Conduit for Surveillance Explained

Author: Ethan Ace, Published on Jul 16, 2014

Cameras frequently need conduit to protect wires and cables connecting them to the headend / recorder.

However, with so many types available, it is may be difficult to determine the right one to use in each application. 

There are three types of metallic conduit common to surveillance systems:

  • Electrical Metallic Tubing (EMT)
  • Rigid Metal Conduit (RMC or simply "rigid")
  • Liquidtight Flexible Metallic Conduit ("sealtight" or "liquidtight")

Additionally, there are two types of non-metallic conduit commonly used in surveillance:

  • Rigid PVC conduit
  • Electrical nonmetallic tubing (ENT)

In this note, we break down these types, their costs, and where they fit best.
