14 Analog UTP Baluns Finding a Factory Balun Design Decisions In-house manufacture of balun coils means all parts meet high standards. 100% copper is used to ensure minimal imperfections and impurities, reducing variation in signal quality. All products produced in- house are tested thoroughly. Every passive component is tested to ensure specifications are met. All active products are aged for a minimum of 3-days. Doss knows how important reliability is when it comes to security systems. We understand installations are often complex, and replacing faulty components once installed can often be a nightmare. And we frankly don’t like replacing faulty products! Not only is reliability an important factor when sourcing products, but so are the features of the products. We want to be proud of the products we sell – so we look for products that give our customers real value for money. Value to us means features and reliability that save you time and money. For this reason we search for factories with the same ethics and take true pride in their products. That’s why we source our products from only the best factories we can find. Doss only chooses factories that have a strong focus on producing a high-quality product our customers can rely on. Our range of CCTV Video Baluns have been specially sourced for their quality and reliability. The factory goes through a stringent quality control process to ensure: 1 That all of the balun balance coils are actually manufactured in-house to ensure the components meet the engineers’ specifications completely. 2 Only the best materials are used. For example, only 100% copper is used in the manufacture of the balun coils. Not only the quality of the material is important, but more windings are added to the balun coils than typical balun coils, to reduce variation in signal responses. 3 All passive components manufactured in- house are tested thoroughly to ensure they are not defective and are within the very tight specifications. 4 Every active device produced is worn-in for at least 72 hours before passing testing, resulting in a product you can be sure works out of the box. Strong durable push-pin terminals can hold up to 10kg of weight – the copper conductor is not sandwiched by flat metal terminals, rather the terminal grips onto the conductor tighter when it’s pulled! Our Doss passive balun hub (left) vs another brand (right). Components used are over-rated to ensure down-time and maintenance costs are kept low. You can also see there is simply more copper in our balance coils, and the windings are evenly distributed to ensure a nice, clean signal. There are several different forms that our baluns come in. Sealed for weather-proof installation, small and compact for direct connection to camera bodies, and several different terminations: screw, push-pin, solder, and also RJ45 socket. Big features in a small package: PTC self-resettable over-current protection, surge protection, quality balance coils and easy to install RJ45 connection. The new range of screw terminals and push-pin terminals are made from harsh-environment tolerant non-recycled plastics. An internal shot of one of our passive video baluns: it may be small but there's a lot in even our basic model. It features a 100% copper balance coil that has finer wire, but more winds for a more uniform winding (helps reduce eddy-currents and therefore improves signal quality). Our power hubs feature exactly the same components and features as the individual baluns – only possible when a factory produces all their products in-house. This ensures compatibility between all devices and that they all work together with-in specification. Our baluns (left x2) may look like other baluns (right) but there are some massive differences that you can’t see. The conductor pin in our BNC plugs and sockets are 100% copper which improves impedance matching, and reduces signal losses. Our baluns all have built-in surge protection and the balance coils are all specially engineered and tested in-house! Balun Factory & Quality Control
