Review on 🔌 Anmbest 5PCS M22Z Shielded RJ45 Waterproof Cat5/5e/6 8P8C Connector IP67 Ethernet LAN Cable Connector Double Head Outdoor LAN Coupler Adapter Female to Female for Enhanced SEO by Chris Nonamaker

I bought these more expensive units because of the good reviews saying they were waterproof. After the first rain, my camera stopped responding. After checking all the connections, this "watertight" coupling was full of water. It looks like it will go through a compression sleeve. They go through POE as long as they stay dry.
