Typically, smoke detectors have two standard parts that they are made up of; a sensor, or detector, which identifies smoke, and an electronic horn that emits a loud blast to alert residents. Photoelectric detectors and ionization detectors are the two main types of smoke detectors available on the market and are usually equipped to be powered by either a battery or from the house current.
Photoelectric detectors often have miniature cameras as well that are used to detect fire.
