Monthly use in GB's depends on a number of factors and variables. For example, the number of cameras used for recording is just a part of the equation. We recommend WiFi service with unlimited data.
We have conducted several tests and determined average data usage for our camera based on the quality of the stream and permanent usage over a month (720 hours). The actual usage may be lower or higher depending on various factors. On average the camera will use:
Low = 50 GB / month
Medium = 200 GB / month
High = 600 GB / month
