Did NASA invent smoke detectors?
Further, NASA did not invent the smoke detector. NASA’s connection to the modern smoke detector is that it made one with adjustable sensitivity as part of the Skylab project. The device was made commercially available by Honeywell.

How did the early fire alarm boxes work?
One man would crank the handle that was attached to the box, releasing the key to send out a message to the central alarm station. The telegrapher at the central station would then send out the address of the location to the fire department. By the late 1800s, the electric fire alarm system was invented.
When did smoke detectors become common in homes?
The Life Safety Code (NFPA 101) was passed by the NFPA in 1976, and was the first document that stated “smoke alarms are required” to be in every home. By 1980, an estimated 50% of all homes in the U.S. reported having working alarms. That number jumped to 75% by 1984.

After locating the smoke detectors that are candidates for a camera, visually inspect the smoke detector and look for a small black dot and pinhole openings that provide the lens with perspective and a visual window. Like any camera lens, it will reflect and have a distinct visual appearance.
