LG has announced a wrist-worn device designed to let parents keep track of where their child is and listen to what they are up to.
The Kizon uses GPS and wi-fi signals to identify the wearer's location and sends the information to an Android app.
LG is targeting the device at families with pre-school and primary school children.
However, others have raised concerns about the idea.
"A parent should never solely rely on a device alone. This will only give a false sense of security," said Peter Bradley, director of services at the charity Kidscape.
"Children still need to be taught about dangers - particularly 'stranger danger'."
"There are ethical points to consider too - should a child be able to be traced as part of going about their daily lives? How can a child develop their own coping strategies knowing a parent is watching over them?"
