Getting the parts.

So the cat 5 cabel wasnt that hard to get you can get it from any store that sell electronic or you can get it from ebay.I got my from a store for only 30 cent a meter.And the usb over cat 5 you can get from ebay or a electronic store but i dont know if they sell these in stores so yeah i got my from ebay for 5 $ (really cheap) you can get a much more longer one but that will cost you much more.Ok so the tools you will need are all in the picture you wont need necessary all but it good to hove sometimes much more. 

Putting it all together.

This is fairly easy beacuz you just have to conect some wires and do some solderin job for the cat 5 cable and nothing else

The recording softwear

Now that you got evrything setup and ready to go you will need a softwear to recorde what you camera see and i used Windows Movie Maker but if you wont to use somthing else there are thousand of softwear but with movie maker it easy and you can capture images from the video.So yeah now that you are ready put the camera in a nice hiden place and hit the recorde butn on movie maker 

Somthing extra

Oright so you wana get a littl bit bigger with you camera and wan make a night vision one you can get IR Led Ring from Ebay,Amazon.Or you can make one your self get a protoboard and get some 10mm IR Led and make a your self IR Led ring wich can have a wide range and self made project are better than to buy one.
