By "video output" of 160 meters / 525 feet are you referring to the HDMI or VGA video cable from the NVR being that length or the CAT-5e/6 cable from the NVR to a camera being that length?

You'd be hard pressed to find a solution for HDMI that distance and it would be costly. Wireless maybe but.....not the best idea, IMO and not cheap, either.
Consider using VGA video over CAT-6 for 1/4 the cost, 1024 x 768 up to 495 ft., 800 x 600 to 660 ft. from Cable Matters here.
This SIIG unit claims 1920 x 1200 up to 1,000 feet here on amazon, a good place to purchase in case it doesn't live up to its claims.
Or deploy your Google Fu to locate similar VGA over CAT-6 devices where you might find a higher resolution for your 525 feet, likely for some extra $$$.
