Designed for 24/7 Surveillance

The S300 is designed to run reliably in demanding surveillance environments, supporting workloads* of up to 180 TB per year7 and MTTF of up to 1 million hours8 to help keep your security system running 24/7.

* workloads vary by capacity

Optimized Performance

Record and stream high definition videos at lightning-fast speeds reliably with up to 10TB1 storage capacity - allowing you to store more high definition footage and more high quality frames per second. The S300's large cache size (up to 256 MB)* and fast data transfer speed (up to 248 MB/s9)* help minimize frame loss and improve video playback.

* cache size and transfer speed vary by capacity

Scale with your Security System

The S300 is designed to support up to 64 high definition cameras10*, giving you the flexibility to upgrade and expand your surveillance security system in the future. With up to 10TB1 storage capacity, you can store more HD videos, enabling longer data retention on fewer number of HDDs.

* number of cameras supported varies by capacity

Built to Last

The S300 utilizes RV sensor technology to compensate for the effects of vibration from adjacent drives or cooling fans in a multi-bay enclosure. It is designed to operate in a wide temperature range and maintains durability even in harsh operating environments.
