I am in the same situation as the original poster. I have a dvr situated 50 metres from my office, which I need to control. The DVR software provides good control but a terrible video quality. The Web viewer provides good control, but only slightly better video quality. So I installed a KVM over IP. Now I have a standalone monitor and mouse plugged into a kvm box on my desk which extends via IP (Cat5E) to a kvm box in the security cabinet, and connects to the DVR. The picture quality is perfect but I cannot control the DVR inorder to change cameras, view recordings etc. The solution I need is long range mouse control, whether using a KVM or long range bluetooth etc. Any ideas?
