Video Balun & Galvanic Isolator HST-1F ECO (UTP)



Video Galvanic Isolator HSO-1F ECO (BNC)
View of the device
HST-1F-ECO is a 1-channel galvanic isolator/separator integrated with a balun (transformer), for use in a balanced UTP video line, dedicated for CCTV systems transmitting CVBS, AHD, HD-CVI or HD-TVI signals.
It galvanically isolates two parts of the transmission path, such as the part with a camera and that with a DVR or monitor, protecting the devices against the effects of potential differences (image distortions caused by stray currents). The application of the isolators is recommended in CCTV systems located in industrial environments, such as metal halls, on metal poles, and in the case of power supply from different segments of AC power network. In such circumstances some differences in potential appearing between individual grounding points introduce unfavorable operating conditions of the input/output circuitry. The differences and stray currents can generate disturbances visible in the picture and even damage the connected devices.
The bandwidth of the isolator has been adjusted accordingly to the requirements of analog HD transmission systems, allowing the transmission of video in resolutions up to 1080p. The device uses branded BNC connector, which ensures high quality and durability of the connection, even in adverse temperature conditions.
The device transmits the video signal in both directions and should be used on both sides of UTP transmission lines. In the case of using other balun on one side of a long transmission line, the recommended location of the HST-1F ECO device is by the DVR/monitor.
