Depends how you want to look at it. From zero to what I have now, a bit.
This is because the house has been fully wired with Cat6 back to the store room where I have a cabinet.
If you don't include that,
2x Geovision's @ $550 a piece.
1x DLink Gigabit PoE managed switch, $400
1x Slim PC from work $free
1x XProtect S/W Licence, $free (for everone) - Search XProtect Milestone System
1x Day of tuning the software, motion detection, 3G access etc.
Got Prospeed electrical to do the ethernet runs for me.
Call it around $1700, but all done properly, and all works awesomely well with all the cool features.
Prior to that I had about $2000 worth of Cat6 wiring done throughout, and the rack etc.
If anyone needs any help or advice, drop me an email
My completed cabinet after all done:
