StarTech.com ST121UTP VGA Video Extender over Cat5 (ST121 Series) - Up to 500ft (150m) - VGA over Cat 5 Extender - 2 Local and 2 Remote

The StarTech.com ST121UTP is a VGA-over-Cat5 extender for sending video to up to two local and two remote displays, making it suitable for offices, classrooms, or other setups that need VGA screens in separate locations. It supports up to 500 ft (150 m), with resolution depending on distance.

Recommended For

• Security or facilities teams with a VGA-output DVR can use it to mirror live camera feeds to a lobby or other remote monitor over an existing, dedicated Cat5e-or-better cable run. A Best Buy customer review describes this setup over about 100 feet of Cat6. ([bestbuy.com](https://www.bestbuy.com/site/reviews/startech-vga-video-extender-over-cat-5-kit-black/1262492))
• Office, school, church, or event AV teams with a VGA source can send the same presentation image to local and remote displays, such as monitors in different parts of a room or venue. A customer review describes using it for multiple large-screen PowerPoint displays. ([bestbuy.com](https://www.bestbuy.com/site/reviews/startech-vga-video-extender-over-cat-5-kit-black/1262492))
• Schools, businesses, and venue operators with VGA-based signage or presentation equipment can use it when the display needs to be positioned away from the source and a direct Cat5e-or-better cable run is available. StarTech lists signage, boardrooms, auditoriums, and trade-show demo stations as intended settings. ([media.startech.com](https://media.startech.com/cms/pdfs/st121utp_datasheet.pdf))
• AV or IT installers who need one VGA source shown on up to two local and two remote displays can use the extender to distribute the same image across both locations. ([media.startech.com](https://media.startech.com/cms/pdfs/st121utp_datasheet.pdf))

Real-World Use Scenarios

• A hotel or shop keeps its VGA security DVR in an office but wants a live camera view at reception; the extender carries the same feed to a lobby monitor over an existing Cat5e-or-better cable run.
• A church presents slides from a computer and wants the same image on several VGA monitors around the room; the local and remote outputs can distribute that image to up to four displays.
• In a boardroom, the computer can stay near the presenter or in a cabinet while a VGA display or projector is placed where attendees can see it; the video signal travels between them over Cat5e-or-better cable.
• A school or business can send a VGA source to a remote information display while keeping the source equipment elsewhere; this suits basic signage where a VGA connection and the supported resolution are sufficient.
• At a trade-show demo station or auditorium, a VGA source can remain at the control position while a display is placed farther away; the remote output can also feed two monitors showing the same image.
