NVT Phybridge NV-842 8-Channel Active Receiver Hub
The NV-842 is an 8-channel active receiver hub designed for security integrators and system installers who need reliable video transmission over UTP cable at extended distances. This StubEQ active hub delivers full-motion monochrome and color video up to 2,000ft (600m), making it ideal for large-scale surveillance deployments where traditional coaxial runs are impractical or cost-prohibitive. Using NVT Phybridge's proprietary StubEQ technology, the NV-842 provides adaptive equalization that automatically compensates for signal degradation, ensuring consistent video quality across all eight channels without manual calibration.

Frequently Asked Questions
What is an 8-channel active receiver hub and how does it work?
An 8-channel active receiver hub like the NV-842 is an amplified video distribution device that receives video signals from multiple sources and amplifies them for transmission over long distances. The active receiver hub compensates for signal loss that occurs over extended cable runs, allowing you to transmit video quality signals up to 2,000ft without degradation.
How far can the NV-842 transmit video over UTP cable?
The NV-842 can transmit full-motion video up to 2,000ft (600m) when using NVT UTP cable. This extended transmission distance makes it suitable for large facilities, multi-building campuses, and complex surveillance installations where traditional coaxial solutions would be cost-prohibitive.
What is StubEQ technology and why does it matter?
StubEQ adaptive equalization is NVT Phybridge's proprietary technology that automatically adjusts signal levels to maintain video quality across all eight channels. Unlike manual equalization systems, StubEQ requires no technician intervention — it continuously optimizes performance in real-time, ensuring consistent video delivery regardless of cable conditions or environmental factors.
Can the NV-842 handle both color and monochrome video?
Yes, the NV-842 supports both full-motion color and monochrome video transmission across all eight channels, providing flexibility for mixed surveillance environments with different camera types and legacy system integration.
