NAT with different subnets

We have a hub and spoke architecture:

HQ - PIX515, Cisco 3662 Router
Location1 - Cisco 1600 Router
Location2 - Cisco 1600 Router
Location3 - Cisco 1600 Router
Location4 - Cisco 1600 Router

Each location is connect to HQ via a Point-to-Point Full T1.

Each location is on a diffent subnet (e.g. 10.100.X.X - HQ, 10.1.X.X - Loc1, 10.2.X.X - Loc2, etc.)

We have a Security Camera Workstation at each location, that we would like to be able to access from the outside via http.

I have setup a public IP for the HQ site, and can access HQ's security cameras from the outside.

I would like to be able to access the other workstations from the outside via public IP's, as well. How can I accomplish that? How would I NAT across different subnets?

As long as the PIX can ping the remote camera ws, you can nat it the same way you would a local one:
All networks that the pix knows about and routes inside are "inside" and available to nat to an outside IP address
static (inside,outside) 12.34.56.7 10.100.2.2 netmask 255.255.255.255
static (inside,outside) 12.34.56.8 10.1.1.12 netmask 255.255.255.255
static (inside,outside) 12.34.56.9 10.2.2.11 netmask 255.255.255.255
static (inside,outside) 12.34.56.10 10.3.3.33 netmask 255.255.255.255
