Create a display of mobile/pc or radar and interact with it
Monitor/CCTV is done by using Render To Texture functionality, more here: https://docs.unrealengine.com/latest/INT/Engine/Content/Tools/RenderToTextureTools/index.html
Mobile display would be a combination of the previous technique with overlaying sprites, as described here: https://forums.unrealengine.com/showthread.php?10381-Blueprint-Helpful-BP-Functions&p=77800&viewfull=1#post77800
The actual implementation can vary wildly depending on your needs but this should give you good pointers.
