Quick guidance

Before ordering, confirm your recorder’s drive size support and bay count. If you want longer retention, higher resolution, or more cameras, consider moving up in capacity to reduce overwrite frequency. After installation, format the drive inside the recorder (not on a PC) so the NVR/DVR can create the correct recording file system. Contact Bear Security Shop if you want help estimating storage based on camera count, resolution, and retention days.

1. Is the WD Purple DHWD23PURZ made for 24/7 NVR or DVR recording?
   Yes. WD Purple drives are engineered for continuous surveillance workloads and stable multi-stream recording, which makes them a better fit than standard desktop drives.
   
2. Will this 2TB drive work in my recorder?
   It should work in most recorders that accept a 3.5 inch SATA hard drive. Confirm your recorder supports 3.5 inch SATA drives and 2TB capacity per bay, then install and format the drive inside the NVR or DVR.
   
3. What does “supports up to 64 cameras” mean?
   It refers to the drive’s ability to handle multi-stream surveillance workloads typical in larger systems. Real-world results still depend on your recorder settings, camera bitrate, and the number of cameras recording at once.
