Best NAS for security cameras

Top pick

Synology DS925+ four-bay NAS next to a DX525 expansion unit, which is sold separately

The DS925+ appears here with the optional DX525 expansion unit. Drives and the DX525 are sold separately.

Synology DiskStation DS925+

For a four-bay start, DS925+ is the match, and DS1525+ takes over when retention needs more drives.

Why it suits this job

  • A 4-bay chassis holds the storage.
  • Its best documented network connection runs at 2.5 Gbps.
The catch
No integrated media engine on the CPU means no hardware transcoding.
Go with Synology DiskStation DS1525+ if
your key requirement is storing camera recordings
More reasons we picked it
  • There is no documentation of hardware Plex transcoding on this model.
  • Recording from cameras is supported, with the licensed channel count depending on which software and plan are selected.

Check these before you buy

  • Largest drive it can support
  • Network port and a way to upgrade
  • Camera or Plex software it supports
  • Where memory and expansion top out

What this page can’t tell you

  • Which drives work today may change later.
  • Real transfer speed is only as good as the full network and drive array allow.
  • Plex behavior hinges on the exact media format and client.
