When digital signage is specified late in a project, it usually means surface-mounted screens, visible cabling and a media player taped behind a panel. Bringing signage into the design early - at the same time as lighting and AV - gives a cleaner result. This guide covers what architects need to decide.
Display type and rating
Commercial signage displays are built for continuous operation and are rated for it - typically 16/7 or 24/7. Consumer TVs are not. Brightness matters: 350-500 nits for interiors, 700+ nits for storefronts facing daylight, 2,500+ nits for true outdoor. Specify the rating, not just the size.
Portrait, landscape and stacked
Decide orientation early - it changes the wall opening, the bracket and the power/data position. Portrait suits wayfinding and entrances; stacked pairs suit long menu boards. With SignOS the content is rotated in software (0/90/180/270), so a single mounting approach covers every orientation.
Mounting, recess and service access
A recessed display sits flush with the wall but needs a deeper back-box, ventilation and a way to service the screen without demolishing the finish. Allow a hinged or slide-out mount and a maintenance gap. Confirm the fixing substrate can carry the weight of the display plus bracket.
Power and data
Put a switched outlet and a network drop directly behind each screen position. Wired Ethernet is more reliable than Wi-Fi for signage and is worth the conduit run. If screens are on an automated lighting/BMS schedule, coordinate the power timing with the content schedule.
Video walls
For a video wall, specify narrow-bezel commercial displays and a proper video-wall mounting system with micro-adjustment. Allow structural backing, front or rear service access, and heat dissipation. The video wall guide covers how the content is split and synchronized.
Why the software choice affects the build
A platform that needs a separate media player box per screen adds a device to conceal, power and ventilate at every position. SignOS runs as an app on the display's own processor (Samsung Tizen, LG webOS, Android, Amazon Signage), so in most cases there is no player box in the wall at all - just the screen, power and data. That simplifies the detail and removes a future failure point.
