Needed a basic USB 2.0 mouse extension for 40 ft to an NVR system. This worked perfectly, and didn't even need to use the power supply. Will use again in the future! Read more
The USB camera used for quality inspection in the workshop needs to connect to a monitoring host 25 meters away. Previously, using a USB extension cable with three amplifiers still resulted in signal loss every 10 minutes. After switching to a USB Extender Over Ethernet solution, the CAT6 cable's strong interference resistance ensured stable signal transmission throughout the entire path: real-time camera footage streams smoothly without lag or distortion, and quality inspection data synchronizes instantly to the host. This replaces the frequently maintained USB extension cable setup, enabling stable operation for long-distance USB devices. Read more
As the company's IT administrator, the distance between the server room and the front desk printer exceeds 20 meters, causing severe signal attenuation with traditional USB cables. After switching to this Ethernet USB extender, I connected a 50-meter Cat6 network cable. The printer, barcode scanner, and front desk keyboard/mouse all plugged in simultaneously—plug-and-play throughout. — no drivers required, no need to power the remote devices, and transmission speeds remained stable. Testing showed copying a 1GB file via USB drive took about 30 seconds, nearly identical to connecting directly to the host's USB port. Read more
I wanted to connect my living room TV to a hard drive in my study to play 4K movies, but the 15-meter distance between rooms caused severe signal degradation with a standard USB cable. After switching to this product, the transmitter and receiver are connected via a single CAT6 cable hidden within the baseboard. The 15-meter distance is fully within the supported range, with virtually negligible signal loss: video playback is just as smooth as plugging the hard drive directly into the TV. Now, the CAT6 cable has completely replaced short USB cables, eliminating distance limitations for using USB devices across rooms and instantly upgrading the home entertainment experience. Read more
Our warehouse requires real-time transmission of data from barcode scanners and weighing scales to office computers, spanning nearly 60 meters. This extender's metal housing is exceptionally sturdy; we mounted it directly on the shelving during deployment, and it has never dropped a connection. After connecting with Cat5e Ethernet cable, barcode scanning latency is virtually imperceptible, and weighing data uploads sync instantly—far more stable than our previous WiFi module setup. For industrial environments, we recommend using Cat6 cables for superior interference resistance. Read more
