Buy the cable, ask the electrical contractor to lay, just make sure separate the electric cable and LAN by minimal 6"

Cat5e is sufficient, can run 1Gbps. Cat 6 lots of hassle, can't take tight bend.

I wonder where you get this information? Cat5e are able to go at 1000Mbps max length 100meter. That is the reason it called Cat 5e (enhance)

Say using 100Mbps speed data transmission, assuming conventional house PC equipments able to handle such high bandwidth

- 100Mbps / 8 = 12.5MBps (Mega Bytes per sec),
- 12.5Mbps - 20% (Max overhead) = 10MBps
- 10MBps x 60 = 600 Megabytes per min
- 600MB / min x 60 = 36,000 MB / hours

So you think 36 Gig per hours enough for Full HD? Even run at 1/2 the speed you get full HD for one movie.


FYI, technically Full HD is 1920x1080, = 2,073,600 Pixels , using 2bytes per pixels 32bits color , you get 4,147,200 Bytes / sec. Voice will not be that much maybe 1MB / sec. Which add up to about 5MB per sec maybe 6MB per sec. This are all without compression, and most transmission come with video and voice compression which will reduce the size.

So you think Cat5e enough? even at 100MBps is already enough. Most important, use good quality cable.


Cat 6a is rate to go up to 10Gbps (theoretically)

In some of my office, we run Cat 5e with 1Gbps without any problem.

Then better put fiber.

Because copper have limitation and noise, at 10Gbps and the frequency you get lots of noise interference. Fiber can go up to 1000Gbps, no less noise problem, and not afraid of Lighting. Please get single mode fiber .

Yes better put PVC conduit cause LAN cable do not have thick outer core, unless you get the specific LAN that do that. CCTV RG59 , is prefer to be 12"
