4 Channel DVR Standard Resolution CIF

This Non-PC Based Digital Video Recorder utilizes the most advanced technology in video/audio encoding/decoding, hard disk record and TCP/IP. It has both the features of a digital video/audio recorder (DVR) and digital video/audio server (DVS) . It can work as a stand-alone or be used to build a powerful surveillance network, widely used in banks, telecommunication, transportation, factories, warehouse, irrigation, etc.

The DVR-004S1C digital video recorder is the economy version of the Enterprise Class 2C and 4C series that combines value with a powerful H.264 performance. Like the DVR-004S2C, the DVR-004S4C is an enterprise class digital video recorder utilizing an H.264 hardware compression DSP from Texas Instruments. The DVR-004S1C can push video and audio recording at a CIF resolution on every channel, real time. The versatility of this unit is extensive. Each camera input can be independently configured with variable bit rates, frame rates, record modes, compression, and more. Options with audio recording use the OggVorbis audio standard at a 16 kbps bit rate. The output video and audio streams are integrated to comprise the synchronized H.264 stream. Video and audio coincide with each other from beginning to end. The USB 2.0 port allows video and images to be saved to a USB flash drive, USB external HDD, CD-RW/DVD-RW for simple data transfer. The network software allows for files to be copied to a PC or server. The USB also allows mouse support (mouse included). Remote viewing, playback, configuration, upgrade, reboot, and backup are all standard on the DVR-004S1C. The embedded web server enables users to perform all these remote function via an Internet Explorer web browser, eliminating the need to install software. Client software is also included for central monitoring and alerts for as many as 16+ DVR-004S1C units. Synchronized audio is available through the client software or Internet Explorer


Up to 2 terabytes of storage can be installed in the unit, providing years or recording under proper recording parameters. 3rd generation digital surveillance technology utilizing a proprietary OS, embedded web server, and TI Davinci DSPs bring together the most powerful network-based digital video recorder available.
