Hi Brian,
Mabuhay!
Hopefully there will be some forum members who will be able to
put forward some good recommendations.
In our dialog yesterday, I don't think the possibility of real-time video was raised.
Cameras such as these are increasingly popular -

Perhaps something like this camera, which is available "off the shelf", might
be interesting for you to consider as part of your system.
