BV-Tech Gigabit Power Over Ethernet PoE+ Injector | 30W | Plug & Play | up to 325 Feet

After having the first one fail the replacement is working well.

I have used these a few times and they seem to be reliable.

Works as advertised.

Works as expected, Standards based. Good value!PoE started years ago as a hack with people putting 12 to 68 DC volts on the unused wires in the Ethernet cable as needed for custom ad-hoc applications. I wired up several such custom injectors 15 years ago for roof-mounted can-tennas and other projects. The classic injectors were super simple, and could be made from a pair of RJ45 jacks and a few inches of spare Cat5 cable. But it was not a consumer ready technology! - We always had to be carefull with the powered end, to not accidently plug it into an unsuspecting NIC and fry it, also we couldn't get Gigabit speeds as Gigabit requires all four pairs.Fast forward 15 years, and I'm wiring my house with surveillance cameras. I am so thrilled that now we have a Gigabit compatible PoE standard! The standard is safe for unsuspecting devices such that if I were to accidentally plug a powered end into my laptop, it will not fry the NIC with 48 volts! Additionally all four pairs can be used for data and power making the power transmission more efficient, and the data 10x faster. Running a single inexpensive cable to get reliable power and hard-wired data reliability is so much easier and the result so much more reliable than the alternatives (flakey jammable wireless signals, battery powered devices or running TWO wires - uggg! no thanks!).This device has worked great for my camera ( GW Security VDG2040IP HD Network ONVIF PoE 5MP 1080P Security Bullet IP Camera (White) ) Also, it is "compatible" with (but not compliant?) with the 802.3at ("active" or smart) PoE standard.Since i can't see much of an overall price difference between "passive" 803.2af devices and "smart" (803.2at Type 1 or 2) products, I would definitely recommend the smarter "at" devices (like this product) over the older passive "af" standard. Of course the newer "at" devices are compatible with "af" devices, but a mixed pair is limited to the lower power and slower data speeds of the older standard.However, If you need more than 13 watts for the Powered Device (PD) get a "PoE+" device (802.3at-2009 aka Type 2), which I don't believe this device is. This product's description and title do not call out "PoE+" specifically, although 802.3af/at "compatibility" is claimed. This leads me to believe that this is likely an "802.3at Type 1" device which claims to have some extra power to spare beyond the 15W minimum.It works great for my Camera, but if you have a larger PTZ with defrost/ice-melt or some other device that needs a full 25-30 Watts at the device, get one that specifically claims "PoE+" or "Type 2" or "802.3at-2009" like TRENDnet Gigabit Power over Ethernet Plus (PoE+) Injector, TPE-115GI.I'don't know why many of these product listing are (purposefully?) so vague. If I were buying again I would stick to listings that clearly identify their claimed standards compliance rather than just claiming to be "compatible" with the standard, and claiming the wattage of the higher standard which it may or may not actually implement. I would get a product that specifically claims _compliance_ (rather than "compatibility"!) with "802.3at" Type 1 (13 watts) or "802.3at" Type 2 (25 watts).There are other devices ( TRENDnet Gigabit Power over Ethernet (PoE) Injector, TPE-113GI ) that more clearly state their capabilities. Being more confident in what you are getting is better than trying to save $10 on a Type 2 (30W) but actually spending $4 extra on a Type 1 (15 W). It doesn't actually claim to be PoE+ but lists the same 30W capacity leaving you to assume it has the same capabilites of the other devices that list 30W when that may not be the case. This product may be somewhere in-between - I don't have test equipment, but next time I shop, I'll reward the more precise and specific product listings over the ambiguous ones.The attached photo is cropped from footage from the surveillance camera powered by this device.

Works as expected

I'm sorry to report that this POE did not preform well. I perched it to power a Riolink POE camera. Initially it seemed to work ok, however after a month I began having intermediate video drop outs. When I pinged the camera from the router, I would get not found, or dropped packet errors. After checking all the cables I finally concluded that the power being supplied by this POE must be faulty. I ordered a Reolink POE, connected it, and the camera has preformed flawlessly. I don't recommend this product.

I don't know a ton about POE and just saw different W ratings . . . 30W, 60W . . . I figured maybe the voltage was different on higher watt units but it didn't really way. This one worked with the puck style unifi Access Point, the Wifi 6 version whereas the unifi branded one didn't work. They were both 30W and I didn't look beyond that to understand the difference. I just returned the unifi one! And generally I won't buy unifi anything anymore but that's a different review!

Works just as I had hoped with a new UniFi 7 series access point.
