What Is Digital Signage? The Complete Guide

Quick answer: Digital signage is the use of TV screens to show images, videos, menus and messages that you control from software. You upload content to a cloud dashboard, a small app on the screen plays it, and you can change it anytime from your phone.

How Digital Signage Works

Every setup has three parts: a screen, a media player, and software. The screen can be any TV. The player is either built into a smart TV or a small device such as an Amazon Fire TV Stick, Amazon Signage Stick, Android TV box, Raspberry Pi or Windows PC. The software, often called a CMS, is where you upload content, build playlists and schedule what plays when.

Because the software is in the cloud, you can update one screen or hundreds from anywhere.

Common Uses

Restaurants and cafes use digital menu boards. Retail shops show promotions in windows and at the till. Gyms show class timetables. Offices and schools share announcements. Hotels show welcome messages and event schedules. Churches show service times and lyrics.

Types Of Digital Signage

Indoor screens are the most common. Window displays face the street and need brighter screens. Video walls join several screens into one large picture. Interactive kiosks add touch. Digital out of home (DOOH) refers to advertising screens in public places.

What You Can Show

Images, videos, menus, slideshows, web pages, social media feeds, live clocks, weather and other widgets. Scheduling (also called dayparting) lets you show breakfast menus in the morning and dinner menus at night automatically.

How Much It Costs

Software ranges from free to around $50 per screen per month depending on the provider and features. Hardware can be as simple as a TV you already own plus a low cost streaming stick. PosterBooking has a free plan, with paid plans for larger networks. See our full digital signage cost guide for details.
