Use a Coax Cable to Extend Ethernet Range

Connect any TCP/IP device to another component located a long distance away using the Seco-Larm Enforcer Passive Ethernet Extender Over Coax. This two-piece set allows you to create an Ethernet cable run longer than the standard limit of 300 feet. As shown in the diagram below, each device connects to one of the two extenders using two Ethernet cables, one for each. The two extenders then connect to each other using a coax cable, completing the extended connection between components.

  • Extends Ethernet cable range for connecting TCP/IP devices
  • Supports 10/100 Mbps transmission rates
  • Easy to install, no power required
  • Consists of two bidirectional transceivers
  • Built-in surge protection on both ends
  • Designed for 10/100 networks. Do not use on "gigabit" 10/100/1000 networks.

The set of extenders supports both 10Mbps and 100Mbps speeds. At 10Mbps, you can extend the transmission distance up to 650 feet. At 100Mbps, the maximum distance is 325 feet. The extenders do not filter out any protocols, codes, or applications, ensuring compatibility with any IP camera and its software.
