I have 6 foscams throughout my house. Two dedicated to my fish tanks, the rest are more for security purposes. I have the FI9831W wireless cam's, are they perfect...no but they are 'fairly' cheap and the image quality is ok. There is no digital zoom on this model but each cam does have it's own DNS service if you don't want to configure a router for port forwarding.

I bought the LiveCams Pro app for $4.99 and can see all of the camera's in the main panel of the app on my ipad and iphone.

Each camera come's with a simple mounting unit as well so you could mount them if you wish. I have one mounted in my garage, the power cable is a standard 6 feet I think but you can get an extender cable if you need one. They do pan and tilt as well from the app which is a nice feature. For a simple relatively cheap cam, I would recommend them.

This is the one I am using:
