We are installing a centrally monitored, wired alarm system in our
house.

I noticed that the Network Interface device sits unprotected at waist
level on the outside of the house. Even more concerning, the phone
line enters and exits the box unprotected.

Other than paying for a radio link backup, what is the best way to
"harden" the phone line?

- Would it make sense to encase it in electrical conduit at least
until the wire is out of reach?

- If so, What type of conduit and fittings should one use so that it
is both sufficiently tamper-proof and weather resistant?

- Any other suggestions?


Generally threaded iron pipe is used, though normal EMT conduit should
be okay. Most monitored systems respond in the phone line is dead,
and an external alarm bell can be used as well. The best is a
cell/radio backup of course.
