NB-IoT is ~ 250 kb per second, with CAT-M1 reaching ~ 1 Mbps. CAT-M is marginally less energy efficient than NB-IoT. Although NB-IoT has a lower speed, both NB-IoT and CAT-M are suitable for sensor communications since sensors typically do not require much bandwidth.
Both NB-IoT and CAT-M1 are supported under the 5G technology specifications and therefore are ideal for selecting as a standard for sensor communications.
CAT-M wireless (aka LTE-M) is a low-power wide area network (LPWAN) cellular data transmission standard that operates over the data and physical layer. CAT-M was designed for IoT projects, with an average upload speed between 200 kbps and 400 kbps.
Eddystone is an open-source Bluetooth advertising protocol originally designed by Google. It can be used by mobile device applications to deliver improved proximity-based experiences that include applications such as Google Maps.
These packets can be discovered with any Bluetooth LE APIs such as Core Bluetooth on iOS, or android.bluetooth.le on Android. You can also use them with Google’s Nearby Messages API, which can be integrated into an iOS or Android app, and receive “messages” in those apps when a person enters or exits a range of beacons.
Tondo's 2022 estimate was calculated for each lighting category by applying market growth factors for each lighting category between 2015 and 2021 based on U.S. Census data to the DOE dataset.

Zhaga Book 18 describes a smart interface between outdoor luminaires and sensing/ communication nodes.
Zhaga Book 18 allows any certified node to operate with any certified luminaire. Certified luminaires and sensing / communication modules are available from multiple suppliers, establishing an ecosystem of compatible products.
The NEMA ANSI C137.4-2021 builds on the NEMA C137.41 7-pin connector standard and the DALI communication protocol. It has additional characteristics and features that align very closely with the D4i family of specifications from the DALI Alliance.
D4i and ANSI C137.4-2021 specify the digital communication between luminaires and devices including sensors and network lighting controllers. The expanded ANSI C137.4-2021 now includes energy reporting data and diagnostics and maintenance data.
The NEMA ANSI C137.10 standard specifies roadway and area lighting equipment connector compatibility. The 3-pin standard does not provide for dimming control, but provides for on/off operation. The later standard C137.41 adds dimming control (5- and 7-pin connectors) and sensor control (7-pin connectors). The newer C137.4-2021 standard provides enhanced functionality and compatibility with the DALI D4i lighting and sensor control standard.
The NEMA ANSI C137.41 standard specifies covers roadway and area lighting equipment connection interoperability. The 7-pin receptacle provides for dimming control and sensor communications.
The NEMA ANSI C137.41 5-pin connector variant adds support for dimming control, but does not include sensor communications support which is supported by the 7-pin connector.
DALI, or Digital Addressable Lighting Interface, is a dedicated protocol for digital lighting control that enables the easy installation of robust, scalable and flexible lighting networks.
Wiring is relatively simple; DALI power and data is carried by the same pair of wires, without the need for a separate bus cable.
The TALQ Consortium has established a globally accepted standard for management software interfaces to configure, command, control and monitor heterogeneous outdoor device networks (ODN) including smart street lighting.
This way interoperability between Central Management Software (CMS) and Outdoor Device Networks (ODN, so called ‘gateways’) for smart city applications from different vendors is enabled, such that a single CMS can control different ODNs in different parts of a city or region.
D4i is the DALI standard for intelligent, IoT-ready luminaires.
By taking care of control and power requirements, D4i makes it much easier to mount sensors and communication devices on luminaires. In addition, intelligent D4i LED drivers inside the luminaire have the capability to store and report a wide range of luminaire, energy and diagnostics data in a standardized format.

The world would collectively achieve 10,546 TWh of energy savings by 2030 [with energy efficient lighting], a sum comparable to over 40% of the world electricity generation in 2011. Saving this amount of energy would prevent the emissions of 5,400 Mt CO2, a figure equivalent to over 15% of the global emissions in 2011.
Municipalities and utilities across the United States are increasingly confronted with the expensive and disruptive problem of copper wire theft from streetlighting and public infrastructure. Wire theft isn’t merely an economic issue—it undermines public safety, community confidence, and operational reliability. Streetlights left disabled due to wire theft pose safety risks and negatively affect the quality of life in affected communities.

The Persistent Problem of Wire Theft
Driven by high scrap metal prices and relatively low risks of apprehension, wire theft incidents continue to rise, placing significant operational and financial burdens on public works and utility departments. Each incident typically incurs costs for repairs, traffic control, emergency response, and associated liabilities. Typical repair costs range from $2,000 to nearly $5,000 per incident, not including indirect public-safety and service-interruption impacts (Miami-Dade Office of Inspector General, 2013; Inside Lighting, 2024).
Passive Solutions and Their Limitations
Municipalities traditionally rely on several methods to curb wire theft:
Physical Security Measures: Locking junction boxes, installing polymer lids, and deploying wire retention clamps. While simple and direct, these methods have proven limited in effectiveness—thieves often bypass physical barriers quickly, creating ongoing maintenance and replacement costs (CALTrans, 2013; Miami-Dade Office of Inspector General, 2013).
Alternative Wiring Materials: Switching to copper-clad aluminum or steel wiring reduces theft attractiveness, but these retrofits can be prohibitively expensive and disruptive in existing infrastructure scenarios (CBC, 2014).
Marking Technologies: Marking copper wiring with microdots or identifiable chemical signatures can aid in prosecution, but they rarely deter theft outright due to low immediate risk for the thieves (Bureau of Transportation Statistics, 2009).
Legislative and Regulatory Solutions: Stricter laws around scrap metal sales and increased penalties for theft provide long-term support but lack the immediate deterrent effect necessary for stopping opportunistic theft (TET Coalition, 2024).
Solar Retrofits: Converting to solar fixtures removes the copper theft issue entirely, but at a very high capital cost and ongoing battery maintenance and lifecycle limitations
Research and real-world outcomes indicate that while these solutions can offer partial deterrence, they rarely provide comprehensive or sustainable protection, especially in areas experiencing frequent theft (Miami-Dade Office of Inspector General, 2013; TET Coalition, 2024).
Key Gaps in Passive Protection
Passive protection methods predominantly suffer from two primary weaknesses:
Reactive rather than proactive detection: Most municipalities detect wire theft only after the lights fail, giving thieves ample time to remove wires and leave the scene undetected
Limited real-time enforcement and deterrent capability: Without immediate detection and law enforcement notification, thieves perceive low risk, limiting the deterrent effect
Effective theft deterrence, as underscored by criminology research, depends far more on the certainty of apprehension than on severity of punishment (Nagin, 2013). A 2021 study of the Dallas police departmentshowed that a 10% change in police presence has a 3% effect on deterrence.
Passive measures try to make theft harder. Wire Theft IQ makes theft riskier — by ensuring every theft attempt is detected, logged, and responded to in real time. That difference is what shifts theft from a profitable crime of opportunity into a deterrent, unprofitable, high-risk gamble.
How Tondo Addresses Critical Gaps in Passive Protection
Recognizing these critical shortcomings, Tondo is in the testing phase with Wire Theft IQ: a new, 100% accurate theft-detection solution specifically designed to deliver robust, immediate detection and significantly enhanced deterrent capabilities. These innovative solutions are scheduled for market release in Fall 2025:
Physics-Based Proof – Not Guesswork
Detects theft using PLC continuity checks between cabinet and end-of-circuit devices
Provides real-time alerts and logging of evidence that copper has been cut, not just power lost
Battery-Backed Monitoring
Operates even when circuits are de-energized (breaker flipped, utility outage, or storm)
Continues monitoring until copper theft is detected or power is restored
AI Analytics
Cloud IQ distinguishes Outage vs. Theft by analyzing timing:
Power lost but circuit intact = outage
Power lost then continuity broken = theft
Tamper Detection
Supports cabinet and pull-box door/cover sensors
Correlates physical access events with electrical continuity breaks for higher-confidence alerts
False Positive Elimination
Prevents nuisance alarms during outages or maintenance
Ensures law enforcement receives only validated theft alerts, preserving police trust
Event Forensics & Evidence
Incident logs provide time, date, and theft confirmation
Enables police follow-up and prosecution
Cut Location
PLC impedance analysis and topology data help narrow down the likely cut zone
Reduces field crew search time and restoration costs
Proven ROI
Preventing a single full-line feeder theft ($20k–$50k) covers deployment cost
Ongoing savings from avoided copper loss, reduced downtime, and faster response
Tondo’s Wire Theft IQ provides rapid, pinpoint-accurate real-time alerts, enabling rapid law enforcement response times. With the addition of on-pole labeling alerting potential thieves to the presence of Tondo’s anti-theft protection, municipalities can substantially amplify the deterrent effect, aligning with proven deterrence strategies.
Tondo’s PLC and AI-powered solutions provide high-sensitivity holistic monitoring for energized or de-energized circuits to avoid false positives.
Fixture-Based Detection vs. Tondo’s Circuit-Based Proof
Many cities already deploy fixture-mounted lighting controllers similar to those of Tondo’s Edge IQ controllers, that send a one-time “last gasp” signal when power is lost. Some vendors have marketed these devices as a potential solution for wire theft detection. While they can provide partial visibility, this approach has fundamental limitations:
Only detects power loss, not theft: Fixture controllers cannot distinguish whether the cause was copper theft, a utility outage, maintenance, or a breaker trip. All look identical in their central management systems.
Blind once power is off: After the last-gasp message, the device is dead until power is restored. If thieves flip the breaker first or exploit a storm outage, the controllers cannot report theft at all.
High false positive rate: Storms, grid failures, and routine maintenance often generate the same alerts as theft, overwhelming operators and eroding police trust.
Limited location accuracy: Controllers can sometimes infer a rough location if the cut happens while energized, but once de-energized, no location information is available.
Tondo’s Wire Theft IQ addresses these limitations:
Physics-based continuity proof: Instead of inferring theft from power loss, Wire Theft IQ directly monitors whether the copper conductors are intact.
Battery-backed detection: Wire Theft IQ continues to operate and communicate even during outages, storms, or breaker flips — the very conditions when most thefts occur.
Time-based event intelligence: Tondo’s AI and Cloud IQ can distinguish outages from theft by analyzing event timing, ensuring accurate classification.
Reduced false positives: Because the system proves continuity rather than guessing, it avoids nuisance alarms and preserves law enforcement trust.
Operational efficiency: Wire Theft IQ provides clear theft events rather than floods of ambiguous alerts, allowing field crews and police to act quickly and decisively.
fixture-based solutions cannot provide the accuracy and trust that Wire Theft IQ offers. For municipalities facing escalating copper theft, the difference between inference and certainty determines whether incidents are prevented — or repeat again and again.
Conclusion: Integrated Solutions for Long-Term Success
Tondo’s goal is to make successful wire theft unprofitable, and to effectively protect public assets from wire theft, municipal and utility leaders can adopt a layered solution that proactively detects, deters, and enables immediate response to theft-in-progress.
When part of a comprehensive, layered approach integrating proactive technology, real-time alerts, targeted physical measures, changes to metals recycling requiring sellers’ identification and record-keeping by recyclers, and coordinated law enforcement responses represents a layered best practice for wire theft.
