Some bus operators in the regional transport system have already installed cameras. For example the Veolia company will be placing cameras in about 100 of its vehicles this summer. Around 50 of the City's own buses carry cameras and all new buses taken into service come with surveillance cameras.

"Camera surveillance in itself prevents violent behaviour because the risk of getting caught is greater. Camera surveillance is also justified by the vandalism targeted at buses such as defacing and cutting up benches," says Ville Lehmuskoski, planning chief for Helsinki Region Transport, HSL.

According to plans, in future, each bus will carry three surveillance cameras, one of which will be focused at all times on the driver.
