The Nest Cam is a simple-to-use security camera for everyone. However, if you’ve got one laying around, you can use it for a lot more than deterring criminals. Here are some uncommon, but useful things you can do with your Nest Cam.
Nest Cam是适合所有人的易于使用的安全摄像机 。 但是,如果周围有一个地方,那么它可以比阻止犯罪分子更多地使用。 您可以使用Nest Cam进行一些不常见但有用的操作。
注意包裹的运送 (Watch for Package Deliveries)
Amazon might give you an anxiety-inducing tracker to tell you when your package arrives, but you’d feel better getting expensive stuff delivered to your door if you could see it for yourself. Point a Nest Cam outside your door and you can see when your packages arrive. Once it shows up, you can check your camera from work to make sure it’s safe, undamaged, and not stolen.
亚马逊可能会为您提供引起焦虑的跟踪器,以告诉您包裹何时到达,但如果您能亲眼看到,则最好将昂贵的物品运到门口。 将Nest Cam对准门外,即可看到包裹何时到达。 出现后,您可以检查工作中的相机以确保其安全,完好且未被盗。
You can also set up Nest Cam to send you a notification when it detects motion (like your package being delivered). Open your Nest app and turn on notifications in Settings. You can choose to only send notifications when you’re not home, or any time. Subscribers who pay for Nest Aware can even set up Activity Zones to watch a specific part of the camera for movement. If you want to make sure your stuff isn’t sitting out for longer than necessary, this is incredibly handy.
您还可以将Nest Cam设置为在检测到运动(例如包裹递送)时向您发送通知。 打开您的Nest应用 ,然后在“设置”中打开通知。 您可以选择仅在不在家或任何时候发送通知。 支付Nest Aware费用的订户甚至可以设置活动区域,以观看摄像机的特定部分进行移动。 如果您想确保自己的东西摆放的时间不长于必要,这非常方便。
照看你的宠物 (Keep An Eye On Your Pets)
You love your adorable little ball of fur, but every hour you’re away from home (and half the ones you aren’t), you know they could be destroying something. Or peeing on something. Or eating something they’re going to puke up later. You might not be able to stop everything they do, but it would at least make you feel better to know when it’s happening, or which pet did the destroying. Nest Cams can help with that.
您喜欢可爱的小皮毛球,但每个小时出门在外(不是您的一半),您都知道它们可能会破坏某些东西。 或撒尿。 或者吃些他们以后会吐出来的东西。 您可能无法阻止他们所做的一切,但这至少会使您更好地知道它的发生时间或破坏的对象。 Nest Cams可以帮助您。
While you’re at work or on vacation, Nest Cams can show you a live feed of what your pets are up to in your home. You can also view snapshots of recorded video whenever motion is detected from up to three hours prior. If you subscribe to Nest Aware, however, you can watch up to 30 days worth of video history. That should give you plenty of evidence to suss out whether Fido, Fluffy, or War Machine is destroying your throw pillows.
当您在工作或度假时,Nest Cams可以向您实时显示您的宠物在家里做什么。 您也可以在最多三个小时之前检测到运动时查看录制的视频的快照。 但是,如果您订阅Nest Aware ,则最多可以观看30天的视频历史记录 。 那应该给您足够的证据来证明Fido,Fluffy或War Machine是否正在破坏您的枕头。
外出时与孩子交谈 (Talk to Your Kids While You’re Away)
You might not need to start a conversation with someone who’s trying to break into your house. However, if you’ve got your Nest Cam set up indoors, you’re more likely to catch your kids throwing stuff in the house, or sneaking into the liquor cabinet. If that happens, you can use the speaker on the Nest Cam to talk to the people in your house, just to let them know you’re listening.
您可能不需要与试图闯入您的房屋的人开始对话。 但是,如果您将Nest Cam设置在室内,则您更有可能会抓住孩子们在屋子里扔东西或溜进酒柜的麻烦。 如果发生这种情况,您可以使用Nest Cam上的扬声器与您家中的人交谈,只是让他们知道您在听。
When you log in to watch your camera feed on the web or mobile app, you can see a microphone button. Click this (or tap and hold on your phone) and you can speak through the camera in your home. The speaker quality isn’t that great, but it’s enough to get a simple “I wouldn’t do that, if I were you” through to the kids to let them know you’re watching.
登录并在Web或移动应用程序上观看相机Feed时,您会看到一个麦克风按钮。 单击此按钮(或点击并按住手机),即可通过家中的摄像头讲话。 扬声器的质量不是很好,但是足以让孩子们简单地告诉他们,“如果我是你,我不会那样做”,让他们知道您在看。
将相机用作其他智能小工具的运动检测器 (Use Your Camera As a Motion Detector For Other Smart Gadgets)
Nest Cams wouldn’t be worth much if they weren’t smarter than your average webcam. Fortunately, they are. As we’ve touched on before, your Nest cam can notify you when it detects sound or movement. You can also use that trigger to control all the other smart gadgets in your house using IFTTT and its powerful big brother Stringify.
如果Nest Cams不比您的普通网络摄像机更智能,那么它们的价值就不会很高。 幸运的是。 如前所述,您的Nest凸轮可以在检测到声音或运动时通知您。 您还可以使用该触发器, 通过IFTTT及其强大的哥哥Stringify来控制房屋中的所有其他智能小工具。
The Nest Cam IFTTT channel and Nest Stringify Thing can use detected motion or sound from the Nest as triggers for their automation (and Stringify can also be activated by Nest’s person-detection feature). You could use that trigger to turn on your living room lights when you come home, log every suspicious movement or sound from your security camera, or even fake a barking dog through your Sonos speaker to scare someone away. Sure, that last one might sound a bit like overkill, but if you want to make your home as smart as possible, you can do a lot more with a Nest Cam than just look through it.
Nest Cam IFTTT频道和Nest Stringify Thing可以将Nest中检测到的运动或声音用作其自动化的触发器(Stringify也可以通过Nest的人员检测功能**)。 您可以使用触发器在回家时打开客厅的灯 , 记录安全摄像机中的所有可疑动作或声音 ,甚至可以通过Sonos扬声器伪造吠叫狗来吓someone某人。 当然,最后一个听起来可能有点过头,但是如果您想让自己的家尽可能的聪明,那么使用Nest Cam可以做更多的事情,而不仅仅是浏览它。
