# Are the CV30 camera cables plenum rated?

The cables supplied with Nureva® CV30 cameras **are not plenum rated**. For installations that require plenum-rated cables, it’s recommended material/cabling is used in accordance with the applicable national, regional and local electrical codes or ordinances.

## What is a plenum?

A plenum is an air-filled space within a structure. The most common type of plenum that Nureva devices are used with is the open space above the ceiling.

## What does plenum-rated mean?

Air travels throughout a building via plenum spaces, constantly circulating. With this circulation, there is the potential for smoke or toxic fumes to move through the plenums of a building. *Plenum rated* means that the cables are designed to meet a specific standard to restrict the spread of fire and limit the amount of smoke or fumes emitted during a fire.

## Plenum-rated USB cable or plenum-rated Ethernet cable?

The CV30 camera kit provides a powered USB 3.0 hub and a 32.8' (10 m) USB 3.0 extender cable. The hub and extender cable support a 4K video stream and power delivery up to 600 mA at 5 V. This extender cable is not plenum-rated.

For installations that require running the USB cable through a ceiling (plenum), one of the USB over Ethernet solutions that we have tested is recommended. The Ethernet cable between the transmitter and receiver would be a plenum-rated Ethernet cable. Plenum-rated Ethernet cables are easier to find. Further information about USB extender requirements is available in the article below.
