When viewing remotely, IP cameras on a cheap switch connected to a router are very slow. Will changing the switch help?

Question

Computer networks

Hello.

Remote viewing of cameras is required, the channel is rather narrow (up to 4 Mbps). Cameras that are connected to the ports of the router work tolerably (small slowdowns every 20-30 seconds). Two lan switches are connected to the router for $ 10 (100Mbps TP-link, but in the home local network they work fine with the same IP cameras). The cameras that are connected to these switches frenetically slow down and hang every 5-10 seconds for the same period of time. I lowered the image settings to the very minimum, bitrate 512kb, minimum resolution and 6 frames per second. And even with 1fps, they manage to freeze every minute for 10 seconds. The cameras that are connected to the router (there are only 2 of them, there are 4 ports in the router) also work with low quality settings (but a little better - 1024 kb, 20 fps, 720p). All cameras work through the router's NAT.

Tell me what's the matter - in cheap switches, a narrow channel or something else?

Answer 1

How many cameras are there? Two? Or more?
Go to each camera by IP and do a full reset, reconfigure it, set a password and see how they behave further.
If there is a registrar, do the same procedure ..

Answer 2

what about the switch?
ring the network for underpressure, breaks.
the switch can be checked by replacing it with a home one, in fact ...
