Ethernet over coax adapters with PoE enable replacement of analog camera systems via existing cable infrastructure

EqcoLogic is shipping its Ethernet over 75-Ohm coaxial cable adapters for IP camera and networked video recorder (NVR) systems.

BRUSSELS & DALLAS -- EqcoLogic announced that it is shipping its Ethernet over 75-Ohm coaxial cable adapters for IP camera and networked video recorder (NVR) systems. The adapters consist of a transmitter (master) and receiver (slave) set, which send Ethernet signalling over coaxial cable with Power over Ethernet (PoE) and Power over Coax (PoC) support.

The adapters -- the FastECoax7501M and FastECoax7501S -- use EqcoLogic’s EQCO875SC transceiver circuit, enabling full duplex 100BaseT communication together with power transmission over a single coaxial cable. The adapters support up to 240 meters of coax cable, depending on type and quality.

EqcoLogic’s Ethernet IP adapter is intended for use with industrial and security cameras where IP cameras and Network Video Recorders (NVR) have rapidly growing shares of the CCTV market. Normally, an IP camera using CAT 5 cable can only support lengths up to 100 meters. With the EQCO875SC circuit, long haul connections can be made using pre-existing coax infrastructure. This allows the conversion of existing analog camera and video server systems (using 75 ohm COAX cabling) to digital with no need to re-install cable.

“One of the barriers to IP camera and NVR adoption is the requirement to change out cabling from coaxial to CAT5/CAT6. There are millions of miles of existing installed coaxial cable used for analog cameras and digital video recorders (DVR). We are enabling IP camera system installers to utilize existing coaxial cable without having to incur the expense to change out cable to add digital capability,” said Zeph Freeman, VP Business Development for EqcoLogic. “Our solution allows NVR (and Hybrid) systems and Ethernet switches to send PoE and PoC for powering remote cameras and devices.”

EQCO875SC supports key protocols including Ethernet (fast and gigabit), IEEE 1394b (Firewire) and LVDS. Markets include security, industrial, automotive and factory automation where the EQCO875SC enables high performance and low cost networking with coax cables. The FastECoax7501M (Master) and the FastECoax7501S (Slave) are priced at US $88.00 (US $176 for the pair) for small order quantities. Volume discounts are available. For more information, visit:
