Sorry for the long post, but I thought some more information is important here.

POE. look for a camera with PowerOverEthernet (POE). the Foscam fi9828w does not have it. POE is nice because you only have to run 1 wire to that part of your building instead of 2 (ethernet & power). Routers/ubs with POE ports are cheap these days

PTZ is a cool function to play with when you are sitting behind the controls. Like a full time security guard or so. But in a home situation, in my humble opinion, it is not a necessary feature. The camera will be operating on its own 99% of the time anyways. And PTZ adds unnecessary costs to the end-price and decreases the longevity of the camera (mechanical moving parts). Given a budget level, I would forego PTZ and increase the quality of the camera and/or IR lights

Low Light. Most economic priced IP camera´s can show nice pictures/movies during daylight. It is at night where the issues begin. So to me, a very important feature (and end-price cost element..) is the performance of the camera during low light conditions. I do not know this Foscam model, but in the past I have been less than impressed with their low light performance.
- Low light performance is so important because in the end, we want to see a clear face at night (the burglar, the thief, the new boyfriend of your daughter,...). See for example poor Tane´s example from a while ago (his bike got stolen at night...)

- Without PTZ, you need to decide on the camera lens and where to focus it on. Security guys call this ´choke points´ inside the field of vision. This is the area where facial recognition should be possible. It can be 1 meter from the camera or 10 meters away. But the further away, the higher resolution and stronger IR lights you need..

Movement sensor. is very important, your NAS can´t record all hours of every day. But outside movement detection is rife with issues. The most stupid things will trigger it, movement of the sun, changing shade conditions, falling leaves, temperature changes,... Typically, the movement sensing in IPcamera´s is pretty basic (for lack of space and/or budget reasons). I suggest that you consider running separate software (on the Homeseer computer, which I do) which can add more sophistication to it. I use, for example, BlueIris.
Perhaps some other brands to look into are Hikvision (becoming very populair with the hobby crowd in the USA this past year), Dahua and Acti.
A nice blog resource to dig into is
http://www.networkcameracritic.com who does very, very extensive reviews on many IP camera´s. Here are some examples of this reviews on dome´s
