If you commit to a three year contract, the price of the Nest service drops to $19 per month. Ring's Protect Plus plan goes for $10 per month and doesn't require a contract. Monitoring for professionally installed
systems tends to be more expensive. The ADT Pulse monitoring service starts at $28. 99 per month and requires a three year contract, but you also have to figure in the cost of things like hardware components, cellular backup, and installation. When we reviewed the Pulse system, our upfront cost was more
than $3,000, with a monthly fee of over $60.

It is best that homeowners are able to see the difference among these different types and see how they work, before deciding on which ones to buy and install in the house. The type of sensor installed in a smoke detector may also dictate the price range, since there are sensors that have more expensive components than those of the other types. Among the types of sensors presently used by several manufacturers of smoke detectors are the ionization type, the optic sensor – also called photo electric sensor, the air sampling sensor, and combination type sensors. A smoke detector with an ionization type sensor uses what is called radio isotopes that produce ionization in the air. The process is quite technical, but what this type of detector contains is ionized air
molecules in a chamber
inside the device. The ionized air carries electrical current and maintains that current, until something disrupts the air molecules.
