mydlink™ Network Video Recorder with HDMI



DNR 312L

The DNR-312L mydlink™ Network Video Recorder with HDMI is a dedicated standalone device that can simultaneously record videos from up to 9 D-Link network cameras in 1080p full HD resolution to its dedicated HDD storage1. With the integrated HDMI audio/video output, users can view, control and configure the DNR-312L without the need to turn on their PC.

mydlink™ Technology on your Mobile Device

The DNR-312L is mydlink™-enabled, meaning you can easily set up and remotely monitor from anywhere via the Internet using the free mydlink™ View-NVR app for your smartphone or tablet, or through the secure mydlink™ web portal. Furthermore, you can remotely playback recorded videos as well as control PTZ cameras, allowing you to keep an eye on your home or office anytime and anywhere.

Versatile Monitoring

Users are provided with a variety of options for viewing and organising camera footage on-screen. For a system with multiple channels, users can simply drag and drop selected cameras to the viewing area. Camera names and recording statuses are displayed via the on-screen display. A single camera may be viewed full-screen with two-way audio support. Users can control pan/tilt/zoom (PTZ) functions from within the interface or by directly clicking on the video.

Secure Storage

Administrators may filter external connections to the NVR by IP address, limiting access and thus increasing security. Administrators may also choose access privileges for users by specifying the cameras they are allowed to access. The recorded data can be backed up to additional storage locations periodically or whenever needed.

Extensive Recording Functionality

The DNR-312L’s clear interface allows for easy configuration including compression, resolution, and frame rate for all connected cameras. Once the cameras have been set up, recordings can be made continuously, or according to a user-defined schedule. The NVR also provides event recording based on specific triggers such as when motion is detected.

Convenient and Reliable

The DNR-312L can manage multiple network cameras, providing direct access to view live video and play recorded data over the Internet from anywhere, anytime. Complete video management and the ability to playback and record new video simultaneously means the DNR-312L is an extremely convenient and effective video recorder. Moreover, the small size and portability of the DNR-312L make it easy to deploy in any location.

Bundled NVR Software

The integrated NVR software consists of five main components including a Playback Manager, a Backup System, and a versatile search tool. The Playback Manager includes a clean and simple web GUI interface that allows users to play, search or export video. The Backup System is a flexible backup utility that greatly simplifies the process of backing up video data from the NVR to external storage.
