A limited supply of DECA-200-10M is available at a lower price of $39.98 per set than Dualcomm DECA-200 PoE-over-Coax Adapter Kit. DECA-200-10M works reliably at 10Mbps which is more than enough for most high-resolution IP camera video transmissions. It is recommended to use DECA-200-10M with a PoE switch or NVR that can be manually configured to operate at 10Mbps (auto). 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)
