当你不在家时，许多忧虑可能会开始引起你的注意.我把咖啡机关掉了吗?我锁上了门吗?孩子们在做家庭作业还是看电视?有了智能家居，你可以完全不用考虑这些担忧.
智能家庭是具有通信网络的家庭.该网络可以连接诸如灯和电视机等设备，并且可以通过电线、移动电话通信或通过因特网的WiFi来远程控制它们.
越来越多的人可能开始考虑拥有一个智能家庭，因为它使生活更方便.它可以帮助保持你的房间在一定的温度.它可以记录在家里发生的事情，并发送视频到您的手机.当你在国外度假，你可以使用智能家居控制器在必要时打开或关闭电源.一些智能家居可以接待访客，让他进来，给他喝一杯酒.他们甚至可以喂猫和给植物浇水.
此外，智能家庭的问题很容易解决.大多数智能家居技术和设备是无线的，可以通过简单的工具进行操作，只使用指导信息.当出现问题，你可以自己处理，而无需请专家过来维修.
然而，对于家庭用户，智能家庭技术远不是完美的.拥有该技术和设备可能相当昂贵.此外，因为智能家庭系统允许其所有者从任何地方获得家庭信息，所以它离开家后容易被黑客攻击，他们可能会秘密使用或更改系统中的信息.
现在，许多科学家对智能家居技术的未来感到兴奋.想象一下能从你的镜子获得时尚建议，或从你的冰箱获得食品购物建议.有些人却在担心这些智能设备会让人们懒惰和寂寞.不过有一件事是肯定的，智能家居技术将改变我们的生活和工作的方式.
