GV-800 Series Video Capture Boards
The primary difference between the GV800 and GV600 series of video capture boards is the speed. GV800 series boards have a total display and recording speed of 120 frames per second, allowing viewing and recording speeds of up to 30 frames per second per camera with 4 cameras. When critical applications call for full motion video, this is the product. Software is basically the same as for the GV600 series.
These PCI compatible, add-in video capture boards will process full color 320x240 and 640x480 CCTV camera images at an amazing 120 Frames per Second. The CCTV security cameras can be all color or all B/W or a mixture of both. Local (server) software is Windows 98, Windows ME, Windows 2000 and Windows XP compatible and remote software is Windows 95, 98, ME, 2000, XP and NT compatible. Local and remote versions are provided. The local (server) software can only be run on one system, while the remote software can be run on an unlimited number of systems. The remote software can be run on computers in a Local Area Network (LAN) using TCP/IP protocol and in remote systems dialing in over a direct modem connection, high speed line and/or over the Internet. Recording is accomplished when motion is detected in any camera field (or continuously or at preset times).
 GV-804 up to 4 security camerasGV-808 up to 8 security cameras
GV-816 up to 16 security cameras
Key Features
Each CCTV camera has its own configuration
Video quality, alarm notification, mask areas, motion detection or continuous recording, motion detection sensitivity, compression mode (MPEG4 or wavelet), smart recording, camera name, camera recording speed and brightness/contrast/hue/saturation can be set in the software for each camera.
Video Resolution
Camera images can be displayed and recorded in a choice of 640x480, 640 x 240 or 320x240 pixels. All cameras images must run at the same resolution although this can be changed at any time.
Display
Live video can be displayed in single camera, full screen format or in selectable multi-camera formats. Switch from a multi-screen format to single camera and back, by a single mouse click on the selected camera view.
Motion Detection
When motion is detected in a camera field in an unmasked area, recording commences. Recordings are made in video clips which are date and time stamped in a log file. Log files can be stored locally or remotely over a network. We have found the motion detection sensitivity of the software to be one of the best available.
Mask Function
Areas of camera fields where motion is to be ignored can be user defined (masked), for each camera. Multiple mask areas per camera are permitted. Areas inside a mask can be cleared.
Smart Recording
Smart recording can be selected by camera. This enables the full available recording speed to be allocated only to cameras that are actually recording at any particular time.
Digital Watermarking
Digital watermarking can be selected for recordings. Any recorded video exported from the original hard drive recordings are thus ensured to be unedited. This is a particularly important point when video is to be used as evidence in court.
Recording Playback
The log files of recorded video clips can be sorted and accessed by year/date/time. Video recordings can be played back while current recording is taking place (recording speeds will slow down). Recordings can be zoomed in/out and moved around the viewing area, on playback. Recordings can be played back at normal speeds, higher speeds, slower speeds or frame by frame. Recordings can be played back by individual camera or all cameras at a time. Switching from multi-camera to single-camera playback is as simple as clicking on a particular camera window while playback is operational. Additional editing features are provided for image sharpening, exporting, adjusting brightness/contrast and printing. Video clips can be exported as .avi files, playable in Microsoft media Player or similar. Individual frames can be exported in many file formats, including .jpg's. Exported video clips can have the date, time and camera name stamped on the video in a choice of colors.
Communications
Remote communication is supported by dial-up server, web-cam server, TCP/IP server and multicast server. All can be turned on or off with just one mouse click. Compression of transmitted images can be set from remote systems as MPEG4 or JPEG, independent of recording compression of the host system. MPEG4 will provide much faster transmission. New Webcam software allows up to 16 cameras to be viewed on one screen from the same or multiple DVRs. Remote communications with Win CE equipped PDAs now supported with G-View.
Audio Recording
Up to four audio channels can be recorded with all GV-800 series based security systems. This requires the addition of the GV-Audio connector. Recorded audio can be played back in synch. with single camera video playback. Live audio is not heard.
Alarm Notification
A notification of motion detection and recording can be immediately sent to a remote telephone, pager or computer.
Zoom in/Zoom out
Zoom any one camera in or out by mouse clicks or on playback in single camera or multi-camera playback modes. Camera views zoomed past the limits of the viewing window can be moved around to see any area.
Storage Capacity
As available disk space runs out, the system will overwrite the video clips with the earliest dates. Recording can be specified for any single hard drive or for multiple drives.
