Indoor vs outdoor

Indoor vs outdoor digital signage: brightness, IP rating and cooling

The same size can need a different panel outdoors. Decide brightness, ingress protection and thermal design from the site, not the room label.

Last updated · 2026-10-23

Quick answer

  • Indoor commercial panels are typically 250–700 cd/m²; outdoor high-bright models are 1,500–3,500 cd/m².
  • Outdoor families list IP55/IP65 protection and fan or air-conditioner cooling options.
  • A window-facing screen is its own condition; it may need high brightness even though it is indoors.
  • Mounting, power, drainage and service access differ between indoor and outdoor sites.

IP rating and cooling are a system

An IP rating describes dust and water protection, not heat. An outdoor enclosure also needs a thermal path: fan cooling, air conditioning or designed airflow. Ask for the exact IP rating, cooling method and operating temperature on the quotation.

“Outdoor” is not a specification by itself. Confirm the rating and cooling for the exact model and site.

What to send for a quote

  • Photo of the wall, ceiling or ground position.
  • Sun direction and hours of direct light.
  • Rain, dust and wind exposure; whether under a canopy.
  • Viewing distance, size, quantity and destination country.

Frequently asked questions

Questions buyers ask about this decision

Can an indoor screen go in a covered outdoor area?

Only after checking humidity, dust, temperature and condensation. If rain or dust can reach the screen, use an outdoor model.

What IP rating is needed for rain?

Selected outdoor models list IP55 and IP65. Confirm the exact rating, test condition and installation orientation on the datasheet.

Do outdoor screens need air conditioning?

Not always. Fan cooling can suit shaded or moderate sites; direct sun and high temperature may need air conditioning. The decision depends on heat load and site temperature.

What brightness for a shop window?

Measure the window at midday. A shaded wall may be fine at 500–700 cd/m²; a sunlit window may need 1,500–3,500 cd/m². If direct sun is long, use the outdoor family.
