[X4U] Recomm for wireless security cam

[Crandon David]

Hello Everyone:

I'd like to put a wireless security cam in my backyard and be able to  
view it on my DP500 Mac. I'm new to this area, so I'd like some  
hardware recommendations.

It appears there are two ways to transmit wireless. One uses the  
"network" "wifi" "8011" "G" way. This would require me to buy only  
the cam and a wireless router, correct?

The other cams use the 2.4GHz system similar to everyone's cordless  
telephones. These seem to all have traditional composite RCA type  
video outputs. This would mean I'd have to buy a PCI card to allow  
video inputs. While they do sell convertors for video-to-USB 2.0, I  
don't have USB 2.0 (just 1.0). I've been told that USB 1.0 is not  
fast enough for the video, so I'd have to buy a USB2.0 PCI card if I  
chose to input via USB. Is this all correct?

Other potential considerations: I don't want to spend an arm and a  
leg on the camera (seems some network cams can be many hundreds of  
dollars). I don't want the camera to be huge and bulky.

What's everyone think?

Thanks,

David
