Part of my job is to setup survellience systems for business.

While there are some advantages of going to IP, its far more expensive than CCTV.

you can have CCTV cameras for less than $200 each, have them all wired to a CCTV card in a computer to which you could remote desktop and view them, also all video is stored on the PC. *shrug*

IP cameras you can access via the network or if you port forward them, the internet.

In RE: Wireless IP cameras, the distance is limited by a few things, including the quality of the cameras wireless attenna and output, the Accee points antenna and output, interference and line of sight obstructions.

A decent N-series Acess Point with a decent camera will run nicely over 30ft if there isnt to many brick/masonary or metal walls in the way, i actually have a wireless camera going alot further and through a whole building still reciving 40% signal and get a nice stream from it.

I also have to disagree with the "more secure via IP", IP is actually hackable via so many different ways, where cctv you would have to actually tap into the cable's signal which cant really be done from outside.

I can recommend the following brands for IP cameras -
Axis , Pixord and IQEYE.

The pixord and IQEYE are more professional, they have interchangable lenses and support Ifra-red very well, allowing you to setup a IR Lamp and see in the dark.

Sharp CCTV Cameras are also great.
