Is there any agreement or contract we have to sign if we were to install it?

There is a simple expectation form.

The form basically states that…

1. You agree to keep it on and will work with us to get it back on if it goes offline
(so we don’t have to come out if it just needs to be plugged back in, or switched on, etc.).

2. If too many campaigns are rejected, or you fail to keep it running we will probably come remove it. It remains our property but it’s free for you to use and you aren’t liable, etc.
