The mirror effect: when self-reflection calms things down A ticket inspection on the train. A passenger raises their voice, the mood changes. Then they see themselves on the display of a NetCo Body-Cam Pro – their voice softens, the argument loses momentum. Even before recording has started.
This mirror effect has an immediate impact. People behave noticeably more calmly when they see their own behaviour. A tense situation turns into a conversation – **conflicts escalate 75% less often, according to the Duisburg Public Order Office, which has been using this solution for some time. ## Hamburg now also relies on NetCo body cams
Since August 2025, the Hamburg Hochbahn police have also been using body cams from NetCo. Initially, 21 teams were equipped, with plans to roll out the technology to all patrol teams in the future. “Experience shows that people who are filmed when behaving aggressively calm down more quickly and are easier to deal with,” confirms Hamburg’s Transport Senator Anjes Tjarks.
The first successes are already evident: the Hochbahn security service reports around 40 violent attacks each year. This year, managing director Normen Wiegand is already reporting a significant decline. ### Why body-cams now? Violence on public transport is on the rise. At the same time, there is a shortage of skilled workers in the transport sector. Body-Cams solve both problems: they protect staff and make the job more attractive.
The 3 success features of the NetCo body cam 
1. Mirror function: de-escalation through self-reflection The front display shows behaviour in real time. Aggressive passengers see themselves and calm down – often before the first recording is made.
Practical evidence: In 75% of cases handled by the Duisburg public order office, the display alone is enough to calm people down. 
2. Pre-recording: No situation is lost 60 seconds before activation, image and sound are automatically saved. This means that the entire escalation is documented – including the trigger. Legal advantage: Complete preservation of evidence for criminal proceedings and insurance claims.
### 3. GDPR compliance: Legal certainty from Germany * Red LED signal during recording * Mandatory verbal announcement
- Server location in Germany – full control over your data * Automatic deletion of recordings after 30 days Ready for use in seconds – no training required. The proven 3-step model (wear visibly → announce → record) ensures maximum transparency and de-escalation.
