Likely causes

Weak Wi-Fi signal at the camera
Upload bandwidth saturated by other devices
Streaming the main high-bitrate stream instead of the substream
Camera overheating in direct sun
Cloud relay or account region adding latency

Quick checks

Check reported Wi-Fi signal strength in the app
Try the lower-resolution stream
Test live view with other devices idle
Compare app performance on mobile data

Step-by-step fix

Move the camera or add an access point closer to it

Set live view to the substream for everyday checking

Cap the camera bitrate or resolution in the app

Update firmware and reboot the router and camera

If lag persists, test with a local NVR or SD recording to isolate the network
