What's the point in rack mounting your DVR if you can't rack mount the cameras' power supply. Great idea, however I must admit it is a little more expensive than a 16 channel power box supply.

This is a nice way to keep your installation neat and tidy. This rack mounted power supply also gives you the ability to place your power supply somewhere where it won't be in the way and subject to bumping and knocking around (like laying it in a corner somewhere or trying to mount it on a wall in a server room that has very little available space, other than on the rack). Just one word of caution: This is not a network switching power supply for power POE (Power Over the Ethernet) applications it is simply a 12 volt power supply that is within a server type case that can be easily rack mounted.
