With Smart Home, most people immediately think of the smart speakers from Amazon, Apple, Google and the others, which conveniently control light, music or air conditioning via voice control. But it can also be a size smaller. Monitoring your own four walls also works via app.
Homeowners have the possibility to check what is going on in the house from on the way. Is a window still open? Is the stove still on? Have you forgotten to turn off the heating during your holidays? What makes mobile phone surveillance so interesting? “Many people do not want to invest in an expensive smart home system for home monitoring, with which the heating can then be switched off directly. It is enough for them to get a short alarm and then quickly turn back and close the window themselves,” reports the expert for mobile home surveillance and Managing Director Manfred Sarrazin of Techno Trade.
Estate agents or property management companies already use such apps in vacancy management, for example. Techno Trade develops various smart sensors and the app to monitor real estate. All data and fault messages from all sensors are recorded here. Various alarms can be set for this purpose. Motion sensors can detect if someone enters the building, heat sensors can control the temperature and detect water sensors if, for example, a pipe is leaking and water is leaking. “Technically, this is possible by attaching small sensors at the respective point, which send signals to the App user via W-LAN via a radio station,” explains Frank Reiser, business IT graduate at Techno Trade. What is useful for professionals can also help owners to always and easily maintain their property.
Manfred Sarrazin describes the situation of Techno Trade as follows: “Among other things, we come from the field of radio clocks and weather stations – everything that has to do with time and weather. So the sensors and radios were already there. For mobile monitoring, however, completely different conclusions are drawn from the data supplied than, for example, with a classical thermometer. Frank Reiser gives just a few examples: “For example, if the temperature near the stove rises sharply, I can conclude that I forgot to make out a plate. Or if a water sensor near the washing machine sounds an alarm and it’s currently on, I can assume it’s overflowing.”
With motion sensors mounted on doors and windows, a mobile monitoring device is also an inexpensive alternative to the classic alarm system. When a door opens, the alarm first goes to your mobile phone and not directly to the police. “Then I can quickly let a neighbor know if everything is all right and save me an expensive police operation, should it be a false alarm.”
