interfacing a webcam to an external ram

[force]

hey peepz,
I am doing a security systems project, where there is a motion sensor , a siren and a webcam.When the motion is sensed the siren goes on and the webcam captures the image and stores it on the computer. All these are done now i need an external RAM to store atleast one frame from the webcam. The external RAM is to be interfaced to a laptop.
Could any people tell me on how to interface a webcam to an external RAM. The RAM is used to store one frame from the webcam when the motion is sensed by the motion detector.

1 mp digital cameras are a dime a dozen these days and take a better still then
many web cams I've seen.  They come ready to go with ram.  I would open one
up and run external wires to the shutter switch and the battery connectors.  Many will plug right into a usb on a laptop.
