Halt-Stream / Warning triangle


When vehicle breaks down, drivers have to risk their life to place the warning triangle to a long distance and might got hit without any witness.
As a solution, we’ve designed a inflatable warning sign with 360° camcorder, which can be ejected to a remote distance.
The inflatable warning sign is stored inside a sphere shell, and is placed in the projector, the whole device could be mounted on the vehicle and used as an ordinary dash-cam.
When accident happened, users can simply eject the sphere and the warning sign inside it will start to inflate itself. Once it’s done, the camcorder will then record the surroundings as evidence.
