Stretch Goals

 

Meet Sentri

Sentri is a smart home device that evolves the traditional security system to give you a 360-degree view of your home, guarding everything from your home’s security to tracking its physical state. Sentri comes preloaded with a HD video camera and motion detector that you’ll find in typical security systems, in addition to a set of sensors that measure and display your home’s temperature, humidity levels, and air quality, making it the smartest security system on the market.

In addition to a sleek screen and user interface designed to fit elegantly anywhere in your home, take the intelligence and peace of mind Sentri delivers no matter where you go with its free accompanying mobile app. Its real-time alert system, designed to learn from and adapt to your personal preferences, alerting you of irregularities that matter to you and your home, whether it’s triggered by unexpected motion that could signal an intrusion or a sudden fluctuation in temperature, that could mean the start of a fire.

And unlike traditional security systems, which can take hours to set up and cost upwards of $1,000 a system to install in addition to monthly service fees, Sentri is ready to use out of the box with no professional installation service required. Simply plug in, power on, and connect to your home’s WiFi network.

With Sentri, we imagined – and built – a home that is as intelligent as you are, one that not only provides you with a smarter view of your home, but also empowers smarter decisions that result in safer homes.

How Does Sentri Work?

We designed Sentri to fit into your home not as another tech gadget, but as an intelligent and constantly learning monitor that can be customized to respond to your unique needs to create a safer home. Use Sentri to:

Being away doesn’t mean you shouldn’t know what’s happening.  Sentri’s built-in notification system alerts you of any irregularities – whether it’s triggered by unexpected motion that may signal an unwelcome visitor or a sudden increase in temperature that may indicate the beginnings of a fire – so you’ll always stay informed.  

Its built-in learning algorithm is designed to learn your personal habits and preferences to alert you of the events that matter most to you, and minimize the challenges of false alarms that exist in traditional security systems.   And of course, you’ll always have the choice to customize Sentri’s settings to teach it to inform you of the changes you care about most in keeping your home safe.

Once you receive an alert from Sentri’s intelligent response system, check in on your home using Sentri's built-in HD camera and mobile app at any time, anywhere (or simply check in to say hi to your household puppy!).  

Sentri is more than a home monitoring device – it’s designed to be an entire response system that connects and controls all your smart devices, all from one single destination.

Received an alert that your front door has been unlocked for more than 10 minutes? Use Sentri’s mobile app to remotely lock your door.  Check in on the status of all your smart devices directly on the Sentri screen or through the mobile app, and integrate views of all your smart devices’ activities and trends in one view.

Always know the state of your home using Sentri’s sensors and intelligent response system.  Tap into the vital stats and trends of your home – humidity, temperature, air quality, motion and sound – at any time either on the Sentri display or with our free companion smartphone app.  

Have a Sentri in your nursery? Monitor temperature, humidity, and air quality to make sure everything is just right for your newborn. Curious to see how your average home temperature correlates with your energy bills and the weather? Use Sentri's trending views to show your home's temperature and map them against fluctuations in weather.

Customize your views on both the Sentri display and your mobile device with the information you care about most to best secure your home.

Sentri isn’t designed to be your run of the mill security system -- it’s meant to be personal in every way. And just as Sentri gives you the ability to define what security means to you, it also gives you the ability to define how Sentri looks in your home. 

Customize your Sentri using our pre-loaded set of designer themes to display the information you care about most in a way that’s uniquely your own. Unlike traditional security systems, which can often be bulky and conspicuous, Sentri is designed to fit into your home, based on your individual style. Choose your own background, clock style, and dashboard layout depending on your preferences. 

However you define security and the design of your home, Sentri empowers you to make it your own.

Why Sentri

We firmly believe in designing for ‘humans first’ and developed Sentri to deliver actionable, adaptive information to keep your home secure using the following guiding principles:
  • Simple elegance: The best technologies are the easiest to use. Sentri is ready to use right out of the box – simply plug it in, power on, and download the Sentri smartphone app. No assembly or installation required. Hang up your Sentri on the wall, or set it right on your shelf and let Sentri take care of the rest.
  • Intelligence within reach: Minimize the rate of false alerts and create a security system adapted specifically to you with Sentri’s built-in notification system that not only keeps you in the know, but also learns -- and acts on -- the alerts that matter most to you. 

    One of the biggest challenges traditional home security systems face is that most alerts delivered are false alarms, leading to many households opting out of security systems, or simply not turning their systems on.  With Sentri, maximize your home’s security with timely and accurate alerts.
  • Empowering you: While safety at home is essential for everyone, we know that your home and what security means is as unique as you are. Take control of how your Sentri looks, feels, and behaves by customizing when and where you want to see certain information and alerts. From choosing the background for your Sentri to showing which sensors are displayed and which smart devices are connected, always stay in control of your home.  

Product Specs

In the past 13 months, we’ve worked tirelessly to refine Sentri’s design and functions, and when you receive your Sentri, this is what you can expect to find inside:

Hardware

Software

Backed by bank-level security

Security is paramount to Sentri. Just as Sentri guards your home, all sensor data and video transmission is secure with Sentri.  Sentri protects your home information uses state of the art “2048 bit RSA encryption,” the standard protocol for most bank-level data transmission so that your data will be safely guarded.

The Technology Behind Sentri

Knowledge is power and Sentri can help deliver that knowledge for your home when and where you need it.  Using its built-in sensors, Sentri collects stats and alerts you when necessary.  If you think a notification is irrelevant, simply respond “No action needed,” and Sentri will learn your response to make it even smarter and tailored towards your personal needs. And the more you use Sentri, the more relevant it will become for your home and life.

Sentri also uses state of the art geofencing features to learn whether or not you’re home.  When at home, your smartphone will automatically connect to the local WiFi network, alerting Sentri that you’re back.

Open API

We believe that we can create a smarter future together.  Our platform and API is open to developers around the world; if you’re a developer, check out our reward designed just for you.

Using Sentri as a hub, developers can imagine and create any number of connections to our platform.  Use Sentri’s intelligent response system and sensors to get coffee started in the mornings based on your actual waking patterns.  Or have Sentri remind you of the groceries missing from your refrigerator as you go into a grocery store.

Together, let’s build smarter and safer homes.

Development stage

We currently have a working prototype and we are now focused on
  • Finalizing the electronic schematics for the final product
  • Improving the user experience and UI design
  • Fine-tuning the user experience of the app
We will soon begin the process of:
  • Pilot production
  • Product certifications
  • Production tooling
  • Packaging design

 3D-model of Sentri

In the past year, we’ve completed multiple working prototypes. Now we are finalizing the electronic design and getting ready for mass production. In the beginning, we built a proof-of-concept prototype and examined all the sensors with Arduino UNO board to identify reliable components which fit our needs. At this stage, we designed the verification process to make sure every sensor works properly and responsively.


After all components were identified, the second prototype used an Android device to connect to the selected components. Its powerful ARM processor allows us to do more complex computing to verify our software and algorithm. We also defined the communication protocol between the smartphone app and the prototype. The results show that our connection and response times are more efficient than similar devices on the market.


Right now all we are on the EVT (engineering verification test) stage. We have designed our electrical schematic to squeeze all the components onto one PCB board. We are fine-tuning the schematic design in order to minimize signal interference. Sentri uses an ARM Cortex-A7 level CPU and a powerful GPU to deliver the ability of showing animations on the display. 

We chose an Linux-based operating system and framework that maximized flexibility for software development and allowed our users to ultimately customize Sentri to their own unique needs. At the same time, we are working on the cloud infrastructure and fine-tuning the app  to deliver the most intuitive and simple user experience to you.

While the engineers worked on the electronic and software aspects of Sentri, our industrial designer built out Sentri's mechanics. We used a CNC machine to create the casing mock-up and verified that all the electronics can fit into one device. 

Why we need your support

Your support is critical to our long term success. While we’ve done the heavy-lifting in building out the hardware and software to prove our thinking behind a connected home, we need your help to scale this vision and bring it to market at an accessible price point. Our ultimate goal is to build a community of Sentri-powered homes that lend itself to smarter and safer neighborhoods.

We will be taking the funds from Kickstarter to move directly into tooling and production, and have agreements with OEMs in Taiwan to begin production as soon as funding is secured. We expect Sentri to retail for $349+.

Risks and challenges

While any new endeavor involves risk, we’ve made every effort to mitigate these risks for our backers and fans. We have already completed a working prototype and have secured our supply chain in preparation for mass production. Despite our expertise and careful planning, there are risks to this project. We've identified and outlined the following key risks to our project below:

-Hardware
The more pre-orders we receive, the better our hardware can be. Since the beginning, we've always made it a priority to include only top-of-the-line components in our device. Manufacturing at larger scales because of higher volumes of pre-orders means that we can afford to include even more high-quality components.

FAQ

  • Yes. You can switch between Fahrenheit and Celsius easily by your smartphone APP.

    Last updated:
  • It really depends on the size your home. Here is the basic rule. 1 Sentri for 1-2 bedroom(s) apartment with one main entrance. 2 Sentris for 3-4 bedrooms house with two entrances. 3-4 Sentris for a bigger house. There is really no limit or restriction about how many Sentris you can have in your house. You can put Sentri in every single room and entrance if you want.

    Moreover, Sentri will be the perfect gift for your parents, friends who just moved to a new house, dog/cat lovers, or families who have newborn. =)

  • While Sentri already comes pre-loaded with a range of sensors (motion detector, thermometer, humidity sensor, and air quality sensor), Sentri can also detect the presence of other smart devices via WiFi and Bluetooth networks.

    Today, there is a clear trend towards openness and shared connectivity in the smart devices and Internet of Things (IoT) community. Most home automation devices provide open SDKs to connect with other smart devices. Examples of open platform and frameworks include AllSeen Aliance(http://bit.ly/1jkWlE5) and AllJoyn (https://www.alljoyn.org/).

    As long as these smart devices have APIs/SDKs Sentri can tap into, Sentri will integrate with them. Once connected, simply view and control all your smart devices from Sentri's mobile app. Our dream is making Sentri the perfect hub in your smart home. Current home automation on this list include:
    ● Nest - Smart Thermostat
    ● Wemo - Smart switch and power outlet
    ● Hue - Smart light bulb
    ● Lockitron - Smart wireless lock

    We are always expanding the number of smart devices we support, and are closely watching opportunities for integrations with other products like SmartThings, Snugr Thermostat, and Ninja Sphere.

    Sentri has always been first and foremost about designing for our users, and we deeply value the views of our backers. Feel free to give us suggestions and we will continue to evaluate them as we consider integrating these features.

  • Our first stretch goal will be to include an Ethernet port to Sentri, making it more accessible. If the Internet connection is lost, users will receive an alert on their mobile Sentri app that informs them that their network is currently down. Once Internet connection is restored, Sentri will automatically re-connect with the network and no data will be erased (for example, you can still go back and see historical trends in temperature, humidity, and air quality).

    Last updated:
  • While Sentri does have its own memory storage unit, it’s primarily used for the Sentri operating system. However, Sentri offers media archive features so users can track and record irregular events (e.g., snap a picture when there is unexpected motion). We have also set an SD card slot as one of our stretch goals, which can be used to store video captures from Sentri. On average, a standard 720p video for 90 minutes would take ~12- 13 GB of data.

    Last updated:
  • Whenever Sentri loses Internet connection (which can also be triggered by someone unplugging Sentri), users will receive an alert informing them of this irregular event. Additionally, we’ve added battery support to our stretch goal so even if the power connection is lost, Sentri can still connect and keep you informed of what’s happening at home.

    Last updated:
  • While touchscreen capabilities have always been on our roadmap, we've heard this feature come up time and time again in conversations with our backers. As such, we're extremely excited to add touchscreen as a stretch goal for our campaign now. If we're able to raise $500,000, we'll be able to introduce this feature now, which means more a more direct interface with your Sentri device, allowing you to directly arrange how your Sentri looks from the screen itself. Of course, you'll always still have the ability to control it with the mobile Sentri app.

  • Sentri supports universal power supply. 100-240V.
    And support the plug type in most of the countries on Earth, like US, Europe, TW, AU/NZ and CN.
    We will send out a survey before shipping to ask our backers about the plug type.
