I have a CCTV system that was setup and configured for me by an IT consultant that I hired that I'm no longer able to get in touch with.  I relied on him for logging in to the system for any thing I needed done.  I've just recently moved offices and now I'm not able to get into my CCTV system anymore.  Is there a way to factory reset this particular system?  See details below. 
  
And thank you in advance for any help you can provide!
