Projectors, audio systems, digital media players, and digital displays are examples of digital signage hardware. There are several sizes, resolutions, brightness levels, and interactivity capabilities available for digital signs screens. Projection displays, touchscreens, LCD/LED flat panels, and other devices are some examples. Digital media players, which house the operating system and software programs needed to operate digital signage content, can be linked to these display systems. Certain digital media players can be mounted externally on walls or stands using specialised brackets, or they can be put inside the back of a display. Some screens do not require an external media player since they are all-in-one, integrating the CPU and other infrastructure. Additional hardware, such as environmental sensors, keypad and mouse consoles for user input, printers, modems, cameras, RFID/NFC readers, WiFi routers, digital signage enclosures for outdoor installation and security, digital-to-analog converters (DACs), digital audio streaming devices, and more, can also improve the digital signage network.
