remote control

Dear All, Please can I ask, how do you view and interact with an onsite NVR screen? Put differently, can one shadow the onsite screen for support purposes so I can interact or at least see exactly what is displayed on screen from VGA/HDMI out? The particular NVR here is a Hikvision...

Hi Is it possible to control the local output of hikvision NVRs via tcp/ip commands I know you can commands to control PTZ cameras. I would like to be able to send commands that changes the display local and ideally control the HDMI and VGA outputs separately. Thanks in advance James
