ESP8266 Wifi with more than 1 listening TCP Port

Please assist, I have multuple Ip cameras that will send an alarm using TCP, it works very well with this using one WiFiServer server(port), but I'm not sure how to add a second listening port (WiFiServer server2(port2)) ?

The amount of data sent is only about 100 text characters.

you don't need an additional port. all clients can send data to the same port.

Ok so even if they send at the same time it should not be a problem?

no problem
