If you only want a small section of your Nest Cam’s field of view to be subject to motion alerts, you create “activity zones.” That way, you’ll only receive notifications when motion has been detected only in a certain area—like your driveway, for instance.
如果您只希望Nest Cam视场的一小部分受到运动警报的影响，则可以创建“活动区域”。 这样，仅当仅在某个区域(例如车道)中检测到运动时，您才会收到通知。
Most of the Nest Cam’s features can be set up from within the Nest app on your smartphone or tablet. However, activity zones can only be set up and adjusted through the Nest web interface. The only prerequisite is that you must have a Nest Aware subscription in order to have activity zones.
可以从智能手机或平板电脑上的Nest应用程序中设置Nest Cam的大多数功能。 但是，只能通过Nest网络界面设置和调整活动区域。 唯一的先决条件是您必须具有Nest Aware订阅才能拥有活动区域。
Start by heading to Nest’s website. Click on “Sign In” at the top-right corner of the screen.
首先前往Nest的网站 。 单击屏幕右上角的“登录”。
Next, click on the live view of your Nest Cam. The interface will look nearly identical to the mobile app.
接下来，单击您的Nest Cam的实时视图。 该界面看起来几乎与移动应用程序相同。
When the live view loads, click on “Zones” down in the bottom-right corner of the screen.
加载实时视图后，单击屏幕右下角的“区域”。
A pop-up will appear where you’ll click on “Create”.
将出现一个弹出窗口，您可以在其中单击“创建”。
Next, a transparent purple box will appear on the screen. The area within this box is your activity zone.
接下来，一个透明的紫色框将出现在屏幕上。 此框内的区域是您的活动区域。
Click and drag on the small circles to adjust the shape of the box, and click and hold on the box to drag it around the screen until you’re happy with its placement.
单击并拖动小圆圈以调整框的形状，然后单击并按住框将其在屏幕上拖动，直到对它的位置满意为止。
Once that’s done, you can give that activity zone a name down in the bottom-left corner of the screen, as well as change the color of the highlight.
完成后，您可以在屏幕左下角为该活动区域命名，并更改突出显示的颜色。
After that, click on “Done” in the bottom-right corner to save your new activity zone.
之后，单击右下角的“完成”以保存新的活动区域。
Your activity zone will appear in the pop-up list, where you can edit it at any time. You can also create more activity zones if you’d like. However, be sure to uncheck “Motion” so that you only receive motion alerts within your activity zone, rather than just all motion alerts in general.
您的活动区域将显示在弹出列表中，您可以随时在其中进行编辑。 您也可以根据需要创建更多的活动区域。 但是，请确保取消选中“运动”，以便仅在活动区域内接收运动警报，而不是一般的所有运动警报。
This is a great feature to have, especially if you have your Nest Cam pointed outside where passing cars can constantly trigger motion notifications. Instead, you can pinpoint where exactly you want motion alerts to be activated and only receive alerts that you actually care about.
这是一个很棒的功能，尤其是当您将Nest Cam指向外部时，过往车辆会不断触发运动通知。 相反，您可以精确定位要**的运动警报的确切位置，而只接收您真正关心的警报。
