If I need a second monitor working on a computer 750 feet away, what type of wire/cable should I use?

Query by Chris K: If I need to have a second keep track of operating on a laptop or computer 750 feet absent, what sort of wire/cable need to I use?
I experimented with to uncover a video card with a BNC Output, but apparently there is no these kinds of factor.....they only look to occur as "Input" on capture cards. This is a perform-connected query, and its bugging me. Im setting up a security camera method, and the company wants a keep track of at the DVR (Straight up regular pc with a seize card and large hard disk), as nicely as the again of their Huge warehouse. The DVR has an open PCI Express slot, aswell as PCI. Any guidance???

750 ft is a prolonged way, it is not likely that any regular type of cable will get a high frequency analogue signal that significantly devoid of as well much deterioration in high quality, and surely your video clip card would not be ready to drive the signal.

You will need a thing fairly various and certain for the objective, unless of course you can place a 2nd personal computer at the remote location and use some sort of remote desktop, but ethernet above copper is generally constrained to half that distance even at 10MBPs, so you would need optic fibre.

Transmitting the signal above UHF is probable illegal at the ability you would need to have, so I guess that is out as well.

I would say a couple of ethernet cards able of fibre and one more machine at the far stop of the warehouse, and do it around remote desktop.
