Technical specifications – NVR4432-EI

Where this NVR fits

Recommended for factories, hospitals, campuses, malls, logistics centres and large apartment or office developments requiring thirty-two IP camera channels, four HDDs and advanced event search.

Hard disks and IP cameras are not included unless a selected package explicitly lists them. Recording days depend on camera count, resolution, frame rate, codec, bitrate, recording schedule and installed surveillance-grade HDD capacity.

Compatibility and ordering guidance

Before ordering, confirm total incoming bandwidth, required live-view layouts, decoding demand, HDD retention, camera-side analytics, alarm I/O and display requirements. A camera may stream at a supported resolution while simultaneous local decoding remains limited by the recorder’s decoding specification.

For third-party cameras, ONVIF commonly provides video access, but audio, motion events, smart illumination and AI metadata can vary by camera model and firmware. For dependable smart-event operation, validate the intended camera-recorder combination before deployment.

Frequently asked questions

Does NVR4432-EI include an HDD?

No. Choose surveillance-grade storage separately according to the required retention period and recording settings.

Can I view it on a phone?

Yes. The DMSS app supports authorised remote live view and playback after the recorder is correctly connected and configured.

Will every smart feature work with any IP camera?

No. Camera-side analytics and event metadata depend on the camera model, protocol and firmware. Confirm the exact combination before purchase.

How should I choose HDD capacity?

Calculate using the number of cameras, bitrates, recording hours per day and retention target. Continuous recording needs considerably more storage than event-only recording.
