I used this item to attach my Camera DVR to my TV. NO power supplies needed is a big plus and I ran about 75ft of Cat6. It works perfectly.

Rated 4 out of 5

Good quality VGA over 50m of CAT5

Replaced a failed Kramer unit with similar performance. Needs power at both ends. Kramer sent power over the CAT5, so only needed power at one end.

By nivek

I used this item to attach my Camera DVR to my TV. NO power supplies needed is a big plus and I ran about 75ft of Cat6. It works perfectly.

What sets the StarTech VGA Video Extender Over Cat5 apart is its ability to extend your VGA video signal up to an impressive 500 feet (150 meters), enabling you to connect to as many as four displays (two local and two remote) from a single source. This comprehensive kit includes both a local transmitter and a remote receiver unit, providing a complete solution for situations where remote monitor displays are necessary.

The local unit is equipped with a single VGA input and two VGA outputs, allowing you to view and split your source VGA signal to two independent displays locally. This high-quality VGA video signal is then transmitted over standard 4 pair Category 5 or better UTP cable to the remote unit.

The remote unit also boasts two additional VGA outputs, offering you the flexibility to display your VGA source on up to four monitors in total. This makes it an ideal choice for multi-display setups in professional or home environments.

To ensure easy installation, the package includes a mounting bracket for the ST121UTP receiver. This provides versatile mounting options, allowing you to securely install the unit on a wall, desk, or inside a cabinet.

Whether you're connecting a computer, camera DVR, or other VGA-output device to a distant display or projector, the StarTech VGA Video Extender Over Cat5 delivers reliable, high-quality performance. Its durable construction, ease of use, and affordability make it a top choice for extending VGA signals over Cat5 cables.

StarTech VGA Video Extender Over Cat5 Up to 500' Features

  • Consists of 1 Base unit for the local display and 1 Remote unit for the remote display (up to 2 monitors can be connected at each location)
  • Uses standard Category 5 straight-wired, twisted-pair, network patch cable for economical and reliable data transmission
  • Place the display in a convenient viewing area, while the system equipment is placed elsewhere in a clean and secure environment
  • Ideal for digital signage applications in financial, educational and business sectors
  • Extend your display across harsh environment industrial sites
  • Perfect for video conferencing solutions in boardrooms and office settings
  • Optimize placement of your demo stations at tradeshows and in auditoriums
