Nicely done. @phone users who comment That nifty "reply" feature where your comment appears immediately below the comment you are replying to does not work on any other platform. As a result, your conversational reply looks like a total non sequitur to everyone else. If you want us to understand your comments you need to, at a minimum, use the @ convention. As is not unusual, pretty much with Rex here. Well done for what it is, but I'm not much in to humor that was old timey when I was young.
which is the best home security system
TAll smoke detectors use one of two types of sensors to detect fires. Ionization type sensors are best at detecting fast burning fires, while photoelectric sensors are generally better at alerting you about smouldering, or slow burning fires. You should have both types of alarms in your house. Smoke alarms such as the Nest Protect are designed to pick up both types of fires. Carbon monoxide and other gas detection. Even if you don't have a fire in your home, you can be suffocated by carbon monoxide.
