The  E-DVR-402 is a high quality, yet low cost 4ch embedded DVR family. Featuring 4 video input and 4 audio input channels, the unit can record 1 channel at 4CIF (704x576) resolution and 3 channels at CIF resolution (352x288).

Based on an embedded x 86 CPU and Linux RTOS, the E-DVR-402 is ideal for reliable stand-alone recording in all surveillance applications.

MONITORING

Monitoring on all 4 channels is in-real time (25 fps) in multi or single display. 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 a hi-resolution HDMI 1080 monitor output for standard PC monitor connection or a composite video output for Video monitors. Video channels can be displayed full-screen or multi-screen in quad mode. The unit can also be configured to rotate between the different views.

CONTROL

Extremely easy to use and very responsive, the E-DVR-402 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 special keyboard (E-DVR-NKB) is available for remote control of multiple DVRs over TCP/IP, RS485 or RS232. 

RECORDING

Utilising the very latest in H.264 compression technology, this DVR is able to record ch1 at full 4CIF resolution and the balance of the channels at CIF resolution. All video channels are recorded in real-time (25 fps). With the E-DVR-402 you no longer need to worry about low frame rate recording. The recording quality after compression on channel 1 is equivalent to 460 TVL which allows you to record a priority camera at full resolution (i.e your front door).

Recording can be configured to activate via schedule, motion, hardware alarm input or manually. For storage, the E-DVR-402 has capacity for one sata HDD. 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.

BACKUP

Recorded video can be backed-up through the unit's USB port. 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.
