How to connect my DCR-TRV285E Pal digital camera with my laptop in win 7

For pictures only you should be able to connect it with a USB cable. To retrieve video you will need to use a Firewire (IEEE1394) cable. If your laptop does not have a Firewire port you may want to purchase a Firewire card like this one from Newegg or the store of your choice:
