Sure you can. Any intercom can be connected using a IP gw connected to 
asterisk. You then install an IP camera and it's done :-) Opening the 
door is done by sending the code using asterisk sendDTMF command.

That's what we do when using existing intercom. For new installations we 
use Mobotix products (IP doorphone in SIP).
