IP Video Camera Server Software

Hello I am looking for a very expensive way to record my ip cameras online. I have right now 4 ip cam's and am looking for a way that I can record the activity on these cam's and have it record to an online service. Or software program that I can put on a server that can got to these ip cameras and automatically record the content and save it.

So looking for ether server software I can use for surveillance software I can stick on a server I own that would do the work.
Then I can just login to my server download the records and view later.

I see ton's of products that allow you to view multiple cams in your house and record them to your hard drive but I am looking for something so I don't have to leave a computer on to record. Yet I don't want to pay huge prices.

I would like to maybe find software I can use and stick on a server that could do the same thing or a service out there that does this

I have Focam and Trendnet cam's
