Do I need to set up DDNS with my Hikvision system?

[macman]

Q1. Do I need to set up DDNS if I only want to access my system on the local LAN? I'm not yet able to persuade my shiny new Hik video intercom to see my other IP cameras or to sync with the network time clock so wondering if I need to broadcast to the internet.

Q2. If I have a static IP would I want/need to set up DDNS?

DDNS would only be useful for remote access i.e. when you are away from home.
And, as you say, if you have a static IP address then you do not need DDNS to find your system on the world wide web.
