The resolution of Motion Sensor data for EPOC is 128 Hz and 12-bits, and for INSIGHT headsets is 64 Hz and 14-bits. The resolution for EPOC+and EPOC X is 16-bits and can be 32 or 64 Hz (or OFF) depending on the headset’s [configuration](../setting-up-your-eeg-device/epoc+-configurations) and whether or not it is connected via Bluetooth. When EPOC+ or EPOC X is connected to Bluetooth, the rate is limited to 64 Hz. For EPOC Flex, the resolution is 8 bits and the sampling rate is 16 Hz.
