Replace the ADC-SVR122 hard drive
The ADC-SVR122 does have a replaceable drive, but due to its form factor, it is a somewhat involved process. The ADC-SVR122 uses 2.5" SATA drives and supports a storage maximum of 2TBs. The Stream Video Recorder (SVR) can support solid-state drives (SSD), but the benefits are irrelevant to the Stream Video Recorder.
Alarm.com recommends using the 2TB Seagate hard drive (model number ST2000VT000) for replacements. These drives have been tested and ship with the Stream Video Recorder and are specifically made for surveillance applications.
Caution: Using an unapproved hard drive or modifying the device in other ways could void the warranty.
