One other great advantage of security cameras is they are certain that the children and seniors are monitored while youre away.

Smart thermostats： Neither thermostat needs a C-wire7， but there are a number of caveats8. Some intelligent thermostats may also tap into door and window sensors in addition to the motion sensors for your house security system. There are a couple of prominent smart thermostats for low voltage heating systems available on the market today.

Bright thermostats are normally very simple to install， but its important that you know the way your system is wired before you begin. They have plenty of upsides9.

智能家居有許多方便供用的常見設備。其中一些設備可歸入四類必需品，即智能照明、溫度控制、娛樂休閑和最為重要的家庭安保設備。

智能照明：智能燈是家中最常用的設備，易于安裝和使用。這種設備在家中必不可少，它還有定時、動作感應及調度等功能。

有了智能照明系統，人們就可以非常容易地控制室內整體照明。如果房主想在一天當中特定時間開關燈，坐在家里任何一處，無須走動便可輕易辦到。

智能照明系統有助于提高睡眠質量。它專為臥室定制，可以幫助克服光線導致的不眠癥。通過模仿太陽，其光線可從清晨刺眼的短波藍光過渡到日落時的柔光，從而降低入睡難度，幫助人體輕松進入睡眠狀態。

安全攝像頭：你也許知道百萬像素安全攝像頭一些很棒的附加功能。與固定攝像頭相比，云臺攝像頭的優勢在于可覆蓋更多區域。安全攝像頭的另一大優點是它可以確保你在外出時監控到家中的老人和孩子。

智能恒溫器：恒溫器無須接入公共端導線，但有很多地方需要注意。在家庭安保系統中，除動作感應器外，一些智能恒溫器還能與門窗感應器相連。一些性能優越的智能恒溫器現已上市，可用于低電壓供暖系統。

智能恒溫器安裝通常很簡單，但安裝前要了解系統工作原理，這一點很重要。智能恒溫器有許多優點。無論如何，它總會知道何時調節溫度，時刻給你呵護。因為這就是它的用途所在——節省開支。智能恒溫器價格有可能比程控恒溫器更高。如果考慮價格因素，程控恒溫器或是一個合適選擇。你可以用智能手機、平板電腦或計算機來控制房內溫度。安裝一臺無線智能恒溫器，不僅可以降低能耗費用，還能常年保持房內舒適。

地理圍欄技術使用手機定位服務，恒溫器得以隨時感知到你進入或離開家中某個數控區域。大多數智能恒溫器都能提供某種形式的用戶跟蹤。

智能娛樂設備：如果想把所有設備連接到一起，三星公司的“智能家居中心”是目前的最佳選擇，因為它可以連接很多產品，準備和使用過程也非常簡單。這些產品包括智能音箱、智能電視，甚至還有智能投影儀。
