Is this drive meant for a desktop PC?

No. It is built for surveillance recorders running 24/7. For a desktop, a standard desktop drive is a better fit.

How is it different from a regular WD Purple?

The Pro version spins at 7200 RPM, has a larger cache and a higher yearly workload rating. Standard Purple drives are slower and rated for lighter use.

How many cameras can it support?

WD rates it for up to 64 single-stream cameras. Real camera count depends on resolution, bitrate and retention settings.

Does it work in a NAS?

It can be installed, but it is tuned for video recording, not NAS file sharing. WD Red drives are the intended choice for NAS.

What is included in the box?

The drive itself. SATA cables and mounting screws are not included, so check what your recorder provides.
