Keep intruders away

Entry Sensor

Imagine always having a frient keeping an eye on doors and windows in your home. Someone who lets you know if you forgot to close a window. A frient who warns you if someone enters your home when you’re away. Someone who wants you to enjoy being away on vacation – and not worry about the safety of your home while you’re gone.

Now that’s a frient!

One step ahead of intruders

Placed on a door or a window, the Entry Sensor tracks when it's opened and closed. You'll have peace of mind, knowing that your home is safe - no matter if you're at home or away.

With this new frient, you'll be alerted immediately if someone is opening a window or door in your home – allowing you to act before the intruder does.
