Lenovo EMC px4-300d NVR review

Price when reviewed

The Iomega brand may have gone, but the company lives on as Lenovo EMC; its px4-300d network video recording (NVR) appliance proves there’s life in the business yet. Effectively, it’s Lenovo EMC’s px4-300d NAS appliance with Milestone’s Arcus IP video-surveillance software added.

This means that the NVR version includes all of Lenovo EMC’s standard NAS and IP SAN features, and cloud backup services. The hardware looks up to the job of video recording, too, since it has a 1.8GHz Intel Atom D525 teamed with 2GB of DDR3 memory, and four SATA hot-swap hard disk bays.

We found installation a cinch. Simply fire up the appliance and go straight to the Lenovo EMC setup web portal. This discovers the appliance and whisks you off to the administration web console.

The next step is to add cameras, which the appliance attempts to auto-discover. For testing, we used Axis Q1755, Trendnet TV-IP262PI, and D-Link DCS-6511 and DCS-7513 IP cameras. After a few minutes, they all popped up in the Arcus interface, with each one flagged as requiring attention.

All we needed to do next was enter the appropriate login credentials for each one, after which point they became fully operational. We had less luck with Compro’s latest TN600W PTZ IP camera, however. The appliance wouldn’t discover it, nor talk to it when we added it manually.

When you add a camera, continuous recording to the appliance’s vault is enabled by default, but you can turn this off if you wish. Each camera’s settings page shows how space is being used by the selected camera, and allows all recordings to be deleted with a single click. Frame rates, resolutions and MJPEG, MPEG-4 or H.264 codecs can be set for each camera and, where supported, the image can be flipped vertically or horizontally.
