Product Features
Engineered for mainstream surveillance systems: Designed specifically for surveillance use, this drive fits the needs of everyday recording setups. It is built to handle the steady, continuous nature of video capture. That means you can focus on monitoring and reviewing footage without worrying about whether your storage is suited to the job.
WD AllFrame technology for surveillance workloads: WD AllFrame technology delivers optimizations for write-intensive, low bit-rate, high stream-count workloads typical to mainstream surveillance applications. In real use, this helps the drive stay aligned with how surveillance systems actually write data. The result is storage behavior that matches the demands of multi-stream recording.
Supports higher workload and multi-bay setups: Supports up to 180TB/yr workload rate and up to 16 bays for systems that need room to grow. This makes it easier to scale from a smaller setup to a larger recorder without changing your storage approach. With multi-bay support, it can fit into more robust surveillance configurations.
Built for multi-camera compatibility: Compatibility includes up to 64 HD cameras, helping you record more viewpoints in one system. This is especially useful when you want broader coverage across a home, office, or facility. With support for higher camera counts, you can expand coverage while keeping storage consistent.
