chrome修改攝像頭權限

Google Chrome lets you manage which individual sites can have access to your microphone and camera. If you don’t see any video or the mic isn’t picking up voice, you might need to change the permissions Chrome is giving to a site. Here’s how.

Google Chrome瀏覽器可讓您管理哪些站點可以訪問您的麥克風和攝像頭。 如果您沒有看到任何視頻，或者麥克風沒有接聽聲音，則可能需要更改Chrome授予網站的權限。 這是如何做。

如何在Chrome中更改網站的權限 (How to Change a Site’s Permissions in Chrome)

For security purposes, Chrome prompts you any time a site requests access to your microphone or webcam. If you accidentally clicked “Block” the first time you saw the prompt, or you just want to revoke the permissions you previously gave, we’ll show you how to manage those settings.

為了安全起見，當網站請求訪問您的麥克風或網絡攝像頭時，Chrome會提示您。 如果您在第一次看到提示時不小心單擊了“阻止”，或者您只是想撤消先前授予的權限，我們將向您展示如何管理這些設置。

Knowing how and where to access the settings related to a site’s permissions to your computer’s hardware is important in case you ever need to change your mind as to what a website is allowed to use.

萬一您需要就允許使用什么網站改變主意，知道如何以及在何處訪問與網站對計算機硬件的權限相關的設置非常重要。

There are basically two ways to manage the permissions for microphone and webcam to a site: from the Omnibox or inside Chrome’s settings.

基本上有兩種方法可以管理對網站的麥克風和網絡攝像頭的權限：從多功能框或在Chrome的設置中。

從多功能框更改網站的權限 (Change a Site’s Permissions From the Omnibox)

This method works when you’ve already set the permissions for the microphone or camera and want to change them while visiting that particular site.

當您已經設置了麥克風或攝像頭的權限，并想在訪問該特定站點時更改它們的權限時，此方法有效。

Go to the website for which you want to change the permissions and click the lock icon on the leftmost side of the Omnibox.

轉到要更改其權限的網站，然后單擊多功能框最左側的鎖定圖標。

From the menu that appears, click either the microphone or camera, then from the drop-down menu, select “Allow” or “Block,” then click the X to save your changes.

在出現的菜單中，單擊麥克風或攝像頭，然后從下拉菜單中選擇“允許”或“阻止”，然后單擊X保存更改。

After saving your decision, you will have to reload the page for the changes to take effect.

保存您的決定后，您將必須重新加載頁面以使更改生效。

When a site has access to your microphone or camera, an icon will appear in the Omnibox on the right side. If you click this icon, you can choose always to block access or to continue allowing the site to have access. Again, you must reload the page for any changes to take effect.

當站點可以訪問您的麥克風或攝像頭時，右側的多功能框中將出現一個圖標。 如果單擊此圖標，則可以選擇始終阻止訪問或繼續允許站點具有訪問權限。 同樣，您必須重新加載頁面才能使所有更改生效。

如何從Chrome設置中查看權限 (How to View Permissions From Chrome Settings)

To view your microphone and camera permissions from Chrome’s settings, click the menu icon, and then click on “Settings.” Alternatively, you can?type chrome://settings/?into the Omnibox to go directly there.

要通過Chrome的設置查看您的麥克風和攝像頭權限，請點擊菜單圖標，然后點擊“設置”。 另外，您也可以在多功能框中輸入chrome://settings/ ，以直接轉到此處。

Once in the Settings tab, scroll down to the bottom and click on “Advanced.”

進入“設置”標簽后，向下滾動到底部，然后點擊“高級”。

Scroll down a little bit more until you see “Content Settings.” Click on it.

向下滾動一點，直到看到“內容設置”。 點擊它。

Once inside Content Settings, click on either? “Microphone” or “Camera” to adjust its permissions.

進入“內容設置”后，單擊“麥克風”或“相機”以調整其權限。

Although you can’t manually add a site to the allow or block list from Settings, you can see a list of every site you’ve allowed or denied access to on this page. Then to remove items you’ve previously allowed or blocked access, all you have to do is click the trash can icon next to a site.

盡管您無法從“設置”中將網站手動添加到“允許或阻止”列表中，但是您可以在此頁面上看到允許或拒絕訪問的每個網站的列表。 然后，要刪除您之前允許或禁止訪問的項目，只需單擊站點旁邊的垃圾桶圖標即可。

After you’ve removed a site from either list, the next time you go to the site, you will be prompted for permission to access the microphone or camera when the site requests it again.

從任一列表中刪除站點后，下次訪問該站點時，當該站點再次請求它時，系統將提示您訪問麥克風或攝像頭的權限。

While you can’t have Chrome globally deny—or grant, for that matter—all access to your camera and microphone but if you’d instead not be prompted to make a decision, head back to either “Microphone” or “Camera” in Chrome’s Content Settings.

雖然您無法讓Chrome在全球范圍內拒絕(或為此授予)所有對相機和麥克風的訪問權限，但是如果不提示您做出決定，請返回到“麥克風”或“相機” Chrome的內容設置。

While you’re back in this menu, toggle “Ask Before Accessing” to the off position. Although this isn’t recommended, you won’t be prompted to allow or deny a website’s access to your microphone and camera until you toggle this switch back on.

當您返回此菜單時，將“訪問前詢問”切換到關閉位置。 盡管不建議這樣做，但除非重新打開此開關，否則不會提示您允許或拒絕網站訪問麥克風和相機。

This method acts as a slight loophole to never granting access without actually denying anything.?From now on, you will no longer receive a prompt when a site requests access to your device. To receive prompts again, go back into the settings panel and re-enable “Ask Before Accessing.”

此方法充當一個漏洞，可以在不拒絕任何訪問的情況下從不授予訪問權限。 從現在開始，當站點請求訪問您的設備時，您將不再收到提示。 要再次收到提示，請返回到設置面板，然后重新啟用“訪問前詢問”。
