Equipment Protection for 12G cameras
PROTECTING YOUR INVESTMENT AND SO MUCH MORE! Ground loops, unreliable power supplies or cables and doing everything in a rush can all combine to permit stray power signals being sent down video feeds. Also where a video feed is derived from two or more pieces of equipment, differing potentials of the equipment’s grounds may increase the risk of both signal distortion, and under certain circumstances a voltage difference may also lead to an equipment damaging electric shock. LEN Galvanic Isolators have an excellent reputation for completely protecting equipment input video feeds from all these stray power voltages whilst letting through all the wanted video signals without distortion. LEN products have long been recognised as the preferred solution to protect equipment and prevent failure, especially when shooting “on location” such as a film set or live sporting event, as kit failure here has massive knock-on consequences to the shoot or live feed streams. It is therefore perhaps no surprise that LEN were approached by users of new generation 12G video cameras for a solution to a problem they were experiencing with SDI ports being blown. Camera manufacturer advice on cable connection procedures and sequences designed to overcome the issue were seen as impractical in the real world of a shoot environment and even if the advice could be followed, what if a mistake was made or the camera battery failed creating a de facto variation to the recommended connection process?

LEN galvanic isolators were seen as the solution, protecting against stray currents and passing the video signal without distortion. But could LEN create an even better solution? In response the design team at LEN have created a new product, the ‘PP Duo’ twin port protector, specifically designed for SDI Port Protection on 12G cameras and to provide two protected SDI output ports from the single camera SDI output BNC connector. Designed for 3G and higher formats only, this new isolator/splitter has been created to withstand and protect against the repetitive and damaging high transient loads that can be generated when swapping cables in the, far from ideal, circumstances of a shoot. The LEN PP Duo provides both port protection with no signal distortion and two broadcast quality signals. Like all LEN products the new PP Duo is a passive design and so is small and lightweight. It requires no power supply, improving reliability and making it suitable for a wide range of applications.
