> Connect cameras and link them to microphones for automatic switching.

Connect your cameras to the Director 4K, then link them to microphones so SmartSwitch can follow the conversation.

## Connect your cameras

Many mirrorless cameras, camcorders and studio cameras work with the Director 4K. They need a *clean HDMI* output, which sends the picture without menus or information overlays. You can usually find this setting in the camera’s HDMI display options.

Connect each camera to an **INPUT** port on the back of the Director 4K.

Under **Settings → Video**, open the camera’s source and choose **Camera** as its type.

## Configure SmartSwitch

A **shot** is a camera view that SmartSwitch can choose during the show. In the camera’s settings, open the default shot and enable **SmartSwitch**.

Under **Linked microphones**, select the microphones of the people visible in the shot. SmartSwitch can then show that shot when one of them speaks.

SmartSwitch continuously optimizes three criteria: showing the people relevant to the conversation (current or recent speakers), limiting visual fatigue or boredom (rhythm), and respecting your preferences (shot weights). The result is more nuanced directing than a simple “voice follower”.

Use **How often it appears** to favor a shot when several can show the person speaking.

[Start a session](/en/record-a-show#start-the-session) and speak into each microphone to see SmartSwitch choose a camera view.

## Set the frame rate

The **frame rate**, measured in frames per second (*fps*), sets the show’s video cadence. Prefer the same rate as your cameras’ HDMI output.

<accordion-item label="How can I turn cameras on automatically?">

Power your cameras with their AC adapters, then plug the adapters into Zigbee smart plugs. The Director 4K can turn the plugs on when a session starts and off when it ends. [Connect Zigbee plugs](/en/zigbee-devices).
