A smoke detector does not necessarily need to look like one. Lento by Jalo is camouflaged as a fly on the wall, or even better at the ceiling. With the glue tape, Lento can be mounted in seconds only, the complete casing works as button for the alarm test or to mute in case of alarm. The Finnish design proves that technology doesn’t always need to present itself seriously, but can also come in an unusual form. Different colors and patterns complete the offering.
