Remote mouse for a Hikvision hybrid DVR

[tdenson 0]

I have a Hikvision hybrid DVR and wish to position it in one building but I want to operate it from another building. I can remotely access the screen (either by extending the VGA output or using Hik-Connect) but need to extend the mouse - any suggestions ? I have Cat5 between the buildings, however the distance is about 100metres and I note that any USB extender products covering more than about 100ft are very expensive.

I would see what a ethernet KVM externder would cost you could get video and the mouse in one cat five.
