Electricians visited today to run Cat-6 to my Reolink WiFi doorbell. Much like the Hikvision and EzViz doorbells before it, the WiFi performance/stability was seriously bad. The front exterior wall is wood planks over wood studs, the interior is drywall. Nothing there to inhibit the WiFi signal strength, whatsoever. Yet all three pieces of hardware would drop the WiFi signal multiple times daily. I moved the WiFi access point multiple times, yielding no improvement whatsoever. I think the original Hikvision would fail less than five times every day. The EzViz would fail thirty and forty times daily. This Reolink was about 50/50 on staying connected or not. Rather than buying and installing a new Reolink PoE doorbell, I got Ethernet cable run to the RJ-45 Ethernet jack present on the WiFi doorbell. A few configuration changes, a few doorbell reboots, and a few router reboots later, and it's now finally running with a rock-solid wired connection.
