Video Intercom Intergration?

[MFLII]

I'm looking to add cameras to my home - for regular exterior monitoring, the Foscam units will work great - however i'd like to also have video monitoring ability for my front door - due to the architecture there is really not a place to mount a traditional camera (or dome camera) in a place that will get the shot of whomever is at the front door - therefore i was looking at some flush mounted options such as video intercoms - are there any products that would work with the Eyez-On EnvisaLink system as i'd like to be able to remotely monitor this camera using my smartphone just as i could a Foscam camera - thanks for any advice
