IoT, Technology

安価ホームIoTの時代がやってきた / Here comes cheap home IoT!

Xfinity Home, Nestなどがアメリカで導入されて久しく、それぞれ結構高いながらもそこそこの成功を収めています。産業IoT以外のConsumer IoTでは、Home IoTが本命、その中の大本命がボイスコントロールだとすると、その次はやはりHome Security/Controlということになるでしょう。

Xfinity Home, Nest and others has prevailed for a while even though their service and/or devices are a bit pricy.  Except for industrial IoT such as factory IoT, among consumer IoT, “home IoT” is the heart of IoT.  Provided that most used one of them is voice control such as Amazon Alexa, next  to it should be home security and control.



In Japan, home IoT doesn’t seem to be hot now.  One possible reason would be cost and phycological and technological hurdle to adopt it.


そんな中、アメリカで格段に安く、導入が簡単なホームセキュリティデバイス・ツールである Motion Sensor – Kangaroo なるものを購入して試してみましたので、体験レポートを下記します。

In the States, there is “Motion sensor – Kangaroo” which is very reasonable and easy to adopt.  Once I saw it in internet banner, bought it and installed it in my house.  Here is the report.



As a result, although telco and cable operators would think they want to monetize home IoT now, with this cheap and easy-to-install home security IoT which serves users well enough, I thought they had to reconsider their strategy and positioning for home IoT.


Kangaroo Home Security $30 (incl. shipment and app)(約¥3,300 – 送料込み、アプリ込み)

Security for all.
Our Motion Sensors are batteries-included,
peel-and-stick, app-controlled easy.


Shipped in a neat box.


Behind the box, value propositions are described briefly.


A user manual is included in the box.  Recently inclusion of detailed manual is rare to see.


Although the detail how-to-use app is not written, some of key instructions are explained in the manual.


On top of it, there is a sticker to notify buglers that this house is protected by device, which is nice to have.


The appearance of the device.


Before you peel the seal, we are supposed to install the app.  (Because the position to put this device is important for an user and the company.  Detail will be explained later)


When you pull of the insullation tab, the light flashes on.
(To save battery consumption, this light doesn’t get turned on after the setup)


Download of the app.


Here you’ve got to input your phone number.  For premium version, since you can get SMS and voice call notification you need the number, however for the freemium version you don’t need the number.  They are unnecessarily collecting personal information.


Naming your device.


Pull the insulation tab.

Finding the device with bluetooth between smartphone app and the device.


Found it!


その後に、通常このセンサーが使う(Wi-Fi APからの)Wi-Fiを選択します。
Bluetooth とWi-Fi の切り替えなどここらへんから原理的には少しむつかしくなります。
Next, select the Wi-Fi (from Wi-Fi AP) this sensor uses.  This is a little bit technically tricky to understand.  However they kept UI simple.


Once connected to Wi-Fi, the sensor can connect to internet.

This “How This Works” part is important in our real life usage.  The sensor can reach 15 feet, approximately 5 meters and look straight ahead and 60° to the left and right, in total 120°.
You can hardly go back to UI and it is not good for users in terms of UX.


This is how to avoid false alerms.  If you get too much of them, you come to think why you bought this gaget.  Thus the manufacturer is paying a lot of attention to avoid it.


Pets can be a cause of false alarms.  Again, if users think this IoT device is useless because of false alerts because Kangaroo is selling this device through Amazon etc., it would be a big problem for them since user review is critical in those EC sites.


Those settings are for having multiple sensors.  I just thinks “why bother to configure this for first device?” but in software perspective this is something you can’t do with.



I installed the sensor device so that I can catch someone intruding my food warehouse.


I could fit it to the side of bed nicely.  Because it is adhesive tape based, super easy to attach.  And since the device is so light, it won’t be fallen off for a long time.


I turned on the sensor and armed my food.  And when a person cross the area,


ただし、通知を見て「こりゃまずい!」と思ったら画面右上のCall 911(日本の110番)で警察への緊急通話が出来る。(なかなか微妙なところではありますが)
The app detects the movement and intrusion, notify the user within the app and smartphone notification function.  Although this sensor doesn’t have video recording functionality, if you think “OMG, here comes a robbery!”, you can call 911 for the emergency call.  (This probably won’t be allowed in Japan though)

After you tap “Call 911” button, you see the popup before you make a call.


You can register Kangaroo’s inquiry phone numbers in your contact list with just a simple action.


Then, how they can monetize from this business except for $30 device including shipment?   They have $5/mo. “Complete Plan” and with it you can have service shown above.

  • テキスト+ボイスコール通知
  • 24時間365日 センター監視
  • Alexaインターフェースの提供

24時間365日 センター監視というのは心強いですが、カメラが無い中、どうやって誤検知かどうか判断するのでしょうか? 今後デバイスは追加される予定らしいので、要注目です。
24/7 pro-monitoring sounds assuring, but without camera device, how can you confirm the alart is false or not?  They says they will release new devices soon, we have to watch them out.


And with the Complete Plan, they would contact authorities when they detect intrusion.  This is almost impossible in Japan lol


ボイスコントロールデバイスとのインテグレーションも有料。いくつかはcoming soonとなっています。
Integration with Amazon Alexa and other voice controll device and IFTTT are in the Complete Plan and some of them are “Coming soon”.


Finally, you can switch on/off the monitoring from the app very easily.



Security is very hard to define, especially how far we need to fave.  But having easy/cheap one as an option is always good thing.  With $30, this device/app is worth while trying.
