What are the features to choose when setting a media facade on the top of the building

Media facade on the top of the building can be very useful for billboard and advertisement . While the position is high ,it could be seen more widely.

So what features we should choose if you are gonna set one on your building.
Listen to a specialist now :

Firstly , High degree of protectioner. Lifetime of the LED important because the LED display is not cheap, as outdoor media facade,high degree of protectioner takes serious importance. For mostly LED display panels , you get only IP65 for front and IP54 on the back. That is not so sacrifice to the usage.While it means that it get no protection on the back. Anyway we still see some product which got high degree of protectioner. Like LED strip display.

Easy installation, it is true that installation take a big part of the cost, while working in a high place means you have to pay more.

Light weight. Very important in engineering science.

High light, last but not least, as advertisement , you always want to attract more eyeballs as you could.
