im looking to setup some kind of surveillance system around my house. i was thinking of setting up two cameras, one infront of my house faceing directly foward and one on the corner of my house facing oncomming traffic (i live on a one way). ideally i would like to wire these cameras to my computer and have it record to a hard drive, maybe record 3/4 days, maybe a week. and then start overwriting the first day, etc. what are some decent cameras out there that would allow me to capture this? something with good quality and isnt too choppy. also what kind of card would i need to put in my computer to wire these up? im new to this kind of stuff so what im posting is off of the little information that ive gathered, if theres anything wrong or a better route, please fill me in. any help is appreciated. thanks!
