Setting up TCP Communication

  • PDF

Article summary

The camera can work with Node-RED and TCP to communicate with other devices. It's quite simple; the steps are:

Step 1 :

- The camera's IP address must be in the same range as the device it is interacting with.

Step 2 :

- A communication port (TCP in) must be opened, where we assign the port we will be listening to.

Step 3 :

- To send a response to the port, we need to place a TCP out node, assign the IP address of the device we are communicating with, and assign a free port.

Example:

Node Red Logic:
