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.
