Does an NVR come with a hard drive?
Most standalone network video recorders (NVRs) don't come with a hard drive, so you have to buy a compatible internal hard disk drive (HDD) separately.
Why NVRs Usually Lack a Hard Drive:
Customized Storage: Manufacturers leave storage size up to you, based on how many cameras you have and how many days of footage you want to save.
Bundles vs. Standalone: While a few complete camera kits or specific bundled packages include a hard drive, standalone NVR units sold online or in stores typically state "HDD Not Included
