你不知道有这么好的安全装置
They're less common than 感烟探测器s, but these devices are worth a look.
Everyone knows about basic household protection gadgets like the 感烟探测器 和 一氧化碳 探测器, but 在这里 are five less familiar home safety devices that make it easier to get some peace of mind.
数码偷窥器
Traditional peepholes are difficult to see through, making it easier for unannounced — 和 potentially unsavory — visitors to get you to open your door. LCD peephole viewers attach over existing peepholes 和 let residents view their visitors on screens that are about the size of a digital camera's. Features can include wide angle 和 zoom modes, low-light visibility 和 image recording capability.
电视模拟器
Timed lights that come on at the same time each night may not fool burglars, 但电视闪烁的灯光可能会. Rather than leaving your TV on when you're away from home, look into LED 电视模拟器 units. These small devices use less energy than a TV but emit lights that flicker 和 change color 和 intensity, giving the appearance from outside the house that a TV is on — 和 that someone is home.
漏水报警器
When a sump pump overflows or a washing machine hose fails, you could be out thous和s of dollars in repair bills. 而不是, a wireless water leak alarm can alert you to a leak before it becomes a whole-house disaster. When they detect a leak, these devices send out a loud alarm. 要增加保护，请安装 全屋漏水检测系统 that will automatically shut off the entire water supply if a leak is detected.
会说话的烟雾探测器
You may think no one could sleep through the shrill alarm of a 感烟探测器，但你的孩子可能醒不过来. An 美国儿科学会的研究 found that just 58% of children awoke to the sound of a smoke alarm within five minutes — but half woke within 20 seconds of hearing their parents' voice. "Talking"smoke 和 一氧化碳 探测器s let parents record a message telling the child to wake up 和 what to do next.
干燥机排气压力系统传感器
久而久之，绒毛从 干衣机 accumulates in the exhaust vent, creating clogged conditions that can lead to a fire. Though annual cleanings of your exhaust vent are always recommended, a pressure system sensor can let you know when a lint clog is inhibiting air movement. These systems send out an alarm when air movement is seriously restricted in the vent, potentially giving you time to prevent a fire before it's too late.
