    Got a single ethernet cable and want to install multiple PoE Cameras? This lil device will do the trick:

    Price Paid: $30 w/Prime Shipping

    Think of this as a Wall-Mountable PoE powered 5 Port PoE switch :)

    This takes a PoE+ (802.3AT 25.5W) and splits it into four PoE (802.3AF 14.5W) ports giving you ~6W evenly per port which is plenty enough to run most fixed IP Cameras.

    If your looking for a PoE+ injector this should do the trick: Amazon.com: BV-Tech POE-I100G Gigabit Single Port 30W PoE Injector (Black): Computers & Accessories

    Most NVR's w/built in PoE already output PoE+ for use w/PTZ, however few of the cheap affordable PoE switches do.

    I installed this in my Garage to split the existing cable monitoring the inside of my cat-door so I could hookup the varifocal turret.. I also intend on moving an older camera into the garage for watching the bay and another starlight watching other side of driveway.. So eventually I intend to use all 4 ports, and I also wanted several PoE ports near the Varifocal Turret for future reviews, as thats the camera to beat.. I already have 4 ethernet cables in the garage and really didnt want to run 4 more.

    I have 4 cameras hooked up for testing right now, in daytime its pulling 12W-14W total from my midspan.. half of the cameras im testing dont have IR and at night I'm seeing 14-17W combined.. might be as high as 21W if they all had IR.. as always YMMV.

    Daytime:

    Night Time (w/2 IR Cameras and 2 non-IR Cameras):

    Typically I'd suggest running more ethernet cable, its more cost effective and dont have this single point of failure.. but if your in a pinch, this should do the job just fine.. just dont expect to run any PTZ's off it.

    Seriously overdriving this thing with the Ultra Starlight (heated) and an IR Cannon on a separate 12v splitter.. here's the poo man's PoE+ 12v splitter ;)

    specs said it only had 24w of output power; but I think its more along the lines of it'll handle whatever you can give it and 25w is only whats guaranteed via spec.. giving me ~9W per port if spread evenly.

    no packetloss or any issues so far.

    This is exactly what I need for a current project. Do you have a link to where you got yours on Ali? Amazon is sold out.

    Thanks @nayr

    @bug99 thats how its currently setup as a temp. Its ugly and too many points of failure for my liking so this thing will fit the bill perfectly. Going in a garage so moisture wont be an issue. Good lookin out fellas

    I ordered another one of these DHL Shipped in less than a week for $48USD from: New Mini 10/100M 4 Ports POE Extender 25.5W Extend 120 Meters IEEE802.3af POE Network Devices Plug and Play-in CCTV Accessories from Security & Protection on Aliexpress.com | Alibaba Group

    the original one is running in a NMEA box on the side of my house acting as a fancy power splitter for my Ultra and External IR, seems to be doing fine.. might be adding a LPR camera to the box so having another port there and ready will be nice.

    Which poe injector would be recommend to use with this? Can the TP-Link 8-Port Gigabit Ethernet PoE Desktop Switch with 4-PoE Ports be used, or would it have to be a single poe injector. Thanks

    You'd want an 802.3AT capable injector/switch/midspan.. aka PoE+

    I rarely make recommendations for equipment I dont have any experience with.. leme know when your looking for 24-48 port options.

    lots of discussions on here about affordable PoE switches; search.

    i already have a poe switch but not a poe+, so maybe it might be best if i buy a single one.

    Thanks, I will go with this, much cheaper than buying new switch.
