How to Choose an LED Video Wall for a Perth Project

29 May

Most LED video wall projects run into trouble because the hardware gets chosen before the right questions get asked. This guide walks through the questions that should shape your brief, before anyone starts quoting you screens.

Start with How Far Away People Will Be Standing

The sharpness of an LED display is determined by pixel pitch, which is how densely packed the LEDs are. The closer the viewing distance, the finer the pitch needs to be for the image to look sharp.

A quick rule of thumb: the minimum comfortable viewing distance in metres roughly equals the pixel pitch number. So a P2.5 screen looks sharp from about 2.5 metres. A P10 screen is designed to be viewed from 10 metres or more.

Before you look at a single product, establish the closest and furthest point people will view the screen from. Also consider what you're showing. Fine text and data need a sharper image than video or large graphics at the same distance. Get this wrong early and the hardware can't be fixed later.

Where the Screen Is Going Determines What You Need

An outdoor screen and an indoor screen are not the same product with different price tags. They are built differently, rated differently, and will perform very differently if you put the wrong one in the wrong place.

Every display has an IP rating, which is a score for how well it's sealed against dust and water. Indoor screens carry lower ratings suited to clean, dry environments. Outdoor screens in Western Australia need to be rated IP65 as a minimum, meaning fully sealed against dust and protected against water from any direction.

A screen going up on the Perth coast has different sealing requirements to one going into a Pilbara mine site. Salt air attacks exposed parts in a different way to fine mineral dust. Both need proper sealing, but the detail of what that means differs. Work out exactly where the screen is going and what the environment is like before settling on hardware.

How It Gets Mounted Matters as Much as the Screen Itself

LED displays are heavier than most people expect, and outdoor installations also have to handle wind. Neither of those are things to figure out after the screen has been ordered.

In Western Australia, structural mounting for outdoor signage has to meet AS 1170, which is the Australian engineering standard that sets the required specifications for wind pressure by region. The coastal strip and anything north of Perth sits in a higher wind zone. What works for a Perth CBD installation will not necessarily hold up on the Pilbara coast.

Any mounting attached to a building or freestanding frame above a certain height requires engineer-signed structural drawings. If your supplier can't provide that or coordinate it through a structural engineer, that's a problem worth knowing about upfront. PinnacleLED's engineering team handles structural documentation and council submissions as part of the project scope.

Sort Out Power Before Anything Gets Installed

LED displays draw more power than people usually anticipate, and the draw changes depending on what's on screen. Power supply, cabling, and circuit protection all need to be sized for the worst case, not the average.

Have a licensed electrician confirm the electrical supply against the screen's peak power figures before cable runs go in. Retrofitting electrical infrastructure after installation is significantly more expensive than getting it right first.

Any LED hardware sold in Australia must carry RCM certification, which is the mandatory Australian safety mark for electrical equipment. Ask for it before you accept delivery. A supplier who can't produce it is a risk you don't need.

Perth Heat Is Not the Same as Heat Anywhere Else

Perth summers regularly hit 40 degrees Celsius. Inside an unventilated housing or a wall-mounted installation in direct sun, it gets significantly hotter than that. A screen rated to handle 50 degrees may not cope if the enclosure it sits in traps heat well above that point.

Natural airflow is the preferred approach for cooling, particularly for sites that aren't easy to get to. Fans and active cooling systems work, but they add parts that can fail and need servicing. When PinnacleLED built the outdoor display for Iluka Resources' remote desert mine site, the enclosure was designed to manage extreme heat and sub-zero winter nights without any fans, by building the heat management into the enclosure itself rather than bolting on a cooling system.

Decide How You'll Manage the Content Before You Sign Off

How content gets onto the screen needs to be agreed before the hardware is finalised, not sorted out afterwards. Most LED systems connect to existing video or AV infrastructure, and some require dedicated content management software to schedule and update what's displayed.

If you need software to manage the content, it should be scoped and costed alongside the screen, not treated as a separate problem. Trying to integrate it after install adds time and cost. PinnacleLED's content strategy and CMS page covers the options suited to Perth installations, from simple standalone setups to network-managed systems across multiple screens.

What to Check Before You Accept Delivery

Run through the following before signing off on any hardware.

Viewing distance confirmed and matched to pixel pitch
IP rating confirmed for the specific site and installation position
Structural drawings engineer-signed and submitted where required
Wind zone compliance confirmed for the site location
Electrical supply confirmed by a licensed electrician at peak load
RCM certification provided for all hardware
Temperature range confirmed against actual enclosure conditions, not just outside air
Content software integrated and tested before installation is complete
Warranty terms and local support response times confirmed in writing

Fixing a specification problem before the hardware is ordered costs time. Fixing it after installation costs significantly more.

Request an Engineering Review

If your project is still in the planning stage, PinnacleLED's team can review your brief and provide a clear specification before any hardware decisions are made.

Contact us to request an engineering review. We'll assess your site, your viewing requirements, and any compliance obligations, and give you a straight answer, not a sales pitch.
