accessing NVR through local network

[smartgenesis 0]

Hello everyone.,

 

This is the the first time i m posting a query in this forum, i have a IP CCTV network installed in my office,

i need to access the NVR from my office network PC's for local viewing. both the networks have routers and different network settings(IP, gateway, subnet).,

Sorry, But i m a rookie in computer networking. So, it will be a great help if some can guide me through this in laymans language.

 

I am posting an image below depicting how exactly existing networks are present & some details that i could notice. Hope to find a solution here ASAP. Thank You
