Section 1 - Product Overview
Introduction
The DNR-4020-16P is a standalone wired Network Video Recorder (NVR) which supports multi-channel network cameras with
H.265 and H.264 recording and two SATA hard disks for backup. Thanks to a powerful embedded system, the NVR can record
video from network cameras located in local or remote sites into a dedicated HDD storage without having to turn on a PC.The
DNR-4020-16P NVR supports real-time monitoring and playback from everywhere via browser, HDMI or VGA port. The triplex
function enables the device to continue recording while allowing the user to watch the live view and search for playback videos.
Automated Surveillance
Users are provided with a variety of options for viewing live streams and camera footage on-screen as well as automatically
recording events as they happen, with or without an operator on-site. Event-based recording is available for cameras with
motion detection and Alarm In connections are supported for triggers such as door and window sensors for automated
recording during unusual events. User-defined scheduled recording and continuous recording with automatic overwriting
options help to ensure the surveillance system is running reliably, even when no one is around.
Extensive Monitoring and Recording Features
The DNR-4020-16P’s intuitive interface allows for easy configuration of many functions, including compression, resolution, and
frame rate. Support for multiple encoding formats provides administrators the flexibility to prioritize storage space and video
quality. Featuring live viewing of multiple channels, users can simply drag and drop selected cameras to the viewing area.
Smooth Streaming from Anywhere
The DNR-4020-16P also enables users to remotely view and manage the NVR from anywhere via a web browser. The Gigabit
Ethernet port provides superior bandwidth for viewing 16 camera streams simultaneously, so critical moments can be monitored
and captured at all times. Rounding out the features is the JustConnect+ mobile app that lets administrators easily and remotely
access and monitor the DNR-4020-16P on a mobile device — making the JustConnect H.265 PoE Network Video Recorder a
complete, easy-to-use enterprise surveillance solution.
