Any suggestions how to do this that isn't so messy?


Wiremold.


I keep a few pieces of different types of plastic and metal wiremold
in the car to show customers. Most of the stuff came from jobs where
I had to rip the stuff out at the customers request.

None of my customers have ever approved using wiremold.



Whenever possible, i ran it to a corner of the room, then into the
ceiling. I have also removed wood trim along a ceiling and hid wire
under it. I used to do a lot of work in schools and offices. I would
give two quotes, completely hidden, or Wiremold. Sometimes a third
option was to let their maintenance men pull the wire, as long as the
customer signed off that they were responsible for any damaged
materials. I had real fun moving a school intercom console at one
school. The school board had moved their offices to the high school,
and took over the main office. 15 years later, they built a new office
and wanted the main office returned to where it belonged.
Unfortunately, they had added a dozen classrooms between moves, and
there were two, three foot thick foundations separating the two parts.
Luckily, I found an abandoned 16 pair '1A1' phone cable between the two
rooms and managed to find a dozen pairs that were still usable.


The problem
was that they don't want to look at it. For long runs, it had to go
run horizontally along the wall near the floor. That worked fine
until it runs into a doorway. If I was lucky, and they had a hollow
door tread, so I could continue the run (ignoring the awkward
transition around the door frame molding). If not, I was stuck.



Thick baseboards can be pulled, and then saw a notch off the back
with a table saw. I had real fun about 15 years ago. I had to run a 25
pair cable into a new studio at a radio station. The entire building was
cement blocks, and the only way to route the wire was to enlarge
existing holes, with cables already filling them. The station manager
told me it was impossible. He freaked the next day when he came in and
the work was done. then he wanted to know how I cut square holes around
the wires without cutting the existing cables. ;-)


I did use surface conduit once when I installed a structured wiring
system. That's where all the communications cables arrive in a single
neat bundle. Same with cube farms, where individual desks tended to
be isolated "islands" with no adjacent walls. However, none of the
surface wiring was ever wrapped around a doorway.



Good old 'Telepoles'?

If desperate, you could run the CAT5 on the outside of the building.
However, that only works with single wall construction. I'm not very
proud of this mess, but it was the only way it could be done.

I have never done a job that looked that bad. Even for a temporary
install.


I hate to run anything outside, without putting it in conduit and
preferably underground.

He could use a wireless camera with multiple receivers, but that's
still susceptible to causing and dealing with interference. It could
even let a crook see exactly where the cameras are aimed, long before
entering the building.
