Does output decrease with longer cable length? I'd like to use the same unit to power lights in front and back of house--probably 125-150 ft

What will increase with longer cable length is the resistance of the cable. The power lost in the cable is equal to current squared times the resistance. Therefore as the resistance goes up, the power lost to resistive heating in the cable goes up. You can mitigate this somewhat by using a larger gauge of wire for longer runs. In general, the larger the gauge of wire, the less the resistance per foot of cable. (Trust me - I'm an Electrical Engineer.) So, don't use the skinny little 16 gauge cable that sometimes comes with low-voltage AC outdoor lighting.....if you are going to have a 150' run, opt for at least 12 gauge cable or better yet 10 gauge cable. You can search on Amazon for 12/2 or 10/2 low voltage landscape wire.

Also I purchased amplifier/splitter from Home Depot, NOT the expensive Winegard amplifier. Works pretty well, but for 15 miles regular power station, you probably don't need that.

Mine was only 5 ft from my power supply. My monster power supply is plugged into the main outlet then the unit is plugged into the monster power supply.

My unit works quite well with a 20 ft. long run of Cat 6 from the router.Haven't tried anything longer than that.

The supplied cables are 60'. You could use a 150' RG5918/2 cable and a plug in power supply to avoid signal degration and power loose on the very small sized cable provided.

I run mine about 30-35 ft and the display tweaks out (flashes, runs through the different display ratios, displays the input) every time something electrical switches on (the heat, the oven, the fridge). Kind of annoying. Not sure if this is the kind of digital artifacts you are talking about, just my experience with the cable extenders. Hope this helps.

I'm using 2 ft jumpers to connect from a Patch Panel to the TrendNet switch . . . I didn't see anything in the manual about min. 5 feet cable, but I wasn't reading word-for-word -- I'm guessing that is the length needed for the Switch to detect a short cable and lower transmission to be more power "green."

Yes, I ran 13 on each side of my 45' living room walls and it worked well. But here are few comments:1. It is a good idea to install more lamps for such length, 16 or more should be better. 2. Would recommend using the 150W power supply. It may cost few more $ but will keep it on a lower load. 3. I had a bad experience with these bulbs! Few had an internal shortcut after a month of use that burned two power supply units - consider using a breaker on the 12V line. I would definitely look for higher quality bulbs than these here. Good luck!

In order to properly answer your question, you must also take into consideration the size of cable you are using. Bigger is better when it comes to the cable leading from your power pack out to your lights. If you are using 1) 300 watt circuit of this power pack, along with 12 gauge or 14 gauge cable, then you should be able to accomplish your task, but not so much if you are using 16 gauge or 18 gauge cable. Of course this could change if you are using a different power pack than is shown here.

I have seen no drop in performance but with any cable there is slight resistance over the length. With this what you would lose should be negligible.

I can't possibly tell you the real distance and I flunked physics. However, this is a transformer reducing the current to 12 volts, which ought to be good for a few feet. If you want something else, like to light up your yard, maybe a regular transformer will be in order.

I was under the impression that PoE would only work out to about 99' from the power source... is that not accurate? My understanding was if you need a run longer than 99', you needed to use an PoE injector closer to the device. Am I off base here?

I started having trouble with the cable right about 100ft. I did have a couple runs about 150ft, but I ended up having to purchase a 1000ft box of 18/2 and run it to just about all the locations over 100ft.

I ran 3 LED strips using 2 extension cables (PSU --&gt; Controller --&gt; Splitter --&gt; LED Strip --&gt; Extension cable --&gt; LED Strip --&gt; Extension Cable --&gt; LED Strip and it worked fine. Need to ensure you have the correct PSU Wattage for however long your strips are. NOTE: I have read online your maximum strip lengths should be @16.5 feet. However, using splitters allows you to maximize LED strips on one PSU. Just be mindful of the total wattage and do the math right.

I'm just toying with it. Mine leans against my garage wall with the cables running under the garage door. The cables from the panel to the controller are only about 4 feet long. There may be some energy loss with longer cables, but I haven't experimented with longer cables yet.

I don't believe you'll have a significant reduction in current unless you start talking hundreds of feet. The specs on this say it has 3 foot cables, but on mine the cables from the panel to the controller are 10 or 15 feet long. (Maybe they changed the cables, maybe they're talking about the cables that go from controller to battery, I'm not sure). The wires are made of copper, so resistance is low. You might have to splice cables together to make the distance, but as long as you do that correctly, it should work fine. Another option would be to solder your own longer cables directly to the panel, which I think would work better.

my cable is from a room in the middle of my house, up into the attic and then outside to the back so maybe 30 feet. I would expect the POE distance to be based on the repeater / power unit specs not the cameras specs.
