I don't get why people don't get that part. What they mean by "Up to 1234 Mbps" on the box is "1234 Mbps shared". It's a giant wire occupying 1/4 mile around the AP, whereas, in wired Ethernet it's 1Gbps per link per direction.

A GbE switch with wire-rate transfer guarantee can handle 1Gbps traffic between arbitrary combination of ports. All the camera traffic coming from port 9 to 16 going to NVR on port 7 have no impact to traffic between upstream router on port 26 and your PCs on port 3 and 5. That cannot happen with Wi-Fi because everything is inherently on the same shared port 1(sometimes literally); each 4Mbps incoming is 4Mbps of download speed taken from your laptop. Double if destination is also on Wi-Fi.

This might be fine if there's just few cameras, but it's something to be aware of.
