Byte Brothers manufactures network testing equipment and computer security products for the broadcast & pro-video industries.

Test Equipment: Byte Brothers' testing focus is on the manufacture of innovative, high quality test equipment for the computer, audio/video and security marketplaces. They are known for their creative approach to testing.... breaking the mold to provide our customers with tools that do more and cost less. Although best known as the maker of the low cost Real World Certifier (tests the speed parameters of a cable plus stores 250 test reports), Byte Brothers have brought similar creativity to the Power Panel (for VoIP and IP camera installers); the ProTone Wire Locator with its illuminated tip; the TVR entry level LAN tester; the Camera Wizard CCTV tester with Vpp display; and other powerful, affordable testers. With Byte Brothers you are always guaranteed a top product at a price that you can afford.

Equipment Security: Byte Brothers' security focus is both on the manufacture of affordable, effective computer security accessories and providing a worldwide registry for locating stolen computer equipment based on a Byte Brothers Worldwide Registry Number tag (available in Byte Brothers and Qualtec security kits). Byte Brothers offers the largest selection in the industry and sells its products under the Byte Brothers and Qualtec brands (Qualtec was acquired by Byte Brothers in March of 2002). Whether you are looking to secure expensive notebooks or desktop computers, Markertek has a choice of Byte Brothers solutions for you.
