PoE Texas 8 Port Injector - 10/100 Passive Power Over Ethernet With 48V 60W UL Power Supply - 802.3af for VoIP Phones, WiFi Access Points, IP Cameras - Add to A Non-PoE Switch

Update 6/19/17I've used this product for a while now and it's a real workhorse. Does everything a PoE injector should do and nothing it shouldn't and at the right price to boot. Couldn't recommend it any higher.**Update**I was curious what the red barrel adapter actually does (the image indicates it's for a legacy cisco VOIP phone) so I used a multimeter to confirm that all it does is swap the polarity of the power. When in use, the LED on the unit itself turns red instead of green. This adapter has no impact on resistance or voltage - only polarity.This is a great adapter at a great price, and something people seem to often forget is that it can be difficult to mix POE/non-POE products, because sending POE to something not designed to handle POE will nearly certainly destroy it. This allows for easy mixing of POE devices with a normal switch without worrying about accidentally destroying any equipment because its sending voltage the receiving device wasn't prepared for.Having said that, it is important that you realize that this is not a switch and it requires an external switch. It will require an ethernet cord from the switch to the POE adapter, then an additional ethernet cord to your POE device - this is for each and every POE device.Finally, I would like to mention that no consumer grade IP camera feeds a stream that is anywhere near 100mbps, and if it did, you probably wouldn't be able to properly capture it anyway - so there is literally no advantage to having gigabit over 100mbit when it comes to IP cameras.

I have bought several of these POE injectors (their smaller wattage model). They have all worked well for my ever-expanding security cam system, but I had problems with the smaller size unit supplying enough juice for a large PTZ security camera, resulting in the camera crashing periodically.However, this 60W model is just what I needed and I have had no problems at all since I put it in. Nothing wrong with the smaller ones and they continue to power other fixed cameras, but they just weren't enough for my power hungry PTZ camera.The units are very well made, trouble free and seem to be high quality. A brochure ("instructions") is included which is clearly written and very helpful, but really these are simple devices and plug and play. Seller sent pleasant emails on order status and included contact information for tech support. I never had to contact tech support so I can't comment on that, but these are pretty fool-proof. Nonetheless, the customer care exhibited by the seller is exceptional, refreshing, and appreciated.Just be aware this is not a POE switch. A separate switch port will be needed for each of the devices you connect to this POE injector. Also, the instructions say it is for 10/100 Mbps only, but mine is passing through a gigabit connection without a problem.

Worked great for my POE camera system.

Works exactly as expected. Network port connects on one side, POE port to device on the other. In between is a 48V power supply that plugs into the unit. If you don't currently have a POE switch, this is a cost effective way to convert 8 ports to POE. I tested with 4x12V Amcrest bullet cameras and they worked perfectly attached to the device powered through the Ethernet cable only. It can be a bit of a pain to wire the switch to the POE injector and then the device to the POE injector, but it typically costs less than buying a multi-port POE switch. My example is my Netgear 24 port gigabit switch. It costs on sale $50-$70. Add this injector of $40 for a max of $110. Finding a 16 port switch, and typically they also only have 8 of those ports as POE, with POE costs $120+; though I did just find a 16 port POE for that price. This is cheaper overall, but that price does not include the required cabling from switch to POE injector (typically fairly cheap for the length required), but does have 8 extra gigabit ports for a total of 24; 8 POE through injector and 16 gigabit non-POE. So far, nothing to complain about.Now I don't know longevity of this device or power supply. Hopefully, that will not be a problem. So far, it works as expected after 1 week of testing and use.

These supply power to my security cameras. They were a good solution at a very reasonable price. They have been in service for years in an area of the country where we get a lot of lightening and storms passing through. They are installed in the dry but are subject to temperature extremes.They appear to be well engineered and well built. Installation was simple and they have never failed.

Have had this PoE switch for many years in my attic which becomes very hot in summer. Never got single problem with this switch. The only reason I got rid of it was because I swapped it out for a 2.5 Gb switch.

This is a cute little idea. It is a powered block of 8 POE injectors side by side. Nice idea. I used zip strips to mount the unit on my rack beside my switch and it works great. This is not the newer higher power POE + injector, it's just standard 12.95 W. If you plug something in that needs the extra power, the green light on the side blinks.Pros:1. Small and compact2. it worksCons:1. Personal preference, but It's like it's upside down. the LAN ports (non-powered) plug in on the bottom and the Powered POE ports plug in on the top. Somehow that just seems backwards to me.2. It would be nice to have a LED for each port that is using the power being provided. That way if there was a fault with a cable you would know which cable has the fault. With only the one power light on the side, it's a little vague when there is a problem.That's it. If I could take away half a star, I would probably give the 4.5 stars, but with the two con's it's just not quite perfect.
