# Graffiti Prevention Graffiti Alarm Detector By Pearl | Published 2008-09-16 | Unique Source: Trend Hunter, https://www.trendhunter.com/trends/graffiti-prevention-graffiti-alarm-detector References: [newscientist](http://www.newscientist.com/blog/invention/2008/09/graffiti-alarm-system.html) Graffiti is unsightly and is impossible to remove if it is not paint based but etched into perspex. Usually the whole perspex piece would have to be removed and replaced which is costly. To prevent such vandalising, a new graffiti alarm system has just been patented. Invented by Seng Chu Tan and his team at Curtin University of Technology in Perth, Australia, the graffiti alarm system detects the noise of someone etching via the microphones on the surface of the material. The [microphones are connected to a computer](https://www.trendhunter.com/trends/venting-machine) which can identify the correct sounds of someone carving rather than background noise. An alarm then sounds and authorities are also notified. Of course, if you LIKE graffiti, we've got many [inspiring pieces of work](https://www.trendhunter.com/trends/art-by-squares) to show you how to do it: ## Trend Insights (Trend Hunter) - Score: 2.7/10 - Popularity: 9% | Activity: 63% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Unique](https://www.trendhunter.com/unique) > [Inventions](https://www.trendhunter.com/inventions) ## Key Themes ### What's Driving This Trend - **Graffiti Detection Technology:** Developing technology to detect and prevent graffiti vandalism can help save costs involved in replacing damaged surfaces as well as reducing the amount of unsightly graffiti in public spaces. - **Smart Surveillance Systems:** Incorporating AI and other smart technologies into surveillance systems for public spaces can provide real-time alerts to authorities regarding incidents like graffiti vandalism and aid in their prevention. - **Digital Graffiti Art:** Encouraging the creation of digital graffiti art that can be edited or removed without causing damage to public spaces can be a disruptive innovation opportunity in the urban art scene. ### Who This Affects Most - **Security Systems:** Incorporating this graffiti alarm system into existing security systems can enhance the level of security and reduce the impact of graffiti vandalism in public areas. - **Urban Planning and Development:** Working with individuals and groups within the urban art community to identify areas in public spaces that can be designated for graffiti art can help reduce the number of unsightly vandalism while also promoting engagement and creativity within the community. - **Construction and Architecture:** Developing new building materials that can resist or be easily fixed after graffiti vandalism can help reduce the cost and effort involved in replacing damaged surfaces while also promoting long-term sustainability. ## Related on Trend Hunter - [Decorative Removable Paints](https://www.trendhunter.com/trends/glasst.md) - [Parcel Delivery Alarm Systems](https://www.trendhunter.com/trends/package-protector.md) - [Digital Graffiti NFTs](https://www.trendhunter.com/trends/graffiti-wall-collection.md) - [Artist Protection Tools](https://www.trendhunter.com/trends/artist-protection.md) - [AI-Powered WiFi Security Systems](https://www.trendhunter.com/trends/home-security-alarm-system.md) - [Pocket-Sized Safety Locks](https://www.trendhunter.com/trends/gaze.md) - [Enigmatic Graffiti Incidents](https://www.trendhunter.com/trends/enigmatic-graffiti.md) - [Novel Home Security Concepts](https://www.trendhunter.com/trends/home-security-concept.md) - [Alarm-Equipped Laptop Locks](https://www.trendhunter.com/trends/antitheft-laptop-device.md)
