  1. i have to do a project about WHAT ALTERNATIVE AND how to backup the captured pic from CCTV system now, i know (just a little bit) only 2 systems 1. burn into dvd 2. transfer to remote server via ftp can anyone give me more alternatives and details please -anyone know how long can 1 dvd backup the captured pic? (after compress it) because to use 120 gb hdd, you can record pic for 1 weeks. then, do i have to use 20 DVD!!!!! to backup all the data in 1 week? -how much does it cost me, if i want to backup by using remote server? (i think i have to pay $20 for 5gb storage per month. so, if i want ti backup all my 120gb data, don't i have to pay the website 480 per month!!!!! ?????) anyone have any idea, please share. i am in trouble, noe T-T
