The canary camera system uses a pair of blinks to detect the state of the camera and provide a quick and easy way to shut down the camera system, as well as shut off the lights, and prevent the shutter from opening.
If the canary is dead, the system can then be used to start it up again.
It can also be used in situations where there is no power supply to shut off, and to check for battery or other safety hazards.
In the event of an emergency, the canaries can be used as a remote control for the lights.
This video shows how the system works.
The canaries are small, light-up devices that can be attached to any part of a vehicle.
The first two are on the left, and the third is on the right.
They can be activated from a remote, by pressing a button, or by touching them to the screen.
The system is controlled by the canarians’ eyes.
