For decades, OT (Operational Technology, the systems that run power grids, water treatment plants and industrial facilities) were isolated by design. The air gap was the security model. A system that wasn’t connected to anything couldn’t be reached by anyone. It was simple, it was effective, and for a long time it was enough. Then […]
The operator is the easiest one to forget, yet the most important factor in the equation.
We spec the infrastructure. We test the signal chain. We make sure every source reaches every screen. And then we hand it over, to a person who’s going to sit in front of that system hour after hour, making decisions that actually matter. How much time do we spend thinking about that part? There is […]
Has AV Left the Building?
For most of my career, AV meant displays, signal chains and making sure the network held up. Getting the image right, the system stable, the infrastructure solid. That’s still a big part of what we do. But somewhere along the way the line between that world and the control room got a lot less clear. […]
New Panasonic firmware – Crestron XiO Cloud support
Over the past couple of years we’ve had a beta version of Crestron Connected Display support for Panasonic CQE2 and SQE2 monitors to work with but now over the summer (in July to be precise) an official firmware with the support was released. A couple of years ago, we got support for Crestron Connected Display […]
New Crestron firmware – Multi-View
In February, at ISE, Crestron showed a new feature to the DM-NVX-38x family of devices. Multi-View. Multi-View is the ability to use a single one gigabit connection to receive up to six NVX streams. That’s actually quite impressive. I happened to have some NVX units for a project so I thought I’d test the new […]
The importance of power and control of power in an AV (or any technical) installation
Well, of course power is importand in any technical installation. That goes without saying. Put there is power and there is power. What and Why? A device can be powered using a normal power outlet in the wall and use what is provided there. Here in Sweden, that would be 230V. We can also use […]
Another really excellent change in Dante Controller!
A while back Audinate made a new feature that was long overdue. Themes. We used to have the light theme as the only theme and now we got a dark theme. Maybe a small change but so great! Today they released another excellent one. For some reason Audinate at some point in time decided to […]
Thoughts on security in ProAV and in general
Security in anything network connected has always been important. It doesn’t matter if it’s a big corporation or a simple baby monitor at home.This is a text about common sense but also my personal opinions. It’s not a comprehensive guide or an answer to everything yu ever wanted to know on any topic whatsoever. But […]
802-WHAT…?
When in AV (Audio Visual) we are often met by three-letter acronyms. And sometimes it’s just numbers. In this article it’s the numbers 8, 0 and 2. We are met by them together with other numbers and letters almost daily, some examples are 802.11, 802.3, 802.1. Then let’s add some letters to… 802.1q, 802.3bt, 802.11n or even more numbers. 802.15.4. But what do they all have in common? And what sets them apart?
Netgear and their AV switches that changed our installations
Traditionally, AV installations used networks out of necessity and often just as a way to connect devices together to be able to communicate between them for sending simple control commands. Often, these installations didn’t have any outside connection to a corporate LAN or the internet. But AV evolved and new products evolved with it. AV […]
