A technician needs to install an IP-based camera in a remote location. The technician runs a Cat 6 cable to the location and connects it to the camera. Which of the following is needed for the camera

The correct answer is C. PoE switch. An IP-based camera in a remote location connected via Cat 6 cable requires a PoE (Power over Ethernet) switch to receive both data connectivity and electrical power over a single cable.

Why each option

An IP-based camera in a remote location connected via Cat 6 cable requires a PoE (Power over Ethernet) switch to receive both data connectivity and electrical power over a single cable.

AUSB to Ethernet adapter

A USB to Ethernet adapter is used to provide Ethernet connectivity to a device that lacks an Ethernet port, which is not applicable here as the camera is already connected via a Cat 6 cable.

BDVI cable

A DVI cable is a digital video interface used for display connections and is not suitable for transmitting network data or power to an IP camera.

CPoE switchCorrect

An IP camera needs both network connectivity and power to operate. A Power over Ethernet (PoE) switch is specifically designed to deliver both electrical power and data over a single Ethernet cable (like Cat 6), eliminating the need for a separate power supply at the remote camera location.

DH.261 codec

H.261 is a video compression standard (codec), which processes the video data, but it is not a physical component or power source required for the camera's basic operation.
