# Browser call controls and device settings Choose call devices, mute audio or video, place a call on hold and use permitted camera backgrounds. *Release 3.3 · admin, operator, visitor* **Settings › General Settings › Video Chat** ## What it is Browser call controls let you mute your microphone, turn your camera off and choose available devices. Operators can put the call on hold and resume it. Background and layout options depend on the website setup, browser and provider. ## Who uses it and why - Operators choose devices, manage their camera and microphone, and hold or resume calls. - Visitors control their own microphone, camera and available devices. - Administrators ask Powerfront to set the website's camera, background and browsing rules. ## Where to find it Use the microphone, camera and hold icons in the browser call window. Open the call's **Settings** for **Select Camera**, **Select Microphone**, **Select Speaker** and **Mirror my video**. Powerfront manages website defaults at **Settings › General Settings › Video Chat**, under **Visitor** and **Operator**. ## How it works Use the microphone or camera control to change what the other participant can hear or see. INSIDE communicates these states to the other participant. Turning off a camera does not itself end the call. To change a device, open the call's **Settings**, choose an available device and select **Save**. **Cancel** closes the changes. Device lists depend on what the browser can access. An operator can place the call on hold and resume it later. The call displays **Call on hold...** while held. Recorded hold duration counts time within an established call, excluding time before connection and after the call ends. Where permitted and supported, you can preview your camera and use background blur or a replacement image. A placeholder shown while the camera is off is separate from a replacement background applied to live video. ## Configure it Ask Powerfront to set camera behaviour separately for **Visitor** and **Operator**. **Voice Only** prevents camera video for the selected participant; **Camera is off at start of Chat** starts with the camera disabled without making it permanently unavailable. Powerfront can set **Allow Changing Background Image**, **Default Background Image (Video)** and **Operator Placeholder Image**. The recommended operator replacement image is landscape, at least 1280 by 720 pixels; the placeholder recommendation is at least 340 by 460 pixels. Powerfront can also change portrait cropping, video size and browsing restrictions. You can choose your available call devices directly in the call window. ### Settings | Setting | Where | Applies to | Default | Who can change it | What it does | |---|---|---|---|---|---| | Voice Only | Settings › General Settings › Video Chat › Visitor | website | Off | Powerfront, on request | Restricts visitors to audio without camera video. | | Voice Only | Settings › General Settings › Video Chat › Operator | website | Off | Powerfront, on request | Restricts operators to audio without camera video. | | Camera is off at start of Chat | Settings › General Settings › Video Chat › Visitor | website | Off | Powerfront, on request | Starts visitors with their camera off. | | Camera is off at start of Chat | Settings › General Settings › Video Chat › Operator | website | Off | Powerfront, on request | Starts operators with their camera off. | | Start with Back Camera | Settings › General Settings › Video Chat › Operator | website | Off | Powerfront, on request | Starts the operator with a rear-facing camera where the device supports it. | | Allow Changing Background Image | Settings › General Settings › Video Chat › Visitor | website | Off | Powerfront, on request | Allows visitors to change their video background.

Check browser camera permission and ask Powerfront to check whether the website has set your participant type to **Voice Only**. ### Why does the visitor see an image instead of my camera? Your camera may be off. A configured **Operator Placeholder Image** is shown in that state. ### Why is there no background selector? Background changes must be allowed for your participant type and supported by your browser and call provider. Ask Powerfront to check the website policy. ### How do I use a different microphone? Open the call's **Settings**, choose **Select Microphone**, then select **Save**. ### Does turning my camera off end the call? No. Camera mute and ending the call are separate controls.
