This step is very important, as this is how entry data is able to be displayed for a site (linking your install to a specific site allows you to get access to Analytics and Visual Insights).
Installs are also used to facilitate searching and sorting cameras.
In order to link your install to the site, log into your account at app.prism.com.
Navigate to the "Settings" tab within Prism's Web Application.
Navigate to the "Sites" tab - > Click on "Site name" link - > Click on "Edit this site"
In the "Installs"field, start typing the name of your new camera and press Enter once you see it.
You can link as many installs to a site as you need.
Then click the "Save" button. You're all set!
