Ok so this is the post-show where we're going to be asking Murray questions. Murray we've already
got a question in the chat here, does it work with 220 volts?
Well there's two components here, one takes the AC 110-220 down
to 48 volts to power the the actual ethernet cable. So it's the the power brick operates
univerally from 100 and, 100 volts into 40, 50 60 Hertz. Great
looks like we have a couple other questions.
It looks like someone was here watching you at Infocomm, and they said that you were
using the PoE to power light? We have a new product that we were showing at
Infocomm which is powering LED lighting over cat5 cable, we're going to have that
product at cedia in the next month, and we don't have that in production today
that was an early sort of this sampling the the market and getting some feedback.
They looked very very interesting, to power really LED lighting over over
cat5 cable and another low voltage, and we'll have more about that at CD. Cool,
well that sounds awesome.
We're going to get into more questions that the live stream has about it looks
like about a minute and a half of of latency, so everybody else is pretty much
waiting to actually to get to where we are. They're about a minute and a half behind
us, but there was that one question about the 220 volts, the lights.
What are the main questions that you usually get Murray, when people are
thinking about doing PoE? Is this because people don't want to hire electricians,
or is this just for ease of use? I think the biggest question we have is people look at a
camera like a Swan or Hikvision camera, and on the back of the camera it says 12 volcom of
PoE. Though the most common question is so where do I get a 12 volcom
PoE, and the manufacturers have a really poor job of explaining what that
means. 12 volcom of PoE, and we get this question everyday, you know a dozen times. 12
volcom of PoE means that it's 12 volts and powered with a local wall ward. So
you have like a transformer plugged into the wall and then It'll be 12 volts,
but when you power that 12 volcom of PoE camera over the ethernet cable, it's
actually 48 volts on the ethernet cable. The camera then internally steps the 48
volts down to the power it needs internally. Why is it 48 and a 12? Has to do
with physics of the copper in the cat5 cable. The loss in cable is a square
of the current. So if we increase the voltage from 12 volts to 48 volts, we're
cutting the current by a factor of 4, which reduces a loss by a factor of 16. So
only by going up to that 48 volts can we project let's say 20 watts or even 10
watts at 328 feet to power the device. So a 12 foot... I'm sorry, 12 volt injector would be
limited with most cameras to around 75 feet. That's why this isn't that the...
The 12-volt spec you see in the back of these cameras means this is with a wall
ward, and if it says PoE in the spec, then that means its 48 volts and it will go up to 328
feet without problem. Gotcha, alright well the last thing I want to ask you is tell us
about the future. Do you think that you know everything going to be powered over PoE in the future?
How far are we going to take this technology? Really I mean we're looking at our other
new products that we can power as I mentioned you know LED lighting is kind of a
really exciting one coming up. Essentially, we've designed a new
industry design products require less power, and we're still running you know,
12-gauge romex everywhere in a building or in a house. That 12-gauge romex can
provide 2000 watts of power which is clearly not needed.
So if we can then simply power things over over cat5 or low voltage wiring,
then we bypass the requirement for licensed electricians. We can do everything
with low voltage wiring, which means it's a much broader base of people that can
install. So the next step really is to get away from running 12 gauge romex to
a for example a lighting fixture in your ceiling that has a 6y led in it.
What's whats the point of having all that copper? So we're going to see a lot of
this move over to low voltage wiring, as reaction just to beat the labor
costs of putting in labor and copper costs
of putting in unnecessary a 2000 watt capacity we just think you don't need it.
Wow that's incredible have you- I'm guessing you haven't done this but I
mean it I would love to see like a house that was just fully you know,
PoE but I guess you know there are some things that just aren't going to be
powered over PoE, but thank you so much Murray for for for coming here and talking to us,
it was really insightful. All right well take care thanks so much
everyone go to Wi-Fi-texas.com if you are looking for PoE adapters for our
cameras the mid spans are used for you know injecting PoE over the network, so
you could just buy like an eight port mid-span and power 8 cameras right Murray?
Exactly and so either the the existing products require the 12 volt splitters we
have in stock and then your future products that are built into PoE it'll all be
powered then by our our products natively. Great, thanks so much Murray have a
nice day. Yeah, you too thanks.
