'The safety of others has always been a matter close to my heart', says Hans Wetzlar, Managing Director of Ihre Sicherheit Security Service in Bielefeld. It was out of this motivation that he founded his security company ten years ago. Together with his team, he ensures, for example, that visitors to events and trade fairs can move around safely. Mobile 'video guards', using Dahua's powerful video surveillance technology, are now contributing to this.
