Field notes from live projects
We use this space to unpack the practical decisions behind integrated environments: why a control platform was chosen, how a network was structured, what changed on site, and where a system delivers the most day-to-day value for the client.
The articles are written for owners, consultants and project teams who want clearer thinking around automation, AV, security and infrastructure. It is less trend commentary and more applied guidance from the kind of residential and hospitality work we handle in Durban, across KwaZulu-Natal and into Mozambique.
