Since ionization type smoke detectors can detect particles smaller than smoke particles, they are prone to false alarms. Ionic smoke detectors use a radioactive isotope americium 241, and rules on proper disposal vary in each region. Some European countries have banned ionic smoke detectors. Most photoelectric smoke detectors run on AC power circuits meaning the users have to install the wirings around the house. Such smoke detectors also have a backup battery aside from the 120 volt power it needs to function. Smoke detectors should be placed where smoke isn’t supposed to be. Avoid installing them in kitchens or rooms that have steams like saunas and bathrooms to prevent false alarms. Do not install smoke and carbon dioxide detector in breezy and ventilated areas like in front of electric fans, air conditioners, windows and doors. They may pick up smoke that originated in other places or the fresh air might obscure the reading, preventing the device from setting off when it should. Install them on a high wall or in the ceiling because smoke and fire rises. What if you have a big house and there’s a fire starting somewhere in the basement and you’re asleep in your bedroom on the third floor?Fortunately photoelectric smoke detectors can be interconnected, meaning if a smoke detector sets off in the basement, all smoke detectors in the residence would alarm.

And I kind of had to speak loudly to get its attention in a room with an air conditioner. Which meant that the upstairs one heard me, too. But, hey, it plays music.

You can use the mobile app to customize the video quality to optimize camera performance or save storage space. This is an especially helpful feature that isn't in every security camera. The audio quality on this camera doesn't compare well with the competition, but is clear enough when using the two way audio function.
