2. 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.Wireless Security Camera
After many months of reviewing different cameras from top brands like Arlo and Canary, I’m ready to show you the best security cameras of 2019. I love the Nest Cam Indoor— obviously, or I wouldn’t have named it my best camera!Video wise, the Nest Cam impresses with 1080p HD display, a wide 130 degree field of view and the ability to zoom in eight times.

While the box said you’d be able to see for 15 feet, things got blurry for me at 10.
