A burglar takes an average of less than 30 seconds to break into a house or apartment. According to the nationwide police crime statistics, the perpetrators in most cases enter through easily accessible windows and apartment or balcony doors. Modern security measures like the following five window sensors can help to protect your home.

The smart solution: 3-pack door and window sensors from Netatmo

The waterproof sensors from Netatmo are not only used for burglar protection on windows, they are also ideal for everyone who asks themselves every day: "Did I actually close all windows and the front door?" You can use the smartphone app at any time to check whether the doors and windows in your home are closed. In the event of an attempted break-in, the user is notified immediately: The sensors detect both strong vibrations and the opening of doors and windows. To do this, the smart gadgets, each powered by two AAA batteries, simply have to be glued to the window or door.

Well connected: door and window contact from Bosch Smart Home

First the bad news: Similar to the window sensor from Netatmo, the Bosch window contact only works in conjunction with the Bosch Smart Home Controller. The good news: If you own several networked Bosch Smart Home devices, you benefit from a sophisticated alarm system.

The sensor detects open doors and windows and reports them to the smart home system. If you attempt to tamper with the windows, he can also trigger the siren of the smoke alarm or automatically flash the integrated Philips Hue lights so that as much attention as possible is drawn to your home.

The Bosch sensors are not only used for burglary protection. They also send a signal to the Bosch thermostat as soon as a window is opened for ventilation. The smart thermostat then automatically regulates the temperature to save heating costs.
