OSI Alarm System Gen 2 (4G), 11pc, DIY, Motion & Entry Sensors, Wireless Siren, Remotes, App & Alexa Compatible Self Monitor(No Monthly Fees) or 24/7 Alarm Monitoring (as Low as $15/mo)

I don't usually write a review but I felt I had to due to the fact that for several months I was looking to replace my Swann Security System and came across your product. After doing some research regarding this security system I am very impressed with the functionality as well as the ease of use which is really top notch and for the price you can't go wrong. I really like that I can take it off my network and the power can go down and it is still working. I want to personally thank the team at OSI for creating such a great product. I can wait for what the software updates have instored. Another happy customer. Thanks Eddie

It Activates from Panel, Cel App, Remote control and Can Configure easily to sends Alerts via CelApp, SMS and Phone Call using a prepaid local area Cel Chip. You can configure every sensor with a name, so you know what door is open, no issues with sensor distance between 3 floor story. Can configure if you want alerts ehen door opens or not, Working perfect in Mexico

I bought this system for an elderly parent who was wondering. It is a great syatem for that and more. Setting up the system is easy and quick. After you plugin the unit, it will walk you through the setup and it's intuitive and easy to follow. The hardest part (for me) was taking the tiny stickers off of the back fo the door units and figuring out where top place the motion units. One of my motion units is not currently functioning, but the other does a fair - if not top notch - job of detecting motion. Angles are fairly limited on the vertical, and the horizonal seems to be a bit more limited than listed. However, they still catch a hallway (I was just able to get a little closer than I would like, and 'sneaking' along the side had a limited success. Door alarms don't need to be perfect, they work just find sitting on trim and still engage the magnetic lock. The alarm is loud, and the light is bright. Except the one motion, which i suspect is batteries or some such, all pieces connected quickly and were easily editable on the app. On Portability This is such a simple, easy to seutp system you could easily use this as a portable system utilizing screws, zip ties and command strips. It's small, light and only needs to have a plugin for it to work. Overall, this system holds good value. Battery life will hopefully hold out but I will report if not. The control panel is easy to use and modules are easy to setup.

Easy to install and works great! I now have motion sensors on entry, doors and windows. You can set the timer on delays before alarm goes off upon leaving or entrance. If you're like me and don't want any wires showing you'll need a 12V DC transformer. Very satisfied with this purchase and ease of use.

No monthly monitoring fee and it reminds me of a Vivint system. Two grips, the door and window contacts if that is self stick tape it's the worse I've ever seen, but nothing a $5 roll of foam double stick tape can't fix. Other is the alarm panel is VERY sensitive to movement and will go off if it thinks it's tampered with. Put it on a wall that is solid and not subject to doors slamming and such. But this is a fantastic alarm system easy once you don't overthink it to install and I added camera outside and in that are great additions for our vacation house. It notifies you by text anytime something happens, I think is great and not paying monitor fees!

It was very easy to install. I love it. What’s really neat is you can come home and know that nobody’s been in your home and if there was, they would probably leave very quickly.

My biggest challenge was getting it connected to the Smart Life app; I narrowed it down to the 5Ghz band which my phone was connected to (could not force it to 2.4Ghz), so I just kept trying until it got added. Setting up is a breeze from there on out. I do wish that the buttons on the remote controller had a bit of a recess - I find myself inadvertently arming the thing simply because my palm held on the controller a bit too tightly, every now and then. Besides that gripe, I only have good things to say about this system. Works well with my Google smart home, and I find that the balance between cost and reliabiliy has been struck here.

5 months in and we loved this DYI alarm at first but not so much anymore! The doors used to beep when you open a door or window but now it has stopped. The batteries in the door and window sensors need to be changed often. The speaker on the touch screen is so distorted it sounds like it is blown. Customer service is non existent as it’s online and it just takes you through common problems. They do software updates but the latest update didn’t fix our problems. This is worthless to us at this point. I guess we just need to buy a different brand. Update on 12/01/25, One month after our not so good review I figured they may reach out to help correct these issues but still no customer service. As stated in original review stay away from this one!
