I have a project where I need to Mirror the display of the Monitor which is connected to a DVR to a second Monitor located around 50m from the first Monitor. Can you please recommend a suitable device and provide configuration and technical details with pricing. Thanks
Thank you for your inquiry. There are a number of options available for splitting and extending a video signal. The right solution will depend on a number of factors like the type of video signal (VGA, DVI, HDMI etc.), the resolution required, (1024x768, 1080p, etc.), additional signal transportation, (USB, audio, IR, RS232 etc.) and others.

One possible solution, depending on the video signal and resolution required, might be the ST-C5V-300 - CAT5 VGA extender from NTI. This device will transport a 1600x1200 VGA signal up to 150 feet over standard CAT5e cable and has a local port. An application diagram, specifications and link to the product manual can be located here: https://www.kvm-switches-online.com/st-c5v-300.html.

For additional recommendations, please give us a call at 1-877-586-6654 or contact us via our online chat feature to discuss your project in greater detail.

Hi I want to use 2 monitors and 2 computers with Keyboard and Mouse. However, I would like to use each computer across 2 monitors using the extended desktop available on Windows 8. So each of my computer uses both monitors. Is this possible with this device?
Hello, and thank you for your inquiry. Yes, this device will allow you to share a single keyboard, mouse and dual DVI monitors with 2 computers. Please note however, it does require that the attached computers have two DVI video ports apiece. Also, the keyboard, mouse and two monitors are only available for the computer that has focus.
