Korner is home security anyone can use and everyone can afford. Existing solutions are expensive and complex to install and use. Through innovation with sensor technology, Korner has refined the notion of home security to its simplest form, creating a solution that is inexpensive and extremely easy to install, thus providing home security to everyone, not just affluent homeowners. Our offering is comprised of a Stick that plugs into a user’s router and communicates wirelessly with Tags (with a reusable adhesive) that are applied to doors and windows. Our Tags are patent-pending one-piece sensors that fit snugly into the corner of a door or window and contour gently with the adjacent frames. In addition, we allow users to pre-populate their App with contacts for friends, family, and neighbors such that any alerts can be instantly forwarded to their personal networks with the press of a button. This supports an inherently social form of Neighborhood Watch, and provides a basic platform for communities to interact.

Latest update crashing system

I was a kickstarter backer and have loved the Korner system. Really appreciate you updating the app to work again but now my system just hangs in “Disarming” so I can no longer use it (even restarting/ after disconnecting and reconnecting the stick) . Any advice or possibility for an update? Thanks!

Serious problems

The system keeps disconnecting (almost every day now), and doesn't reconnect by itself. I get a notification that the "stick is missing", and there's really nothing I can do to fix it (disarm the system, disable the siren, silence the alarm, change settings, etc) while the system is disconnected, so every time I get into my home the alarm goes off and I have to physically disconnect the stick from the router to stop the noise, and then reconnect the whole system. There is absolutely nothing wrong with my internet, so this is 100% a Korner's problem.
And if this wasn't bad enough, I find outrageous that THERE IS NO KORNER CUSTOMER SERVICE!!! All one has access to is a list of FAQs, -half of which are useless-, but there's no way to contact them; and on top of everything, they have the impudence to charge a yearly fee to keep the system active.
Korner seriously needs to fix this issue. This is not a problem that only affects me; but also affects the people around me. My neighbors have already come to my place to complain because the alarm wakes their kids up when it goes off late at night (sometimes after midnight).
I am very dissatisfied with this product and this company.

Opening the Door Slowly Deactivates Security

Not only has this not been updated for over two years, the company hasn’t bothered to fix a known security danger. If an intruder known to you who knows your “security” system is Korner very slowly opens your door or window, though alarm doesn’t go off. I was wondering how my ex or my landlords were circumventing my alarm and getting into my old residence. It was only when I got the sense I should research before activating it here that I learned it was only a useful deterrent if someone doesn’t know you have it. Otherwise, it’s totally useless.
