I'd say self contained system cctv, & bridge between buildings with wifi to view both systems on the cleint software.

I would probably use a stand-alone system for your new units and set them up on the network so that you can view the cameras from your PC or laptop from your existing unit.

If it is possible to run a cable, run a CAT5 down and then power locally ??

I always try to avoid wireless if i can

.... and if you were to go wireless i would use a wireless transmitter and reciever ...NOT a wireless camera. You could even use a stand-alone DVR with 4 cameras and a monitor. Then use the output from the monitor to one transmitter.....then the reciever to a monitor at your existing unit viewing all 4 cameras.

..another option is to cable a CAT5 from building to building at high level (like BT)
