Some of the things to look for when purchasing a security camera:
1. The number of lines of resolution. Try to get one with at least 520 lines. The higher the number, the better. The 4 pack for $80 only has 420 lines so I would stay away from those; however, the single one for $79 has 650 lines.
The number of lines is important if you want to see detail like people's faces. If you only care if you notice a person in your back yard, then any of these would work for you.
2. The mm rating. The larger the number, the more zoom it has. If you want to capture a wider angle, get a 4mm lens but if you want to capture something farther away and zoomed up, get a 9mm lens. You can compromise by getting something in between.
3. The number of LEDs is really a useless rating. You can have one single LED that is brighter than 45 LEDs because there are different technologies involved in some of the newer LEDs. Notice, however, that the LEDs in these cameras are quasi infrared and some of the newer bright cree leds are usually in the visible spectrum. I call these quasi infrared because you can still see them glowing a faint red and are not completely invisible to the naked eye. If you are to compare two models of the same brand using the same LED types, then the number of LEDs can give you a sense of brightness difference. Do not believe anything that says they go hundreds of feet in complete darkness because the LEDs scatter light too much to concentrate it all into that kind of distance.
I have a bunch of cameras around and have tried so many brands and discovered you really do get what you pay for. Those cheap ones are generally crap while the more expensive ones really do have a better picture.
4. Notice that some models include audio so keep that in mind when selecting which one to buy.
5. I got some crappy cameras with one of my Zmodo DVRs that I bought from woot and I'm looking at those SONY EFFIO-E ones as a possible replacement for them. I'm just going to check around to make sure the pricing is right and then I'll probably buy the maximum of 3 that woot will allow me to buy. Too bad they impose a limit of 3 on something like a camera for people that have a 16 channel DVR.

Although a Wifi model is easier to hook up, they are not completely wireless. You still need to provide power to them. So if you plan on having them outdoors or on your roof, how do you get power to them? Why not also just run a video cable too? As for me, I use a balun and then run Cat 5e cable for audio, video, and power, all in one cable.
Besides, Wifi models usually do not connect to a DVR and are normally self-contained. That being said, how would you record your video with a Wifi model unless you plan on having a computer installed for that purpose. Those stand-alone security DVRs usually do not have support for Wifi cameras. Additionally, if you have multiple Wifi cameras, setting them all up so you can watch them from outside your firewall can be a challenge considering every camera will need to be on a separate open port.
