| General tips for installation: |
- Ensure the site has access to a strong 3G/4G/LTE wireless internet service.

Other options
In some areas, the wireless internet service may not be adequate and an alternative connection to the internet must be used.
An ADSL connection is a common option for long-term installations. An ADSL router can provide a wired (Ethernet) or wireless connection for the NEX controller.
