|The wireless feeds are not sent to the police. The police access the wireless feeds. Seems a minor point but its a huge point in how to have the police access the x.x.1.x cameras.|
I am going to assume your x.x.1.x setup is cameras going to a networked DVR. You access the dvr remotely using its software. I am also going to assume your x.x.1.x lan is connected to the internet via a router.
In this router you configure port forwarding to the dvr's ip address. Lets say your dvr is at 192.168.1.10. Your dvr software requires a port. Lets say that port is 7000. You forward port 7000 to that dvrs ip address.
The police, using the dvr software, connect to the dvr's display by entering the routers wan port and the designated port number  to access the dvrs camera display. Form would be 22.214.171.124:7000 for example.
