Before you buy

What to check

  • Check bitrate, channel count, storage size, export, and power budget.
  • Test exports and measure actual recording use before you set retention.

Terms to confirm

PoE supplies power over Ethernet. An NVR records network video.

Ask the vendor to confirm each term for your exact setup.

Prices are listed in USD with read dates. Prices and stock change. Tax, shipping, and setup are not included.

Buying tips

Test exports and measure actual recording use before you set retention.

Storage and retention

Retention days = usable bytes × 8 ÷ (camera count × average bitrate in bits per second × 86,400).

For different bitrates, use their sum instead of camera count × bitrate.

Allow space for formatting, audio, overhead, and storage reserves. Measure actual recording use.

Drive size alone does not confirm the required retention period.
