Description
The Dahua PFM791 is a high-performance HD video isolator that eliminates HDCVI image interference caused by ground loops. This advanced device provides the highest quality video transmission in both residential and commercial settings. Its compact size and compatibility with junction boxes make it easy to install indoors or anywhere with limited space.
One of the standout features of the Dahua PFM791 is its impressive insertion loss of only 0.5dB. This ensures that the video signal remains strong and stable, even when passing through the isolator. This enables the transmission of clear and crisp images without any discernible decrease in quality. In addition, the isolator has a wide frequency response of 0-65MHz, ensuring that it can efficiently handle various HDCVI signals.
You can use the Dahua PFM791 with any system that has 75 input and 75 output impedance. This means you can easily add it to your existing setup without having any problems. The isolator also has an impressive isolation voltage of 800V(min.) and an isolation resistance of 100MΩ. This provides a high level of protection against potential electrical interference, ensuring that the video signal remains clean and unaffected.
ESD protection makes the Dahua PFM791 safe to use in areas with a lot of static electricity. It has a contact discharge of 600V and an air discharge of 8000V, providing reliable protection against potential discharges that could damage the device. This advanced protection ensures that the isolator remains in top working condition, delivering high-quality images consistently.
With its impressive technical specifications, advanced protection features, and compact design, it is the ideal solution for maintaining the highest level of video quality in any HDCVI system. So, if you want to ensure a clear and uninterrupted video transmission, the Dahua PFM791 is a must-have device for your setup.
