There are many common devices in a smart home available for use. But some gadgets1 fall into four categories which are essential. These are smart lighting， climate control， entertainment purpose and most important security of your home.

Smart lighting： Smart light bulbs are the most commonly used devices at home. It is very easy to install and use. Without a smart light bulb， a home is incomplete. This device offer advantages such as timers， motion-sensing capabilities as well as schedulers2.

With a smart light bulb system， it is very easy to control the total lighting system of a house. If a homeowner wants to switch the light on and off at certain times of day they can do it very easily by sitting anywhere at the house without moving.

Smart lighting system helps to sleep well. It is created specifically for bedrooms， to overcome the problems of light-induced wakefulness3. It reduces the difficulty by mimicking the sun， transitioning its light from the stimulating blue wavelengths4 of early morning light to soothing light of evening sunsets. It helps the human body to sleep easily.

Security camera： Maybe you know of some exciting added benefits of megapixel5 security cameras. The advantage of PTZ6 security cameras is they can cover more area when compared with fixed security cameras. 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. Irrespective of10 the reason， a wise thermostat never forgets， always knows how to change your temperature， and always cares because thats exactly its purpose which is the way that it saves you money. Intelligent thermostats also have a tendency to be more costly than programmable models， so if the price is a factor a programmable thermostat may be right for you. They allow you to control the temperature in your home with a smartphone， tablet， or computer. Installing a Wi-Fi-enabled smart thermostat can decrease energy expenses and help keep your house comfortable year-round.

Geofencing11 uses your phones location services to permit the thermostat to know whenever you have entered or exited a digital perimeter around the home. Most smart thermostats offer you some kind of user tracking.

They consist of smart speakers， smart televisions， and even smart movie projectors.

Theyre so simple now that just about anyone can take advantage of home automation to simplify their lives and enjoy.

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

智能照明：智能燈是家中最常用的設(shè)備，易于安裝和使用。這種設(shè)備在家中必不可少，它還有定時(shí)、動(dòng)作感應(yīng)及調(diào)度等功能。

有了智能照明系統(tǒng)，人們就可以非常容易地控制室內(nèi)整體照明。如果房主想在一天當(dāng)中特定時(shí)間開關(guān)燈，坐在家里任何一處，無(wú)須走動(dòng)便可輕易辦到。

智能照明系統(tǒng)有助于提高睡眠質(zhì)量。它專為臥室定制，可以幫助克服光線導(dǎo)致的不眠癥。通過(guò)模仿太陽(yáng)，其光線可從清晨刺眼的短波藍(lán)光過(guò)渡到日落時(shí)的柔光，從而降低入睡難度，幫助人體輕松進(jìn)入睡眠狀態(tài)。

安全攝像頭：你也許知道百萬(wàn)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(tái)攝像頭的優(yōu)勢(shì)在于可覆蓋更多區(qū)域。安全攝像頭的另一大優(yōu)點(diǎn)是它可以確保你在外出時(shí)監(jiān)控到家中的老人和孩子。

智能恒溫器：恒溫器無(wú)須接入公共端導(dǎo)線，但有很多地方需要注意。在家庭安保系統(tǒng)中，除動(dòng)作感應(yīng)器外，一些智能恒溫器還能與門窗感應(yīng)器相連。一些性能優(yōu)越的智能恒溫器現(xiàn)已上市，可用于低電壓供暖系統(tǒng)。

智能恒溫器安裝通常很簡(jiǎn)單，但安裝前要了解系統(tǒng)工作原理，這一點(diǎn)很重要。智能恒溫器有許多優(yōu)點(diǎn)。無(wú)論如何，它總會(huì)知道何時(shí)調(diào)節(jié)溫度，時(shí)刻給你呵護(hù)。因?yàn)檫@就是它的用途所在——節(jié)省開支。智能恒溫器價(jià)格有可能比程控恒溫器更高。如果考慮價(jià)格因素，程控恒溫器或是一個(gè)合適選擇。你可以用智能手機(jī)、平板電腦或計(jì)算機(jī)來(lái)控制房?jī)?nèi)溫度。安裝一臺(tái)無(wú)線智能恒溫器，不僅可以降低能耗費(fèi)用，還能常年保持房?jī)?nèi)舒適。

地理圍欄技術(shù)使用手機(jī)定位服務(wù)，恒溫器得以隨時(shí)感知到你進(jìn)入或離開家中某個(gè)數(shù)控區(qū)域。大多數(shù)智能恒溫器都能提供某種形式的用戶跟蹤。

智能娛樂(lè)設(shè)備：如果想把所有設(shè)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?yàn)樗梢赃B接很多產(chǎn)品，準(zhǔn)備和使用過(guò)程也非常簡(jiǎn)單。這些產(chǎn)品包括智能音箱、智能電視，甚至還有智能投影儀。

這些智能設(shè)備操作非常簡(jiǎn)單，任何人都能通過(guò)家居自動(dòng)化來(lái)簡(jiǎn)化并享受生活。
