New DVR needed - that works with this cams and cables? (PIC)

[Thom 0]

Hi,

 

I have 4 cams already setup and just need a new DVR that can work with them. Hopefully the pic I have included below of the cam and cables will show up ( if not, you can see the pic here - http://imgur.com/a/E4rQN )

 

Am I right in thinking that just about any DVR should work with these cams and cables? For example, if I buy a Swann DVR4-4400 (one of the cheaper ones i've been looking at) could I just plug them in to it and that's that? As these are standard BNC connectors, right?

 

Any advice would be really appreciated. Thank you

 

Thomas
