Power Injection No Longer Needed?

[jasondavid]

I was planning on purchasing the wire tracks from Holiday Coro for my permanent light install and asked about the size of the tracks and if they were large enough to conceal power injection t-connector/wires. In response to this, they sent the following:

 Please note that as of January 2019, HolidayCoro has changed our policy regarding power injection. While power injection was common from around 2010 to 2018, with the advent of Long Range receivers, the need for power injection in nearly every project is no longer needed. As such, we no longer provide any advice or design of systems involving power injection.

I'm struggling to understand why "the need for power injection in nearly every project is no longer needed". The only alternative I can think of is that I would be splitting up the runs along the roof line into groups of 100 instead of stringing them all together. Alternatively, perhaps they are suggesting that I run a line of ethernet to differential receivers around the perimeter of the house and run each ~100 pixel section of lights this way. I'd still need to buy additional power supplies and waterproof enclosures, not to mention needing to run a long piece of wire up from each of these differential receivers to each of the distinct lines of pixels instead of just chaining the data off of a continuous line and power inject like I did with my permanent install several years ago. 

So, what am I missing? Is there another alternative to power injection that I'm not thinking about here? Their response has become a riddle to me and it bothers me that I can't solve it. :-)

False.
Sounds like they do not want to take calls on the subject. Might want to look at other venders.....

Translation.... Covid hit in 2019, massive shortage on controllers and wire, everyone was McGuyvering every scrap they could find to make their display work, and nothing else better to do in the lockdown.  Their support was probably overwhelmed, stopped supporting it, found out they did not need to, and never offered it again.

Long runs on a roof line are the only place I still use power injection.  Some effects just don't play right if you divide the lines up in sections for some reason.  I would prefer not to power inject anything, but some sequence effects look fine on divided lines, others look terrible.  Addtionally, xLights still has a lot of math issues with some of their effects as well.  If you go left to right on one window, and right to left on the other, they will play differently on several effects.  I have learned to set up everything in xlights going left to right in one direction, and if I HAVE to feed the cable from the right side, I will still configure xLights left to right, and reverse it on the controller.

Sounds like HC is advocating no long strings (without really saying it).  They want to see you long range receivers to break up strings.  Sometimes that works well, but sometimes long strings are really the only practical way to do it...

Bad advise - but it's HC, so why am I not surprised....

My general concept about HC is that they do CoroPlast just fine, but I won't touch anything else from them.
