OSI Wifi Alarm System

Protection for break-ins & Emergencies

Be the first to know when doors and windows open. Once an intrudor enters your property and triggers either your door/window sensor or PIR Motion sensor, the OSI Mini Alarm Hub will immediately send a notification to your smartphone or tablet, letting you know which sensor has been triggered! At this point of time, you can choose to call emergency. Also, if you are in the home and feel you are in a possible dangerous situation, you can press the panic button (SOS) on the Smart Life app to quickly sound the siren.

OSI Wifi Alarm System

Complete control from Smart Life App

There is no need to press any alarm codes when entering your property! Arm, disarm, make setting changes, receive notifications and monitor your system from wherever you are using the Smart Life app. You can even connect the OSI Wifi Mini Alarm System to Alexa or Google Home through the Smart Life app so you can arm and disarm with voice control or add it to your Routines! The system also includes 2 remotes which you can attach to your key chains giving you more ways to conveniently arm and disarm the system.

OSI Wifi Alarm System

Works great with the OSI Wifi Mini Camera!

Place a few of these little 3.5" tall OSI Wifi Mini Cameras near your propery entryway to get instant confirmation as to who or what caused the alarm sensor to trigger when you recieved the alarm notification to your smartphone/tablet. This wifi camera conveniently uses the same app used for the OSI Wifi Mini Alarm System, so as soon as you get a notification you can open the smartlife app on your phone and check the live camera feed to see what is going on in your property. This enables you to make a sound decision as to whether or not you should call emergency immediately!


Also, because the camera features motion detection, if there was in fact an intruder in your home you would also have recieved a second a motion detection notification from the OSI Wifi Mini Camera which means it also would have recorded the person entering your property. So, all you have to do is open the Smart Life app and check out the recorded event! Watch this Video to learn more!

#1 Choice Wifi Alarm System

#1 Choice for Apartments and Frequent Movers.

Whether you live in a studio apartment or a six-bedroom house, security systems help protect your property from intruders, package thieves, and your neighbor’s 9-year-old kid who keeps ding-dong ditching your door. But if you live in an apartment, security systems can be tricky. Yeah, you want to arm your entryway, but most landlords would rather their tenants didn’t drill holes in the wall or install complex security systems you have to take down later. Especially if you tend to move from one place to another fairly frequently (say, every two years or so).

That's why the OSI Wifi Mini Alarm System is best overall for renters precisely because, it's simple, super affordable, it’s easy to install, and it does its job. Take down and set up your system in less than 10 minutes. Spend less time dealing with unsightly wiring and more time actually getting work done!

    Quality product and easy to install

    Posted by Jeff c. on 2022 Aug 22nd

    I needed a security system for our cottage and thought I would give this OSI mini alarm system a try. I have purchased products from OSI before and was pleased with the quality, service and support. This system is exactly what we needed. The setup was extremely simple, and easy to operate through the Smart Life App. You can share the device with other users which is great for our family cottage and the multiple people that make use of it. I just need to order a few more door sensors and I'll be good to go. Thanks OSI!!!
