Since there is no real accreditation for this industry people in my field get trained by the manufactures we represent.
It is actually very intuitive. We are trained by the engineers who actually designed the products. This is productive for a few great reasons, we learn the proper way to use them and we can give feedback to the designers with our needs and concerns and usually the next generation of the products or software will have our ideas incorporated.
How does that benefit you? You end up with a really robust system that is really well thought out and tailored to your needs while still being executed properly. MOST importantly is you don’t need training or a degree to operate your own home or business electronics.
