Local recording capacity heavily depends on the number of cameras, frame rate, resolution, amount of motion in the scene and ultimately the average bitrate.

You can check the current recording capacity by going to to: Admin > TetherBoxes > TetherBox Name. You will see all storage devices presently connected to your TetherBox under the "Storage" tab:
​

You can also see the current capacity in the TetherBoxes table under: Admin > TetherBoxes.

The TetherBox Giga comes with around 4 weeks of capacity on average, however this depends on the factors listed above.

For example, a TetherBox Giga with 20 x 1080p cameras will have around 4-5 weeks of capacity with low amounts of motion, whereas a TetherBox Giga with 20 x 4k cameras with moderate motion will have about 2 weeks of local capacity.

You can order the Giga and Pro units with additional storage, or you can add additional storage after the fact. Giga/Pro units come with 4 x SATA ports in total, with only 1 populated as standard. You can add 3 additional 3.5" SATA drives or contact TetherX to order a unit with a custom amount of local storage.

The TetherBox Pico has around 2 weeks capacity on average, however this depends on the factors listed above.

For example, a TetherBox Pico with 5 x 1080p cameras will have around 3-4 weeks of capacity with low amounts of motion, whereas a TetherBox Pico with 5 x 4k cameras with moderate motion will have about a week of local capacity.

Information how to expand the local capacity can be found here: How do I expand the local recording capacity of the TetherBox?

Our smallest unit, The TetherBox does not come with any built-in local storage, you will need to connect external storage. Please see more details here: Why does The TetherBox (5 channel) require an external drive for video surveillance?
