Help please guys(and gals)! I've had to replace my laptop on which I had my remote monitoring of my hikvision system. The computer guys have loaded the 4500 into my new laptop and have a desk top icon but when I try to click to open, the up address comes up and says cannot connect. I am using ie. I cannot get into the system. The initial cctv installer is less than helpful and won't return my calls! Help please!
