Cables: Understanding cable ratings

Your DVR / NVR System will normally include 100ft or 60ft extension cables for easy set up of Lorex by FLIR cameras. If you require cameras to run longer distances, you can purchase additional extension cables. Before purchasing additional cables, it is important to understand how they are certified and rated.

Underwriter Laboratories (UL) Cables

UL Logo

  • The majority of individual extension cables (or 4-packs of cables) sold by Lorex by FLIR are certified by UL.
  • ​​For over a hundred years, UL has provided safety-related certification and testing for commercial and consumer products.
  • UL rated cables from Lorex by FLIR all contain a compliance mark, which identifies the UL certification details. Also printed on each cable is a Valid UL file number. Our cables are certified under FLIR UL file #E470751.

National Electric Code (NEC) and Canadian Electrical Code (CEC) Cables

  • The National Electrical Code (NEC) and Canadian Electrical Code (CEC) classify cables into several different categories.
  • The UL cables sold by Lorex meet the NEC & CEC standards for CMR (Riser) cabling.

Extension Cable Durability and Use

  • In-wall installations: UL rated in-wall cables can be safely run through and inside walls. This allows you to hide them from view and maximize their distance.
  • Fire resistant: The cable jacket material prevents the spread of fire. They must pass a vertical burn test to ensure that the flame will not move along the cable.
  • Between floor installation: Riser cables are engineered to safely run between floors that do not circulate environmental air for heating or conditioning systems.
