For analog cameras, you can use one pair of a 4-pair CAT5 for each camera. Run the four pair from the DVR to either the closest camera or a mid-point between cameras. Then splice additional CAT5 cables out to each camera from there. You could even run a 4-pair with all 4 cameras to the first camera, splice the remaining 3 pairs out to the second, splice two of the pairs onto a 4-pair from there to the third camera, etc. Splices can be done using beans or IDC splices (Telco). For analog video, it is not absolutely necessary to use punchdown blocks. Just try to maintain twist as much as possible.

 

The biggest issue there is power. If you run separate 18/2 power for each camera, you could follow the above method. However, if you want to run power for the cameras on the same UTP as the video, you will not be able to run 4 cameras on a single 4-pair. Most likely, you would need one 4-pair per camera, depending on total distance from power supply to camera.

 

For IP, look at the NVT EC1701U devices. They can run up to 4 IP cameras on a single 4-pair, with POE, depending on distance. Here is a link: http://www.nvt.com/content.php?type=template&key=productfamily&ckey=eo2
