USB 2.0 Extender 165ft 50m with 4-Port USB HUB by Ethernet Cat5e Cat6 - USB RJ45 LAN Extension, 5V Low-Power Consumption,Two Webcams Work Sync, Support Windows,MacOS,Android,Linux, No Driver,EX60USB

J'ai installé ce extender pour faire de la surveillance avec mes webcam USB à vision nocturne, chaque caméra nécessite 19v pour être fonctionnelle. j'en ai connecté deux à ce boitier mais cela ne fonctionne pas car il n'a pas assez de puissance pour faire fonctionner les deux webcam en même temps...ce qui est dommageable car j'ai une webcam sur deux qui fonctionne.... je vais être obliger d'en commander un autre car mes webcam sont à 20 mètres du pc de contrôle.

Acquistato per spostare il pc in un'altra stanza per via della rumorosità e del calore. L'ho collegato ad un cavo cat7 da 30 metri solo perché era già presente nei corrugati tra le due stanze, altrimenti funziona benissimo con classico cat5e. La latenza è bassissima, oserei dire quasi nulla, praticamente impossibile notare la differenza.

This is a great extender; unlike 99% of similar products, there's absolutely no lag on this device whatsoever. In fact, I'm running my mouse/keyboard from it, 12+ hours a day, and I've not had a single stutter whatsoever. When you connect other heavy-duty devices (data-wise) to this hub, it copes perfectly and again there's absolutely no lag.

La compra para extender el usb de una X32 unos 30 metros y funcionó perfecto Ahora solo tengo que arreglar la latencia

I bought this product since I’m a professional photographer and was tired of Tethertools being the only realistic option for tethering, and then you’re at the mercy of USB technology and its 15 foot maximum length limitation without booster adapters. The only problem is that the unit on the camera end needs to be powered by a 5V/3A adapter, so you have to have a power source on the camera side, or do what I did and created my own tether cable out of a 25 foot Ethernet cable and a 25 foot adapter extension, wrapped in a nylon-braided sleeve. That way the remote unit on the camera is powered by the cable, and you can plug it in on your tethering station. The only limitation is the voltage drop on the adapter extension, since you can run the Ethernet cable up to 150 feet. With a 25 foot extension the voltage drop is still within acceptable ranges and it works great. You could probably find a higher voltage adapter for longer runs provided the drop is still within range (4.5-5 volts) at the end. There’s voltage calculators online that can tell you this information. I’ve been using this in my studio for about a month now and I have no issues. I have two separate camera bodies I use (Nikon D7200 and a Sony A7II) I can leave both of their USB connector cables attached to the tripod since the remote end has four USB plugs, and I can swap bodies without having to use a different tethering cable. I just plug the camera into the right cable and I’m off to the races. Overall it’s a great product, although I wish they would power the remote unit via PoE (power over Ethernet) instead of with an adapter. That would make it much more of an elegant solution, since you’d only need a single cable instead of the franken-cable I created.
