IP Migration Without the Migraines

Ethernet over coax (EoC) enables more installers to approach IP migration projects with a new set of financial and installation options. An EoC solution’s elegance is its simplicity of design and application – and everyone saves money.

Ethernet Distance Issue — With Ethernet/PoE, repeaters must be installed every 328 feet. For the installer, that typically means sourcing power in odd locations throughout the facility, in order to create a proper repeater data/power supply point. This usually involves a lockable closet that has no power mains installed, so now there is the cost of installing a power plug/mains. A camera at 750 feet requires two repeaters. These repeaters, their associated connections and the typical need for uninterruptible power supply (UPS) power all add up to being a potential remote point-of-failure headache.

With the EoC-based PoE, 56VDC power is provided at the control room, and is distributed to the EoC transceivers and the IP cameras. There are no repeaters and the problem is solved without impacting the budget.

Many IP cameras can get power from the existing 24VAC distribution system. However, PoE adds value, increases customer options and can simplify the design. With EoC-based PoE, cameras can operate from the same UPS as the control room equipment.

Simple Installation, No Software Settings Needed — EoC provides an easy-to-connect, transparent network that is very simple to use, reliable, and affords seamless integration between existing coax cable and the Ethernet backbone. To provide utmost signal integrity and security, the EoC network must be configured to communicate exclusively with other transceivers within their network group.

A network group typically consists of one EoC transceiver located in the control room and up to four EoC transceivers at the IP camera or remote IP device. EoC supports network protocols such as UDP, TCP/IP, HTTP, etc.

Eco-Friendly Green Choice — Not having to recycle the analog network’s coax and not having to use carbon-based products and copper to manufacture the UTP is good for the environment. Also, fully leveraging one’s initial investment in the coax infrastructure supports that initial capital outlay.

Facility Disruption Dramatically Reduced — Extended-distance Ethernet enables the end user to choose when they would like to start the migration and install IP equipment, because the process can be done incrementally. This allows the end user’s operations to control the impact on its work schedule. In the case of hospitals for example, this minimizes the disruption of service to patients. Or in a gaming application, it allows gaming tables and machines to operate within the gaming authority’s surveillance guidelines.

In sum, the elegance of an EoC solution is its simplicity of design and application. Installation is easy, data is robust and reliable, and everyone saves money. EoC technology will enable more installers to approach an IP migration project with a new set of financial and installation options.
