Scenarios

  1. The user wants to have full-duplex, room-to-room calling. In this case, the Control4 system must have at least two 7" In-Wall Touch Screens installed.
  1. The user wants to broadcast a message without a response. In this case, the Control4 system must have at least one 7" In-Wall Touch Screen installed.
  2. The user wants to broadcast a message with a response. In this case, the Control4 system must have at least two 7" In-Wall Touch Screens installed.
  3. The user wants to monitor the sounds in another room. In this case, the Control4 system must have at least two 7" In-Wall Touch Screens installed.
  4. The user wants to have a video conference with others. In this case, the Control4 system must have at least two devices that support Video Intercom (7” In-Wall Touch Screen with Camera, 7” Portable Touch Screen with Camera, or Door Station – Exterior).

Prerequisites

  1. Ensure that the 7" In-Wall Touch Screen (C4-TW7CO-XX) is installed as directed in the Control4 7" In-Wall Touch Screen Installation Guide available on the Dealer Portal.
  1. Ensure that your project has a Control4 controller added and identified in the Control4 system.

To add and configure a 7" In-Wall Touch Screen with Camera:

  1. To add the driver and identify the device see “How to add devices to a project.” Ensure that the In-Wall 7" Touch Screen V2 driver is added to the project tree.

    2. Note: If this touch screen will be providing audio output, the touch screen needs to be connected as an Audio end point for the room.

  1. (Optional) To configure the properties, click System Design.
  1. In the project tree, select the 7" Touch Screen object.
  1. View and change the properties in the Properties pane as needed.

    2. Modifiable properties include:

    Backlight Level—Use the up or down arrows to set the light level of the backlight. You can change the brightness of the backlight with this option by percentage, so 100% is On at full brightness and 0% is Off. Click Set to save your changes.

    Backlight Preset Level—Lets you set the default backlight level. If you ever restart or power the touch screen again, this is the backlight level it would go to. Click Set to save your changes.

    WiFi Signal Strength (%)—If Wi-Fi is used this shows the strength of the signal. Ensure that the signal is strong and robust if you use the Door Station for Wi-Fi. We recommend using Ethernet rather than Wi-Fi for best results.

    Notes: (1) Video Intercom usage. Although this device supports b/g/n, 802.11 b is not recommended for Video Intercom. (2) Wireless-n is recommended for Video Intercom. See “Wireless Network Limitations” below.

    Refresh—Click to refresh the signal strength values.

    Enable Camera— Checked by default. When checked, this allows the device to use the camera for Video Intercom in addition to audio.

    Wireless Network Limitations—Many Wi-Fi Access Points handle Multicasts (Wi-Fi simultaneously sent to multiple devices, for example, when the 7” In-Wall Touch Screen with Camera broadcasts video to all stations) by slowing down transmission speed to the 1 Mb basic rate. This can cause overall Wi-Fi congestion in the Wi-Fi network during the broadcast. Video Intercom response times and images may degrade at each device.

    If a home requires a large number of Wi-Fi Video Intercom devices, ensure that you have a robust Wi-Fi network (possibly consisting of multiple access points).
