INTRODUCTION

Our new E-NVR-1604 is a hybrid Digital Video Recorder which can record 16 analog video signals and 4 IP digital video streams. It is the ultimate in embedded stand-alone recorders. Based on an embedded processor and Linux RTOS the unit is ultra-stable and ideal for unattended recording applications.

The unit has 16 x real-time (25fps D1) video recording channels and 4 x Megapixel IP digital video streams. Support is provided for compatible VGA or Megapixel format IP cameras. In addition to these it has 16 real-time analog audio channels.

MONITORING

Monitoring on all 20 channels is in-real time (25 fps) in multi or single display with an HDMI monitor output at 1080p resolution. This makes the unit ideal for use in areas with fast moving pedestrian traffic or with PTZ and high speed dome cameras. The DVR has several monitor outputs including 2 x composite video outputs and a choice between VGA and HDMI output for a PC monitor connection. Video channels can be displayed full-screen or multi-screen in quad, nine, sixteen or 20-way mode. The unit can also be configured to rotate between the different views.

CONTROL

Extremely easy to use and very responsive, the E-NVR-1604 has a colourful user-friendly GUI and various methods of user control.

The easiest is via a standard USB mouse. Extremely responsive, all functions can be accessed via the mouse, including setup, playback, PTZ control and monitoring. Alternatively the IR remote control can be used or the front panel controls on the actual DVR. A jog shuttle allows for VCR/DVD-type playback. For control room or remote operation, a special keyboard (E-DVR-NKB) is available. The E-DVR-NKB can be used to control multiple DVRs over TCP/IP, RS485 or RS232.

RECORDING

Utilising the very latest in H.264 compression technology, this DVR utilises hardware compression chips. This allows it to record each video channel in real-time. With the E-NVR-1604 you no longer need to worry about low-res low frame rate recording. The recording quality after compression in the D1 mode is equivalent to 460 TVL which allows you to take advantage of today's hi-resolution cameras. Most typical DVRs record at 240 TVL. IP Video streams are recorded at upto 1920x1080 (1080p) resolution which allows one to capture 1.3Megapixel or 2 Megapixel cameras.

Recording can be configured to activate via schedule, motion, hardware alarm input or manually. For storage, the E-NVR-1604 has capacity for eight SATA HDDs. A 5.25" DVD-drive can be also be installed inside the unit for data backup (in place of one of the HDDs). Operation of the DVR is Quadplex, meaning recording continues during playback, monitoring and network transmission.

PLAYBACK

Cameras are played back individually through the search menu function. Various playback speeds can be selected including x1/4, x1/2, x1, x2, x4, x8 or frame by frame. Video and Audio can also be played back from the unit across a TCP/IP network with the included Client Software or via a Web Browser.

BACKUP

Recorded video can be backed-up through the unit's USB port or to an installed DVD or CD drive. Any individual camera may be backed up for a pre-determined time. The video is then saved in a proprietry file format. This file can be played back on a PC with the playback application installed. With this application, still images can be obtained or the video converted to a standard AVI format. For remote backup over a TCP/IP network, the client software can be used to download individual camera clips.

OTHER FEATURES

One of the many other DVR features includes direct PTZ/speed dome control. This is via the integrated RS485 interface. Several RS485 protocols are supported allow control over a variety of manufacturer's products. Each channel on the DVR can be configured with different brightness/contrast and hue settings. These can also be set for a particular time of the day which is helpful in terms of day/night cameras. Another one of the many features is that of 'hidden cameras' For applications where a covert camera is to be installed, any of the channels can be hidden from the main operator's view. User rights can be configured indivudally with access to certain cameras or all cameras, as well as access rights to playback and or configuration changes.
