Combination alarms run on AA batteries and cost around US$23 each. 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.

UPDATE 02/10/2017: It has come to my attention that this is a pretty wordy and long review. I'm sure not everyone is interested in, for instance, the things that I tried that didn’t work. Fair enough. For the convenience of those that would like to skip over those unnecessary details, after you read the sentence that begins with “The biggest issue I have had,” skip ahead to where you see SOLUTION. Pros:The daytime video on this thing is excellent and the color night vision is phenomenal. Physical set up was a breeze.
