i have not tried the outdoor cameras yet, but you do need to buy the camera kit with a reciever

This kit has the minicam and 4 camera reciever, the minicam for indoors is great. It monitors my dads storefront with a 100+ degree wide angle and can see faces clearly at 20 ft. I remind you this is an indoor camera and a mini one, so it was made for concealment and close range, the outdoor camera will have more range and clairity. With a 300GB harddrive I can record a loop of about 30 days @ 25fps (smooth video) with one camera so about 7 days with 4 cameras attached, it will automatically loop itself to record over the first day. The software is easy to use, and you can also monitor things from any remote computer connected to the internet (like at work), iits password protected and you can set the cameras to record at certain times of the day, all the time, motion, voice activated (if you buy a camerawith motion and sound) etc..... Video File format is MPEG 4 and will be continuiously saved in a folder of your choice with date and time for the recordings, usually theyre in 15 minute span recording per file (you can adjust this). Its good to have internet access to your cameras when youre away, it makes you feel a lot more secure knowing whats going on.
Total cost was about $150 for a wired camera and pc card. not too bad for security.
If youre wondering on how clear the wireless looks, we had a camera running on a 9v battery next door to us @ 50ft away and it looked even better than our micro cam. This was through a wall also. The wireless cams come with 2 power sources, a battery connector for 9v or a wall adaptor (included). pretty convienient when you dont need 100 ft of cable to run to the camera itself.
