Coaxial Transmitter & Receiver - Ethernet Over Coax, 1Pair 10/100Mbps, Passive IP Network Extender for IP NVR Camera

Eh, despite the 200+ Mbps services provided by ISPs, most streaming services only require less than 30Mbps. ...so 100Mbps is a good service/measure for most. If multiple people are streaming movies, perhaps double...and of course, gamers, streamers and web-hosters may require more...but most don't.This is advertised as an ethernet over coaxial cable adapter for security cameras (with typically 50 ohm impedance coax). I ordered this paired adapters as a hard-wired adapter/converter through the coax in my house (75 ohm impedance, point-to-point, not bus) for a wireless network extender backhaul (with some BNC-F adapters). It works well for that, and connects/transfers at 90Mbps.So ~100Mbps works, for cameras, and ethernet in general, apparently over 75 or 50 ohm cables, but I'd prefer it transfer at at least 1Gbps. Why can't they manufacture similar device with a 1Gbps interface (without the power requirement, size, and latency of MoCa)?Versatility over 50 and 75 ohm impedance cables and affordability...with small size and no external power requirements warrants the fifth star...but I wish these came with 1 Gbps interfaces (without MoCa).May 2024 Update: My run at the time of the original review was about 30 of RG6 cable direct/no-couplers...with 90Mbps. I recently reorganized some things which require that I use these through approximately 100 feet of RG6 with 3 F-couplers and joining F-connectors....and the throughput only dropped to 60Mpbs...still very respectable for unpowered/non-Moca devices.

Utilized in replacing a BNC coax security camera connected to a DVR (not NVR) that had about an 80 foot run and did not want to replace cable. I just used my existing power of the "Siamese" cable for power and then adapted the Ethernet to camera and then other end to router - on same system as my DRV and works great.

Beats running new wire

These are 10Base2 interfaces to permit digital signals to be passed over RG59 cable. Speed will be limited to about 10Mbps. Will not support 100BaseT or Gig ethernet without delays and buffering. Has BNC female connectors, requiring BNC male to F female adapters for connection to standard video RG59 F-male connectors. Small and passively powered may attenuate signal strength over longer distances. Uses four of the 8 available positions in the RJ45 connectors, which also implies limited date speed rate. Seemingly well made. Short RJ45 cable ends are a bit thin and may be compromised by excessive strain or repeated bending.

Works great for a passive IP encoder for RG59 coax.
