Well the first thing you do is hope that the sheetrock ceiling is dropped so that you can not only go across from side to side, but also front to back. If the sheetrock is up on the beams then there will be a lot of work ahead cutting out all kinds of holes.
Luckily in this installation the sheetrock was not on the beams, but instead dropped down. The best situation for when there is no ceiling tiles to move out of the way. Holes still need to be made, but they can be done so at a minimum.
|In the foreground of the image you can see a square hole that had to be cut|
so that I could fit my hand in and fish the wire to make a turn.
Several other smaller holes were made with a hole saw where wires needed to run.
|There is a crawl space above this ceiling, so all that was needed here|
is the small hole saw hole below the exit sign (barely noticeable)
|Another larger square hole had to be made to get around|
ductwork inside the ceiling.
|To get from the 2nd floor to the 1st Floor a small|
hole saw was used to get inside the walls.
|Unfortunately the first hole came right behind a beam, so a second|
had to be made to get the wall up in the ceiling of the 2nd floor.

|Most of the cameras installed.|
The customers existing DVR was only an 8 channel. and the admin password was locked, so we could not gain access to make changes to that system. The initial thought was to replace it with a 16 channel DVR, but the customer wanted to keep costs to a minimal. So we installed another (cheaper) 8 channel DVR from the same manufacturer so that they could use the same software on their computer to view cameras from both DVRs at the same time. This did increase the cost of the DVR compared to what a budget DVR would have cost, but the benefit is that the customer can access all camera feeds from a single piece of software on their desktop with out needing to switch between windows.
