I had service installed last Friday afternoon (Liberty 10) at a weekender house that we purchased. We used the service two days, only internet surfing, no streaming and left early Sunday afternoon. I went on Excede website Wednesday and saw that 6.3MB were already used of the 10, which was surprising for two days. Four of us share 15 on cell phone and have never exceded that amount in a month. On Thursday I checked and 8.3 were now used, even though no one has been at the house since Sunday. This morning I checked again and it is up to 9.1. The only thing I can think of is a small nest camera I installed for security, but that should not suck that kind of data usuage.
Is this typical for this company?
On a limited satellite (or any other severely capped internet service), the reasons against would be identical to those for mobile Wifi:
Some of these cameras only upload video when they detect motion (instead of streaming video 24/7 -- which would be like watching Netflix 24/7), so it's always good to check the settings and adjust them to reduce "false positives" for motion, such as limiting the area in the picture that the camera is sensing motion. But, since they're all designed to store video in the cloud instead of locally, they're going to consume vast amounts of bandwidth.
The best option is to switch to cameras that don't use the cloud. These aren't "turnkey" like a Nest Cam -- they require more work and technical know-how to set up -- but they'll use significantly less bandwidth. I have a cabin and have 12 network cameras set up around the property, and I've set up my router so I can connect remotely to view the cameras whenever I like. They're not normally streaming data over satellite internet unless I connect in, and then just for a few seconds or a couple minutes while I check on things. But they are always recording data locally -- I use software on a Mac Mini designed to do this. You can have the software send you an e-mail when it detects motion, which takes a lot less bandwidth than having it constantly upload the video to the cloud. So, if I receive an alert, I can connect remotely and then view the video clip, only using my satellite data at that time. This worked fine even when I was on a 10-GB plan.
Again, setting up network cameras with a local server and configuring your router to connect remotely is more expensive up front and requires more skill, but if configured properly it won't suck up your bandwidth and you'll also save on the monthly fees associated with the cloud-based, simpler cams.
