Digital Signage Override
Digital Signage Override
Many organizations employ digital signage and cable TV systems to transmit communications in public and high-occupancy areas. Alertus’ digital signage override software transforms these devices into intelligent emergency alerting appliances, and when activated, emergency alerts scroll across digital signage and can be easily read from a distance. Most LCD screens, LED marquees, and digital display media systems are supported. Additionally, the application supports playback of alert tones and voice messages on systems with audio output capabilities. Digital signage override software also integrates seamlessly with wall-mounted Alert Beacons® to ensure unified emergency response.
Immediate: Digital signage override is rapidly deployable and can be launched via the Alertus Activation Console software from any computer or mobile device
Reliable: Not dependent on external internet connections
Zoneable: Alerts can be targeted to individual screens or groups of screens organized by category or geography
Customizable: Overrides existing display with customized, full-screen alert message that scrolls to allow for easy viewing from a distance
Personalization: Alert can be personalized to display your organization’s logo (only available if using a PC-based configuration)
Integrated: Software designed to interface with external devices, including the wall-mounted Alert Beacon®, most LCD screens, LED marquees, and digital media displays
Visual Notification: Provides notification to deaf and hard-of-hearing individuals
Cost-Effective: No recurring service fees
An emergency alert can be initiated through a variety of sources using the Alertus system, including the Alertus Console, Alertus dispatcher mobile app, panic button, and a number of inbound integrators. Notification points check in with the server periodically to determine whether an alert has been initiated and devices are active or disabled. Once an alert has been initiated and acknowledged by the system, the Alertus system can disseminate an active alert to numerous endpoints, including cable TV override.
The Alertus override client is an optional software-based client that is part of the Alertus solution. It can be configured for digital signage override or cable TV override. The Alertus override clients are Windows desktop applications that run in the system tray until an alert is sent out. When activated, they maximize and take over the screen of the computer on which they are running. They are the best option for overriding digital signage and cable TV systems when Windows-based signage endpoints or video source feeds are used. Some vendors that we have had success with using this approach include FourWinds, Scala, and Visix.
The Alertus Override clients were built on the same framework as the Alertus Desktop Notification application. All applications share similar system requirements and configuration options.
The Alertus Desktop client application requires a computer that meets the following requirements:
- Windows XP operating system or greater with the .NET 2.0 Framework (or greater) installed
- ~7 MB of free hard disk space
- Network connectivity to the Alertus Server
- Access to a user account with administrative rights that will be used to install the application
Additional Configuration Options
If the digital signage provider can retrieve content via an RSS/ATOM syndication feed, then the Alertus server can create a feed when an alert is issued, and the digital signage solution can consume this feed and alert the content.
A “proxy” solution is effective for digital signage players that are running embedded operating systems that simply display content hosted at a specified URL. Using this approach, the digital signage players can be set up to connect to the Alertus server. If there are no active alerts, the Alertus server will redirect these requests to the web page where the normal digital signage content is displayed. However, when an alert occurs, the Alertus server stops redirecting the request and instead generates a full screen page that displays the alert message. This method was designed to integrate with Cisco Digital Media players but is also compatible with other digital signage players that operate in a similar manner.
