Best consumer IP camera for the buck

I've been in the market for a good IP camera for a while now and as it was not very easy to find something good enough for my requirements, I will share my findings with you.
My requirements are the following, and the camera that best matched them in a budget of not more than 150 EUR / 200$ is Foscam FI8918W:

nr	requirement	description	compliance	Comments
1	must have	to be usable in Surveillance Station (Synology DiskStation) so you can record / motion record	partial	no audio
2	must have	to be usable in low light or even better, in no light - with most cameras you can see almost nothing at dawn	YES	night vision
3	must have	have as much of an wideangle as possible (for indoor use I see a 75-80 degrees angle view optimal so you have almost 100% coverage of the entire room if placed in a corner).	partial	67⁰
4	must have	resolution of 640 x 480 or better	YES	15 fps at 640 x 480
5	must have	stealth - be quiet when panning / tilting and being able to turn off front leds	YES
6	nice to have	have WiFi so no data cables are required (just plug it in the air-conditioner wall outlet)	YES	b/g
7	nice to have	use compression so storage and bandwidth requirements are not high and	NO	MJPEG only
8	nice to have	pan & tilt	YES
9	nice to have	easy to use web gui - not important if connected to a surveillance station (Synology DiskStation)	partial	many clicks to authenticate, no remember password option
10	nice to have	have not expensive apps for smartphones	YES	for iOS and Android
11	nice to have	to be able to disable WiFi when connected by wire	YES
12	nice to have	be able to upload motion detected video with sound by FTP so you have a backup if the recording server is not working / not available	NO
