Client - Zentra

Product: Shield +

Zentra_home screen - without alert.png

A Sensor-Based Predictive Maintenance System for multi-family apartments.

Zentra is a seamless security solution designed to solve the everyday problems of shared property access. It is the convergence of exceptional security and convenience.

The exponential growth of multi-family properties in the US comes with its challenges. While it may not be possible to address all these challenges at once, we can focus on trying to solve a part of it. Maintaining large properties entails significant costs, but leveraging modern technologies can substantially reduce the thousands of dollars spent on maintenance.

THE PROBLEM: Increase in maintenance costs in multi-family apartments and delayed repairs

THE SOLUTION: A pre detecting device that keeps track of all major machines and detects any issues beforehand

IMPACT:  Lowered costs and profits for owners

Properties spend thousands of dollars each year to repair machines and other property damages. While it can completely not be prevented, there is a chance of reducing costs by using preventive methods. 

efore examining our competitors, we wanted to closely analyze the market we're operating in. This involves understanding the market's composition, projecting its future scope, and providing some supporting statistics. In 2018, there were 56.15 million multifamily homes in the United States, with this number projected to reach 155.25 million by 2023 [Reference]. Typically, operating expenses consume 35% to 50% of the gross operating income from rent in multifamily properties[Reference]. 

The Smart Home Security Market is expected to reach $112.6 billion by 2032, growing at a 16.2% CAGR, according to Allied Market Research. As the modern security industry becomes increasingly essential with the industry's growing population, our goal is to brainstorm ways to contribute to this business and further expand the market.

For our competitive Analysis, we completed a detailed analysis of the companies Securitas, Dormakaba, Kisi, HID Corporation Assa Abloy, and sister companies owned by these companies. Considering online learning is a huge market, a lot of companies provide similar services. We looked into various such companies but picked four companies that came close to our clients as competitors.

Maintenance of any property primarily impacts three groups: the residents, the owners, and the maintenance staff. Each group experiences different effects. The common core problem, identified through understanding the pain points of all three parties, is: "If only they knew the problem earlier." 

We spoke to 10+ residents and 3 property owners resulting in some similar issues from each Interviewee. 

What our Residents said...

“ It took 3 days for my Fridge to get fixed, we just had to move things from the vent!! 

“I don’t know what exactly is happening after I have reported a maintenance request, is it even received?”

“ My water pipe broke like 3 times last winter because I forgot to turn on the faucets!“

What our owners said...

“ we receive like 3-4 requests a day and 120-200 a MONTH, few of them are really silly (P.S -I Know I’m not supposed to say that)”

“We receive work orders in units, but issues outdoors go unnoticed for days! ”

“Most of the requests we get can be solved within a minute or two and some can be avoided if the residents are a bit more careful”

Subsequently, we analyzed the data by employing Affinity Mapping and Empathy Mapping techniques, structuring our findings accordingly. We then created personas for each stakeholder to understand their individual needs and goals. 

Research Analysis


After reading several articles and conversing with a few individuals, we have gathered crucial insights to establish a strong foundation for our project.

Design Solution


After thorough consideration, brainstorming sessions, and receiving feedback from experts, we opted for our MVP solution, a pre-detecting maintenance software that keeps a check on all systems and detects issues in its initial stages that can be rectified before it gets worse. 


Running behind schedule, you find no water in the bathroom. The property manager explains a burst pipe will leave you without water for at least 4 hours. With only 20 minutes to spare, you must quickly handle cooking, showering, and head to the office.

With Shield+, we detect potential pipe freezes early and automatically activate valves to supply hot water, ensuring a seamless morning routine. Residents and property managers are satisfied with the hassle-free experience.

How does the Solution work? - Technical term version

We aim to leverage cutting-edge sensor technology embedded in AI platforms such as Alexa, Siri, and others. Our goal is to create a predictive maintenance solution that utilizes machine learning to identify and address potential issues before they lead to equipment failure or service disruptions.

Let's look at the IOT Ecosystem Analysis to understand the process better.

Business Model


Our solution will act as an additional revenue model for the company. A few possible revenue models are subscriptions, software licensing fee, and maintenance and Service.

Screenshot 2024-01-04 at 6.58.28 PM.png

Multiple plans that suit the property manager - UPremium, Premium, Standard. Based on a number of sensors, maintenance, updates, and coverage of property.

We provide an all-in-one application with software and hardware integration!
Aid in extended life of assets, reduced maintenance cost.

How can we add Value?

  1. Partnerships with companies like MRI Software and sensors manufacturers.

  2. Provide software updates and service for hardware.

  3. Research and Development of smart systems.


In summary, it reduces the time dedicated to resolving minor issues and cuts down on property managers' expenses related to equipment downtimes through preventive maintenance. The US holds the majority share in the predictive maintenance market, constituting 35% globally.* Creating an accessible solution positions us as an early market leader, capturing a substantial market share.



We tested our product with 2 Property Managers and 5 Residents. 


  • The property managers loved the instant update feature of the sensors. 

  • Solving issues before they worsen saves a lot of money for the Property managers.

  • They were concerned about the "Check Camera" feature in the product. 

  • The property managers were concerned about the "self-diagnosis" feature in the hands of the residents. Wanted a more clear function and user flow for this feature. 


  • Residents found the self-repair and self-diagnosis feature the most helpful. Their concerns about how fast the issue will be resolved will be answered here. 

  • Residents were also concerned about the "check camera" feature in the product. 

  • Residents suggested d that they also wanted a live progress update of their maintenance reports. 

In conclusion, commencing with the refinement of the prototype in response to the feedback garnered during the evaluation phase, our iterative process involves continuous testing and evaluation with a broader user and expert base. Concurrently, we initiate the development of a framework for the subscription model, laying the foundation for the upcoming phases of our project.



The highlight of the project was our intensive 1-2 weeks of brainstorming, culminating in a final 5-hour group call. This phase was incredibly educational for me, as I gained insights into different perspectives, meticulously examined each part of the solution, experienced a "eureka" moment, and more. Despite the intensity of the discussions, this remains the most memorable part of the project. Without that rigorous session, we wouldn't have achieved the solution we did. It was worth it. 

who made this project a success.
