Four-Channel D1 Digital Video Recorder with H.264 Encoding

 

For the small to medium sized video security system, the digital video recorder (DVR) will function as the central controller.  This module is more than a replacement for the VCR. The better quality security DVR is a memory device and a computer.   It can apply logic and integrate the system with the rest of your world via the computer network and Internet.

Xenon is an emerging star in the field of Video Security hardware.  Xenon makes a full line of high-quality security cameras, digital video recorders (DVR), and accessories. 

This is the 4 channel version of their DVR with h.264 encoding, which greatly increases the efficiency of video data storage (h.264 is also used with Blu-Ray DVD).  The specifications for the 8 and 16 channel models are similar to the 4 channel system, but multiplied.  The DVR includes support for either an internal SATA hard drive (max 2 TB) and/or a recordable CD drive.      

The DVR design includes an embedded microprocessor running a uClinux (pronounced “you see linux”) operating system.   The firmware is burned into flash memory, making it more stable and reliable than software programs running from a standard hard disk drive.   Software for managing large installations with multiple DVR systems, called “Centralized Management System” (CMS), up to a total of 200 cameras, is part of the package.  Data can be archived either over the network or over a USB (1.1) port.

 

Technology for Video Security

These systems can playback 4 channels simultaneously, making review of video much more productive.  For example, if we were reviewing video from a hotel, we could synchronize the 4 playback channels to watch a hallway, an elevator exit, the lobby, and finally the parking lot.  In this way we could monitor the travel of an individual through the facility. 

A VGA output for connecting to a local monitor is included.  Many installations will not need a local monitor except during startup and troubleshooting, since most functions can be accessed over a network.  The speed of record and playback (NTSC) is 120 frames per second (FPS) per channel.   The system is compatible with D1 resolution.  

 

Motion Detection Capabilities

The systems are equipped with sophisticated motion detection.  The software allows you to define active sensing regions of the viewing area, and the control of sensitivity.  If, for example, a camera is monitoring a room at a time of day when there should not be any activity, if the camera detects changes in the scene, the DVR can automatically send an email and/or close a relay which could be used to activate an alarm.  Motion detection triggered recording is also possible, greatly increasing the efficiency of the storage in some environments.

The DVR family is fully “web enabled”, allowing you to view the data through Internet Explorer (currently Firefox and Safari browsers are not ActiveX capable, preventing compatibility) or a web enabled mobile device.  The Xenon interface allows control of most of the DVR functions, as opposed to some alternative DVR interfaces, which only allow monitoring of data, often not even allowing backup of data over the network.
