Review cameras with high activity to reduce your subscription costs and bandwidth usage. Adjusting the camera’s position, training, and [zone setup](https://blog.camio.com/extreme-bandwidth-efficiency-with-negative-zones-2a0b93ec56d9) creates significant savings.

**Identify the high-usage cameras**

1. Open your [Dashboard](/content/dashboard/index.html) at [https://camio.com/dashboard](/content/dashboard/index.html).
2. Find cameras with a high number of Events analyzed.
3. Click on an hour in which a high-usage camera produced a lot of Events to see what was happening.

**Remediate with repositioning, training or zones**

1. Use [Negative Zones](https://blog.camio.com/extreme-bandwidth-efficiency-with-negative-zones-2a0b93ec56d9) to mask known-boring regions of the scene with irrelevant Events like passing traffic.
2. Train the camera with a quick thumbs-up or thumbs-down on the Events that are important and not-important.
3. Reposition the orientation of the camera to exclude irrelevant Events.
