The two types of smoke detection technologies are ionizing smoke detectors and photoelectric smoke detectors. Ionization smoke detectors detect disruptions in ion flow due to smoke, which makes them best for detecting flaming fires. Photoelectric smoke detectors use light to detect smoke, which makes them best for smoldering fires. There are also combination detectors which combine both types of technologies.

Yes, some cameras have built-in analytics that allows them to recognize the visual behavior of smoke and fires. This can be useful for outdoor applications where traditional smoke detectors can’t be used. They are also ideal for large spaces with high ceilings where smoke or heat would take long to reach smoke detectors in order to trigger them.

No, smoke detectors don’t typically detect carbon monoxide, even though it can be present in smoke. There are, however, some detectors that can detect both smoke and carbon monoxide gas, thus providing enhanced safety by being able to alert to both hazards.

No, traditionally, smoke detectors are not able to detect vape, but there are other sensors that you can invest in that do address vaping, such as HALO Smart Sensors. These sensors can also be integrated with your VMS and are especially useful for educational institutions that would like to enforce their no-vaping policies.

Smoke detectors should not be detecting steam, as they are only designed to recognize smoke particles and other products of combustion. Steam should therefore not trigger fire alarms unless there are other particles or substances present in the steam. 

No, smoke detectors cannot detect gas leaks. In order to detect gas, you will need a gas detector that is specifically designed to respond to gasses such as carbon monoxide, natural gas, propane, etc.
