Intelligent wall to catch sprayers
Graffiti causes damage amounting to 200 to 500 million euros every year throughout Germany. In a pilot project, Vodafone has developed a solution to prevent illegal graffiti. Together with the company Hyve, a wall was created that smells sprayers and sounds the alarm.
The Federal Criminal Police Office recorded over 100,000 cases of damage to property caused by illegal graffiti in 2016. The solution from Vodafone and Hyve should now put an end to this vandalism.

Among other things, a sensor detects the tiny particles of graffiti paint. If an uninvited painter begins his work, the sensor sounds an alarm and sends it directly to a control center via Narrowband IoT - Vodafone's machine network. From here, security forces can be alerted and deployed. To deter perpetrators before they even start painting, the sensor can also trigger an alarm directly on site.
A network especially for machines
"Narrowband IoT is our network specifically for machines. We use it to make the Internet of Things suitable for the masses. It is optimized for the cost-effective networking of billions of objects. Almost everything can be networked - from the garbage can to the water meter to the wall that can smell graffiti sprayers," says Dr. Eric Kuisch, Managing Director Technology at Vodafone. Narrowband IoT even transmits data in places where mobile communications would otherwise be difficult to reach: behind thick house walls and underground. Graffiti painting could even be prevented in deep train tunnels. The machine network is an optimized version of LTE. The sensors' extremely long battery life of up to ten years makes it possible to operate the alarm systems without an external power supply.
'IoT Future Labs' as a testing ground
The Alarm System 4.0 was developed in the 'IoT Future Lab', a laboratory for smart solutions in the Internet of Things, which Vodafone opened in February 2017. Here, the Düsseldorf-based telecommunications group is working with partners along the entire value chain on solutions for the Internet of Things. New applications in the machine network can be tested and further developed here under everyday conditions.
