What kind of cpu specs does it take to record multiple 1080p from webcam?

Well long story short, I am trying to catch someone vandalizing cars outside my apartment complex. Currently my setup is cheap ( as i am not the owner and can not put up real camera's). I have one camera recording via a laptop and steaming to my nas, I would like to add another webcam so i can cover more of the parking lot, but I have limited recording options on a mac, and every time I start a new recording the files seem to "hang" for 30 seconds or so. ( I only restart it once its hit 12 hours so I dont have to pan through a full days worth of footage if nothing was damaged).

 

I am considering building a budget pc for this purpose (as i personally already have over 2k in paint damage and i would just love to catch the person responsible).

Would a 2.5ghz dual core work for my purposes? I already have the storage end covered with a 5.4TB nas with a 240 GB ssd cache so saving the files is no problem. I just need to be able to record them with 0 frame loss. 

 

Or would i be better off just going the route of a traditional security system that comes with cams? ( i have seen them around $200-500 on ebay, and i would just go with the cheapest one with infrared cams

 

Edit:

The reason i cant use my current system as it is a mac and really lacks recording features that support webcams, and you cant multi record.

 

Edit2:

Cam quality day/night

I don't know how to tell you this but i feel as this is pointless. Get a security kit and use that t would be better and where are you setting up the cameras can you even get the guys face?

ya, its surprisingly good quality considering the conditions. I uploaded some sample pics

If you can get a really cheap camera and put it in your car you might have a better chance just don't put a laptop or something in there.

the only other thing i considered is that the key marks/ scratches are kid height, so they might not even be seen from the car cam ( i drive the truck )

edit: and my windows are 10% grade tint, so that would also limit the camera quality at night which is when I think it is happening

If it's a kid, simply printing out an official looking sign saying "This vehicle is under surveillance" and sticking them on the cars might work.
