Xenon PH8808AV DVR with H.264 Encoding

 

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. 

The PH8808AV is the 8 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 DVR includes support for internal SATA hard drives (max 2 TB) and/or a recordable CD drive. 

 

Linux DVR (uClinux) for Video Security

The DVR design includes an embedded microprocessor (ARM7) 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), is part of the package.  Data can be archived either over the network or over a USB (1.1) port.

 

The technology behind the DVR video processing is sourced from Techwell, a San Jose, California company that designs highly integrated video processing ICs.   The TW2700 is a RISC architecture microcontroller capable of real-time 4-channel video compression for security applications.  It can compress/decompress 8 full-size video data streams simultaneously.  Two TW2700 modules are used for the 8 channel system.

These systems can playback 8 channels simultaneously, making review of video much more productive.  For example, if we were reviewing video from a hotel, we could synchronize the 8 playback channels to watch several hallways, elevator exits, the lobby, and finally the cameras in the parking lot.  In this way we could monitor the travel of an individual through the facility.  Attempting this job with single job playback could be very tedious.

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.  

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.

 

Internet Compatibility

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.
