He said that the system conforms to the IEEE 802.3bt standard. He also said that the unit only runs on two pairs, and he indicated that there is substantial voltage drop. I thought that the IEEE 802.3bt standard used all four pairs. 4PPoE as it is referred to. Am I mistaken? And, more importantly, why not use all four pairs? You aren't even sending data over that line.
Man, I hate to be so negative, but why not just use a WebRelay and landscape lighting power? This would allow much more wattage, still be IP controllable, would ultimately require fewer point of AC injection, and would be way less expensive.
Also, I was surprised that Brian didn't say anything about this: How can you say that the large installation referenced in the latter part of the discussion is "half a mile of lighting powered by POE" considering that you are injecting 110AC in two other places? Sounds to me like it is powered by AC and switched by PoE.

Injecting 110V? The line transformers (Cast PoE Interfaces) are PoE powered if I understand your comment.
Or is the 'half-mile' range claim you're objecting to? Cast says that distance is possible and explained how, but clearly explained distance limitations of the system.
This drawing indicates Three (3) points of AC injection. One at the PoE switch and one one the transformer of each leg. Again, this example illustrates a lighting system that is powered by AC and switched by PoE.
Yeah, that 2400 feet application was 'this is how you can do it' using the product, but Cast made the distance limitation of the PoE-only application fairly clear.
I'm no fan of munging applications into a misrepresentation, but I didn't perceive Cast was doing this. They were explaining how a system could be potentially deployed for longer ranges, but otherwise, it applies to 200 feet or less.
To your point, I'll add this as a note to our post to make it clear.
Brian, yes you are correct. The PoE is configured for up to 200' (100' per port) due to only 60 Watts of power out of each port of the the EtherWAN switch. The PoE configuration as mentioned, is targeted to the smaller sales where integrator's sell a big chunk of their business and it is a good value proposition for the customer and additional revenue for the integrator on the same sale.
When they want larger distances, you can either just use the CAST Lighting transformers up to 1200' per transformer, or if the Network Manager still wants to control it all through the switch, that is the 2nd diagram above Integrator #2 above noted. I will be posting more notes to the evaluation soon.
Great product. I deployed the previous version at 21 large electrical substations and it has performed flawlessly for years. Replacing the LEDs is pretty easy. Looking forward to seeing how this new version works.
would "Flash Glare" be defeated by a simple Pirate's Eye Patch?
Pirates frequently had to move above and below decks, from daylight to near darkness, and Sheedy says the smart ones "wore a patch over one eye to keep it dark-adapted outside." When the pirate went below decks, he could switch the patch to the outdoor eye and see in the darkness easily (potentially to fight while boarding and plundering another vessel).
No Electrician License Needed: No high-voltage license or permits are needed, and can be installed by low-voltage security or IT technicians saving thousands.
It would be important to remember that in some jurisdictions, the Province of Ontario for sure, even PoE at this level requires electrical permit and inspection, and therefore requires a licensed electrical contractor. The contention that using an electrical contractor will cost 'thousands more' should be challenged by the end user, and not relied on by integrators as a selling point. As the ESA (Ontario) continues to expand it's jurisdiction, Ontario integrators could face large penalties for ignoring this.
I heartily commend you for seeing the awesome side of it! Many IT people only see it as intrusion on their space, so good on you for seeing the benefit. I have met some great IT people who are familiar with potential safety issues with PoE installations, and there are just as many electricians who don't understand them.
What I believe Ontario's ESA's position is at the moment is, 'make sure it is done to code and that someone takes responsibility.' Thus far, it does not seem that they are actively enforcing it, but that may change as they get caught up with the hot construction market here.
I think our industry's takeaway needs to be, 'let's work together with electrical contractors to make it happen and to do it right' rather than allowing the low-bid game compromise our installations. As the technology continues to converge, so will the trades, as long as we are willing!
It's just another layer to worry about. Now I have to worry about a hacker turning off the lights or ransomware taking over the lights. Does it then become how many lights I.T. will get calls about that are off? My hope is maintenance and I.T. can work together on what will perhaps be the future.
From a physical security standpoint, the ability to tie them in with your perimeter security is actually something I am interested in.

One of my favorite IPVM Show presentations, as a video surveillance professional!
Great Topic and interesting product.

Awesome and scary at the same time as an I.T. person. Makes me wonder how much stuff will belong to I.T. in the future.
