Airlink squeezes a lot into their wireless cameras
Airlink has some interesting cameras. Their model 500W is a combination high quality 640 x 480 color daytime camera and nighttime infrared with a light sensor to know when to switch from one mode to the other.
Access to the camera can be done online for live viewing, secure access and online user configuration. It even has a motion sensor so that it starts recording when it sees movement, and the software allows for FTP upload or email notification that can be set to a schedule or when the motion sensor is activated.
