The DNR-312L mydlink Network Video Recorder with HDMI Output is a standalone storage device that can record video from up to nine network cameras to its dedicated HDD storage1 without requiring users to turn on their PC. Powered by mydlink technology, the DNR-312L supports real-time remote monitoring and playback via a web browser using the mydlink website or the NVR’s web GUI. The DNR-312L has the ability to continue recording while a user is viewing or searching footage. The DNR-312L’s HDMI display output and playback ability make it a convenient and effective standalone video recorder.

mydlink Technology on your Mobile Device

The DNR-312L enables users to remotely view and manage mydlink enabled devices from anywhere via a web browser using the mydlink website or the NVR’s web interface. With the mobile app, view your DNR-312L from your iOS or Android mobile devices.

Versatile Monitoring

Users are provided with a variety of options for viewing and organizing camera footage onscreen. For a system with multiple channels, users can simply drag and drop selected cameras to the viewing area. Camera name, frame rate, bandwidth and recording status are shown on 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 increasing security. Administrators may also choose access privileges for users by specifying the cameras they may access. The recorded data can also be backed up to additional storage locations.

Extensive Recording Functionality

The DNR-312L’s 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 userdefined 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. With complete video management and the ability to playback and record video simultaneously, the DNR-312L is an extremely convenient and effective video recorder. And the small size and portability of the DNR-312L make it easy to deploy in any location.

Bundled NVR Software

The NVR software bundled with the DNR-312L consists of three main components including a Playback Manager, a Backup System, and an NVR search tool. The Playback Manager includes a 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.
