Digital signage can be collaborative, or under the control of a single admin, depending upon the system. Some ranges are updated by writing media to SD cards, more advanced systems offer remote publishing, either directly or via FTP, and this can be much easier to co-ordinate multiple updates.
Hardware such as the Panasonic Space Player is designed for ease of installation in retail environments and it can be fitted quickly to pre-existing lighting tracks. Once mains power is available, all further updating can be via wifi or a handheld remote. Units such as there offer lamp-free projection which reduces the overall cost of operation when considered across the lifetime of the project.
We generally have a range units available that we can use to demonstrate concepts in digital signage. The aim is always to create a reliable and easy to use system. It often makes sense to re-use existing data if this can be done, for example if a corporate website is regularly updated, this data cab often be re-purposed for digital signage, which is fantastic time saver. Feel free to ask us any digital signage questions you may have.
