Byte Brothers is a 24 year old company headquartered in Seattle, Washington. Our focus is on the manufacture of innovative, high quality LAN test and Real World Certification equipment for installers of twisted pair cable and IP devices (cable, VoIP phones, IP cameras). We are known for our creative approach to testing, breaking the mold to provide our customers with tools that do more and cost less. Although we are best known as the maker of the low cost Real World Certifier (tests the speed parameters of a cable plus stores 250 test reports), we have brought similar creativity to the Power Panel (for VoIP and IP camera installers), the ProTone Wire Locator with its illuminated tip and the TVR entry level LAN tester. With Byte Brothers you are always guaranteed a top product at a price that you can afford.
