The NVT Model NV-EC1701 Ethernet over Coax EoC Transceiver is a compact media converter that allows 10/100 BaseT Ethernet and PoE power to be transmitted using coax cable. These EoC devices are typically used in legacy installations where existing coaxial cable is re-deployed as part of an upgrade to IP cameras. 48VDC class 2 power is delivered to one transceiver, which distributes it to up to four remote transceivers, and their PoE cameras.
These transceivers are extremely simple to use, with no IP or MAC address configuration required. Status LEDs indicate power and link connectivity/activity for RJ45 and BNC ports.
The NV-EC1701 is backed by NVT’s award winning customer support and limited lifetime warranty.

NV-EC1701 - Features
Transmits 10/100 BaseT Full Duplex Ethernet up to 1,500m (5,000ft)* over RG-59 (or similar)
Powers PoE cameras (or other PoE devices), up to 45 watts
One EoC transceiver at the network-end can support up to four remote transceivers/IP cameras using BNC “T” adaptors
48VDC from one power supply is distributed over the coax to all connected equipment
Transparent network ‘plug & play’ connectivity; no configuration or setup required
Supports all networking protocols (UDP, TCP/IP, HTTP, etc.)
Advanced transmission and power technology with built-in transient protection
Available in 1-4 Camera System Kits
Limited lifetime warranty
Note *Distance and number of devices supported will often be lower due to power delivery voltage-drop on the cable. See Cable Distance Chart.
