Description
The DX4104 Series digital video recorder (DVR) is designed for the entry-level market. The unit provides one to four camera inputs, powerful
video storage management with efficient H.264 compression, multi-event recording, a quick and easy-to-use common user interface, greater
internal storage (up to 2 TB), and network connectivity for up to 100 units. The DX4104 replaces the t raditional VCR and multiplexer combination
and can be used in stand-alone or networked installations.
The DX4104 is easily operated and configured using the mouse, remote control, or front panel. User-configurable disk partitioning is used to
allocate specific hard disk space for storing normal (continuous) and event-initiated video data. The retention time can be different for normal
and event-initiated recorded video. All recorded video is compressed and stored using the latest H.264 compre ssion technology.
The DVR supports single-event and multi-event (a combination of normal, alarm, and motion) recording. You can immediately start and stop
recording through the instant record feature. Each camera can be configured to record at a resolution, qu ality, and image rate specific to each
event. By default, the DX4104 is configured for automated multi-event recording.
For surveillance applications requiring pan/tilt/zoom (PTZ) capability, the DX4104 addresses and controls PTZ equipment such as Spectra®
domes, mini domes, or third-party cameras. The unit operates Pelco and third-party PTZ cameras that support Pelco D and Pelco P protocols.
Video critical to investigation and archiving can be exported from the DX4104 server to USB memory or optional CD/DVD±RW media. Use the
exported video preview feature to verify the video content and quality.
The DX4104 remote client can be used to remotely operate and administer the unit. The remote client includes an export viewer, Web client, and
emergency agent application. You can play back exported video using the export viewer or a Microsoft® Windows®-based media player
application.
The DX4104 remote client is Vista-compliant. At the remote client, users can easily and quickly capture a video scene, save it in JPEG format, and
then store it on the hard drive. Additionally, the remote client can be used to preview and search backed up video. The DX4104 remote client also
allows live viewing and video playback from up to 16 DX4104 units simultaneously. The remote client can connect to as many as 100 DX4104
units.

REMOTE CLIENT SOFTWARE APPLICATIONS

DX4104 supports four software applications that run on a personal computer (PC):
•Remote Client software application: Allows you to log on to, operate, and administer up to 16 DX4104 units. The DX4104 supports a
total of five simultaneous connections when using the client and Web client applications. For more information abou t the remote client
software application, refer to the DX4104 Client Operation/Configuration manual.
•Export Viewer: Allows you to view exported video. It is designed to recognize and verify the digital watermark that is e mbedded in the
Pelco-engineered *.exp video format for DX4104.
•Emergency Agent: Works with networked DX4104 unit s to alert users when one or more channels detect an alarm, motion, or video loss
event. The emergency agent runs on a networked client PC.
•Web Client: Allows you to view live video and op erate PTZ features of cameras attached to a DX4104.
