Carbon monoxide is an odorless and tasteless gas that can kill residents even when low amounts are inhaled. Instead of having both a carbon monoxide detector and a smoke detector, this unit combines the two into one unit. For the smoke detection the unit includes ionization sensing technology, which detects visible fire particles and warns of impending danger. The carbon monoxide alarm goes off if the carbon monoxide levels in your home increase to a dangerous level. The Kidde KN COSM B Battery Operated Combination Monoxide has four verbal warnings including fire, carbon monoxide, low battery and smart hush announcement. There is a voice alarm, a flashing light, along with a loud beeping sound that warns of danger.

33 x 18. 83 feet. We mounted and hardwired each of the detectors to the apparatus and noted how long it took to install each one using the included manufacturer instructions. After connecting each alarm to a Wi Fi network, we installed its associated mobile app on a smartphone. We evaluated how easy each app is to use and tested how long it takes for notifications to arrive on your mobile device when there is an emergency. We also assessed how well each device connects to third party smart home automation systems. We contacted each company, when possible, to assess how helpful its representatives are when resolving potential technical problems. Detection EfficiencyOur detection efficiency testing is for comparison purposes only and was not designed to replace industry standard safety certifications carried by each unit we reviewed. Perhaps the most important thing we learned from our testing is that smoke detectors have a limited range, which is one of the reasons modern building codes require a unit in every bedroom as well as in areas adjacent to bedrooms. To test effectiveness, we sprayed test smoke from an aerosol can directly at each device and timed how long it took the alarm to sound. We sprayed the test smoke from 5, 10 and 15 feet away.

Indoor security cameras are a great way to give yourself peace of mind when you're away from home. Not only can you check in on pets if you have them, but you can also receive notifications that'll alert you to intruders. Many cameras feature smart alert systems that can tell you about out of the ordinary sounds and motion in your household; some cameras feature both a speaker and a microphone for two way communication, and a few even come with sirens and alarms to scare away intruders. If you'd like to add an extra layer of security and safety to your household, consider picking up an indoor security camera!You can always check in on a live stream of your Nest Cam, but some features, including video history, are tied to the subscription based Nest Aware cloud service. For $10 a month, you get all the normal Nest Cam features plus a full 10 day video history, person alerts Nest not only notifies you of motion, but it can try to determine if the shape it's seeing is a person, activity zones instead of tracking motion across the entirety of its view, Nest Cam can pay attention to specific zones, and clips and time lapses if your Nest Cam captures something you've got to share, you can create downloadable video clips. The 147 degree 1080p camera offers the standard night vision and microphone — the only thing it's missing is two way audio, giving you the option to communicate with who or whatever is in your home while you're out and about.
