Yes, the kit comes with 60ft BNC cables (with attached power). The DVR can reside anywhere inside you wish, but keep in mind it needs a hardline network connection to utilize the web based functions (remote viewing and email).
You’re also going to want a computer screen or television attached to it so you can setup the DVR and view your camera feeds.
I have been looking for a security camera system - almost pulled the trigger on this system but found this at the costco site –http://tinyurl.com/m4lfg2k -
A much better value which includes 4 x 700 TVL cameras, 2 x 100 ft. & 2 x 60 ft. cables.
Your welcome
