X10 will have the camers you are looking for.
With the monitoring features you are looking for.
I would recommend going with wired runs for stability anyhow.
and camera via motion sensor.
To lock and unlock door, you will need a doorstrike or something like this
http://www.sensorsandmore.com/?mod=product&cat_id=14&product_id=28 with a rigged remote connected to a contact closure device like X10's
universal module.
DVR will need to be purchased elsewhere unless you want to use your computer, then there's a usb interface
that X10 has that can do that.
or check out
http://www.qps-inc.com for fingerprint locks and camera + DVR systems. no computer interface for
scripting/macro/or other logic to trigger opening or unlocking of stuff.
I don't know of a complete system package anywhere that does exactly what you want... Just bits and pieces from
different sources (including X10) and a little manual intervention to make it all happen.
