Amping up your home security on a budget in time for winter? This is the device you need: a genius smart entry sensor that sends you messages when doors or windows are opened. 

The best part? These devices are a fraction of the price you'd pay for an alarm system.

Here's how they work: you download the app, then peel and stick the devices on vulnerable doors and windows; you'll receive instant notifications if the doors or windows are opened via the app (or via Alexa if you're hooked up), no matter where you are in the world. 

You can, of course, arm and disarm the devices from your phone to, so that you don't get alerts when you or other family members are home.

We think it's an affordable way to monitor your home – perfect for anyone on a budget or if you're renting and your landlord won't pay for an alarm system. Pair it with a video doorbell or wireless security camera like the lightbulb spy cam we found yesterday and your home security is sorted – at a smart price.

Want to know about the US version of this particular device? If you're a pet owner, you don't need to worry about your energetic cat triggering your sensor – the Kangaroo has built-in Pet Rejection Technology that is smart enough to disregard them so not to worry you without need.

And both devices – UK and US – have long battery life so you won't have to worry about changing them in the near future.
