- A site visit for a port forward
- The site is on 4G or Starlink, behind CGNAT. That is carrier-grade NAT: the site shares a public address with many others, so nothing can be forwarded to it. The port forward you drove out to set up cannot work.
- The control room cannot connect
- You hand a site to the control room, and the first call is that they cannot reach the recorder.
- A camera down nobody noticed
- A camera stops answering, and the first anyone hears is the client, weeks later, asking for footage.
- Nothing to show for the monitoring
- You charge for monitoring, but at the end of the month you have nothing in your own name to show the client.
