A carbon monoxide detector triggers when the level of carbon monoxide in your home reaches a dangerous level. Unlike other environmental dangers, you cannot see, taste, or smell carbon monoxide. These detectors can save your life and those of your pets. Carbon monoxide is released when you burn gasoline, wood, oil, charcoal, propane, and natural gas, so homes with gas appliances, chimneys, wood burning stoves, and connected garages have a higher need for carbon monoxide detectors. Like smoke and fire alarms, these sensors can work as stand alone alarms or connect with your security system. It’s always a great idea to connect detectors to your system so that a monitoring center can notify you and emergency dispatch in case the alarm is triggered. Some wireless home security systems offer a video recording storage option and others don’t. For the ones that don’t, you are able to see a live video feed of your home any time you access your system; however, nothing is recorded. The systems with video storage generally include either a local storage or cloud storage option. A local storage option saves a pre determined number of video clips on the device itself. This option is usually cost free.
