DVRT Overview


Digital Video Recorder Transmitters DVRT's

Digital Video Recorders Transmitters allow remote viewing of live and recorded images from anywhere in the world. Analog Video Surveillance Systems were the standard in the past. Todayís technology: PC Based Digital Systems outperform analog and embedded systems in all areas: ease of operation, speed to search for an incident, storage capacity, less failure, image quality, remote capabilities, and data portability. Cascadia offers thirteen (13) different DVRT systems from entry level to advanced. Each system is configured with Intel server technology. (DVRT system's can be built to meet your hard drive specifications.)

The entire Cascadia DVRT Family from the S304T to the SHW48016T were designed to eliminate the guessing game related to Digital Video Recording. All the DVRTís operate on the same software, only the hardware changes, making affordability its greatest asset. This philosophy provides key results: Low Cost, User Friendly Operation, Easy Upgradeability, Maximum Performance, and Reliable Operation.

Digital Video Recording

Digital Video Recording is a process which transforms analog video signals from cameras to compressed small digital files. These small files are saved to the hard drives for fast recording and retrieval. Intelligent Search mode allows instant playback by time date. Event Search is used to search specific events like open doors, rather than having to search though video which was recorded when motion was detected in front of them.

Duplex video multiplexing (simultaneous viewing and recording of up to 32 video input sources) is combined with Motion Detection. When Motion Detection is activated video will only be recorded when there is motion, reducing mindless hours of tapes. This feature also maximizes Hard Drive space.  

Digital Video Transmission and Retrieval

The Cascadia's Digital Video Receiver (DVRT) transmits video to the remote site of your choice and allows you to retrieve (download) recorded video from anywhere in the world. This PC-based transmission system provides convenient remote access to your recorded images. View recorded video from Remote locations (while recording). Remote Viewing delivers the same quality images as the Site is recording. 

Built-in Multiplexer

Each Cascadia's DVRT has a built-in Multiplex/Multiplexer with the capability of recording up to 32 video inputs while performing other functions. Cascadia Systemís Multiplexers can record up to 480 frames per second, shared between multiple Channels. Cascadia Systemís DVRTíS display up to 480 frames per second live, while recording all video channels to the Hard Drive.

Advantages of Cascadia DVRT's

  • Easier to use
  • Records more images per second for extended periods
  • Smaller file size
  • Records Higher Quality Images
  • Advanced Search Features
  • Creates Portable Video (Remotely Accessible)
  • Video Motion Detection (eliminates mindless hours of video)

Various Recording Modes

  • Motion Recording: Records when there is activity
  • Continuous: 24 hr Recording
  • Event: Automatically records when alarm inputs are triggered
  • Audio Recording
  • Voice Activated Recording
  • Pre-Alarm Recording
  • Post-Alarm Recording
  • Dual Mode (Continuous / Motion Detection): Allows recording by specific time

Motion Detection Recording

Motion Detection Recording records only when there is activity in the cameras view. Unlimited motion detection zones can be added to each camera view. When the DVRT detects motion (changes within the image of the motion detection zone) it can alarm the operator.

Recording Duration and Storage

Cascadia System's DVRTíS are designed to record thousands of hours of continuous full frame video. Recording time is only limited by the amount of Hard Drive space. When Hard Drives become full, the oldest data is automatically deleted and the new data is recorded in its place (FIFO), all without any additional management time to maintain the process. The DVRT Family is also available with optional back-up devices, for long term removable storage. Customize your system to meet your needs.

MPEG4 (Motion Pictures Expert Group) Compression

The Cascadia Systems DVRT uses MPEG4 and JPEG compression algorithms to provide the highest quality compressed video. JPEG technology is the most effective method available relating to image size and image quality. MPEG4 and Applied JPEG compression surpasses other compression technology like, MPEG2, H.263 and H.324 and Wavelet compression. The DVRTíS record an average 2-3 k image size and deliver outstanding security quality images when enlarged. Example: A Wavelet 16-24K file equals the same quality as Cascadia's 3K file.

Remote Viewing and Video Transmission

Cascadiaís Applied JPEG technology increases the speed and maintains the quality of the video. The operator can view live remote video and have instant access to all locally archived data any time. Upon alarm, video can be transmitted from the DVRTíS to remote sites via Ethernet, ISDN, PSTN, DSL and TCP/IP to a central station or other monitoring location.

System Control through Remote Access

Cascadiaís DVRTíS fully support remote access and control of all of its functions via ordinary telephone line (PSTN), ISDN, DSL and TCP/IP. Thus, providing a cost-effective solution for any security and surveillance application. Simply install the Remote Software on a any PC (with 1024x768 Display) and you can view any remote site and control any of the DVRT functions or cameras at any time. All settings and configurations of the DVRT can be saved and restored from the remote software.

Compatibility with other Systems

A Analog Video Output allows the NTSC signal from the DVRT to be displayed on any video monitor. The DVRT Microsoft Windows XP user-friendly design allows for easy operation, even by operators who are not familiar with computers.

Simultaneous (Multiplexing) Operations

The Cascadia's DVRT can perform several simultaneous operations: Live Local Viewing, Live Remote Viewing, Recording, Local Playback, Remote Playback, Local System Configuration, Remote Location Configuration and Saves (copies) video to removable storage devices. Advanced digital technology allows uninterrupted operation so you can view yesterdayís recorded video, while recording and viewing todayís live video.

Intelligent Search

The DVRT can search up to 32 channels simultaneously. The intelligent search feature eliminates wasted time, expenses and the inconvenience of manually searching through mindless hours of recorded VCR tapes. The video search is indexed by camera, time, date or event.

PTZ (Pan/Tilt/Zoom) Controls

Controlling PTZ cameras is as easy as clicking a mouse. This PTZ feature allows you to pan/tilt and zoom for a closer look. Even if the operator is at a remote site, the operator of the remote location manipulate the PTZ controls of any camera. Each Camera can be a different Manufacturers P/T/Z.

Password Protection

Passwords restrict the operators access to the programmable features of the DVRT and allow program termination to be controlled only by authorized personnel.

Authentication (Acceptable by all Courts)

All Bitmap files can be watermarked. Call the police and have them save the video to a AVI file on a CD-RW and place it in the evidence bag. This insures the U.S. Court System that all recorded video is in an unaltered format.
