Dualcomm's patented DECA-200 Ethernet PoE-over-Coax Adapter Kit is a first of its kind in the industry that enables transmission of both full-duplex 10/100Base-T Ethernet packets and inline power of PoE (Power-over-Ethernet) over a 75-ohm coax cable. 

The DECA-200 PoE-over-Coax Adapter Kit provides a very cost-effective way to migrate an analog video surveillance system to an IP camera video system by utilizing previously installed coax cabling. It allows you to replace analog cameras with IP cameras at your own pace as each DECA-200 PoE-over-Coax Adapter Kit can be installed independently.

DECA-200 includes two adapters (DECA-200A and DECA-200B), one adapter for connecting to a Powered Device (PD) such as an IP camera at one end of a coax cable, and the other adapter for connecting to a Power Source Equipment (PSE) such as a PoE enabled Ethernet switch at the other end of the coax cable. 

Either DECA-200A or DECA-200B can be used to connect to a PD. For connecting to a PSE, DECA-200A should be used with a PSE of “Mode A” as defined in the PoE standards 802.3af/at, and DECA-200B should be used with a PSE of “Mode B”. 

A special kit DECA-200-24V is available for use with the proprietary passive 24V PoE system which includes two DECA-200B adapters.

A limited supply of DECA-200-10M is available at a lower price of $39.98 per set. DECA-200-10M works reliably at 10Mbps only which is more than enough for most high-resolution IP camera video transmissions (up to 8MP). It is recommended to use DECA-200-10M with a PoE switch or NVR that can be manually configured to operate at 10Mbps (auto). DECA-200-10M has been tested and confirmed to work reliably with TP-Link's 5, 9 or 18 port PoE/PoE+ Switches in the "Extend Mode": TL-SF1005P (ASIN: B076PRM2C5), TL-SF1009P (ASIN: B08J88BHGK) and TL-SL1218P (ASIN: ‎B0897VX52P)
