Why do I need Wi-Fi faster than my broadband speed?
Wi-Fi speed affects not just how fast data streams but also the range. A faster speed router allows for more degradation before disconnect as you move farther from the router.
Where should I place my router?
Cudy recommends placing the router at the center of your place, ensuring no more than two wooden or brick walls, or one concrete wall, between it and each room.

Great PoE++ Injector
Used this PoE++ injector to setup a new Wifi 7 Access Point that required PoE++ power. Connected it to my ethernet switch and worked perfectly!! Great Product!!
Esteban Proano –
It works as advertised
Previosuly bought a different brand POE Injector adapter which was supposed to deliver 90W and support the newer 802.3 bt, but it did not so I returned them.This PoE Injector works great out of the box, it powered my newest PTZ cameras, supports 90W and the newer 802.3bt. I can recommend this item, let’s see how long they last.

It survived a short circuit in a rain storm. Good product!
Installation was effortless. Then, about a week later it rained and the CAT5 cable end that was outdoors got soaked. There were obvious signs of a short circuit (burn marks on the connector). I was thrilled to learn that the POE Injector protected itself, and when I cleaned everything up it still worked just fine! Good product!

Works great I think they are smaller now
I bought a couple to power the Panasonic UE150 and UE160 PTZ cameras. They work great, though I think I saw smaller/lighter 90W PoE++ injectors for the same price.

Works with some devices
It was able to power some devices, but was unable to power a 802.11bt Class 4 90W device from QSC.

Connects to the camera automatically
Was a little concerned I would have trouble getting it to hook up with my camera if it wasn’t made by the same company as the camera but it was plug and play like it said it would be. It takes a short time to communicate, so be patient, it’s not a 3 second process for it to set itself up.The lights indicate what power the camera is using. Mine lit up the 30 watt light so it doesn’t need as much power as I thought it would for a PTZ camera.

Best POE injector
I use this for work. I work for a security camera manufacturer and have to do test shots out in the field. This little gem provides more than enough power for all my types of cameras.
