It can detect
smoke faster in a large area or in a room with a high ceiling or rooms subject to temperature extremes. On the other hand the ionization type smoke detector is more sensitive to flames than to smoke. It sets off an alarm faster than a photoelectric or optical beam smoke detector once it detects fire. Therefore it is best used to detect smoke from fast flaming materials like paper and wood. It is also cheaper to manufacture. Compared to photoelectric smoke detectors, it
consumes less power so a small battery can power it for month and is independent of external wiring.

Luckily, I have an old apple Time Capsule running it’s own 2. 4 Ghz network and a signal booster just inside the house – because this couldn’t see either router from 15′ away…The
really big problem I have is that even though I shared it with my wife and daughter, they can’t look at videos to see what the event was… My wife has a home business and needs to know when packages are left there, we have porch pirates come through our neighborhood from time to time.
