[Rubens 0]

Hi..

 

I’m a total newbie who wants to upgrade my friends 5 years old CCTV in two different garages.

Line of coax is no longer than 50feet. Ip cameras is not going to happen with wiring.

There are two types HD-SDI solutions we are wondering about.

A

1 pc HDI DVR http://www.kingdisplay.net/products/347.html 800USD

4 pc Cam http://www.kingdisplay.net/products/351.html 300USD pc

B

1 pc HDI DVR http://www.cctvcameramall.com/index.php?route=product/category&path=33_43 900USD

4 pc Cam http://www.cctvcameramall.com/index.php?route=product/product&product_id=410 203USD

 

What would you have choose of this ones? A or B?

Or maybe I do totally wrong and should buy from somewhere else?

 

Thanks, from Norway.
