Q: Are the ethernet cables rated for outdoor use?
A: Hi Aguo. For better longevity and security we would recommend that you protect the cables by installing them in a roof/wall space or putting them inside conduit. Each cable includes a weatherproof cover to seal the connections, but it is best to keep the cables covered where possible. -SD, Swann team
