Foscam FI9821W V2 Megapixel HD 1280 x 720p H.264 Wireless/Wired Pan/Tilt IP Camera with IR-Cut Filter - 26ft Night Vision and 2.8mm Lens (70° Viewing Angle)
If you are looking for something cheap to look out the window during the day or view the inside of your place the Foscam FI9821W V2 might be just the thing. I've seen them NEW as low as $47.50 on Amazon.com, used as low as $34 plus shipping and they can record to an SD card in the base.

And in the day
1080p version but it is usually going for about the same price as the 2K Amcrest IP3M-941W so you might as well get that or a Hikvision, if you do not need pan/tilt. Note both the Foscam FI9821W and the Amcrest IP3M-941W are 5 volt cams so must be withing about 10 feet of an AC outlet.
