I have a Eufy hard wired doorbell and find the same as you that if someone rang it, the lag was bad bringing up the feed from the doorbell, although the notification was normally fairly instant. What has helped is enabling the guest WiFi network on my router and only having the doorbell on that. It can still be a bit temperamental, but 90% of the time the lag is gone.
As an aside I have a hybrid 2.5 + 5ghz network, as I suspect many do, with boosters round the house - all supplied by my service provider. I know some home automation kit can struggle on hybrid networks. Be interested to hear if people are still getting lag on exclusive 2.5ghz networks?
