Hindsight
What is HindSight?
HindSight is a system for recording and playing back digital
video, but it is more than just a digital VCR! Going digital has
allowed us to add features that analogue VCRs just do not have,
such as automatic indexing and sending video over a computer
network.
HindSight digitises, compresses and stores video onto a hard
disk. HindSight can also log supplementary information such as
data from a card key and store the data synchronised to the
video. HindSight's advanced event and alarm handling features to
allow you to record what you want before, during and after an
alarm condition. HindSight can distribute the stored information
over a local area network and includes powerful tools to convert
captured video into standard PC formats which enable you to use a
standard PC to display and print video frames, and to view video
real-time using a plug-in decompression board.
What Advantages does HindSight Give me?
Pre-trigger capture: HindSight allows you to see what happened
before an alarm condition. HindSight will record live video
continuously to a buffer. If something triggers an alarm, then
the buffer shows what happened before the event and is saved for
you to analyse later. You can configure how much video data you
want to save before and after the event. If no alarm occurs you
can save any proportion of the video in the buffer (like a
timelapse VCR) from none to live video.
Synchronised Data Logging: HindSight allows you to log
information along with the stored video, for example synchronise
the amount rung up on a till with video data, or who operated a
card entry system, or an alarm going off. When you want to view
the video data our powerful display software allows you to go
straight to the point on the recording you want, so you don't
have to watch hours of video where nothing happens. Just select a
time or an event from the log, and go straight to it! If you have
archived the image to tape, the log software can tell you which
tape it is on, wind the tape to the correct place and copy it to
hard disk for fast access and review. Multiple HindSight systems
can be synchronised together or with other systems using a single
timing pulse.
Simple Local Operation: You can operate HindSight like a
video-recorder (Play, Stop, Variable speed FF and RW, Pause,
Single Field Advance, Single Field Back, Reverse Play and PRINT),
either by using a keypad or by closing contacts.
Advanced Local Operation: With the addition of a PC monitor,
keyboard and mouse HindSight can be configured and operated using
easy to use Windows tools. Advanced configurations also can be
loaded from a floppy or remotely.
Remote Operation and Viewing: HindSight can be operated from a
standard PC across a LAN with various security options. You can
even view recorded video on a remote PC whilst continuing to
record!
Video Storage:HindSight is available with a number of storage
options. Recording can continue uninterrupted while you change
removable media! HindSight is currently available with
re-writable cartridges (2.6GBytes per cartridge) and tape storage
will follow soon.
Digital Recording: Digital recording means no loss of picture
quality due to the storage medium and higher reliability. Video
can be duplicated with no loss of quality.
JPEG Compression: JPEG gives you the best compression ratios
whilst allowing real-time compression and allowing each field to
be viewed without reference to other fields. The compression
ratio can be easily changed to give the best trade-off between
image quality and the length of video which can be saved to hard
disk.
Security Features: Password systems to allow remote control
/viewing from certain computers only, at certain times of the day
/ week. Multiple security levels. Proprietary file format makes
data unusable without conversion software, and the conversion
software enforces password protection. Video encryption option
for high security applications. These features help you to keep
control of the data and prevent copies being given to
unauthorised persons such as TV companies!
PC Gateway Tools: Software tools are provided to enable systems
integrators to take advantage of the many options available on
standard PCs. Password protected conversion utilities allow
conversion of video to AVI format which can be used on PCs to
view real-time video (requires hardware compression /
decompression card). Video can be split into individual fields
which can be viewed and printed on any PC running Windows or
Windows95. Events can be used to trigger other programs, for
example an alarm can be used to trigger sending compressed video
over a modem to a remote site. Video can be stored onto various
media, from a few frames on a floppy to many hours on a DAT tape.
Sample configurations are provided for common applications.
Windows Tools Provide: Preview of the effect of compression
ratios. Alarm handling and configuration tools. Remote control of
multiple HindSight capture systems. Viewing of what is being
recorded on remote systems. Database utilities for handling
events and archived data. Linking events to position in video.
Advanced event handling giving timelapse recording rates from 1
field per day to live video (50 fields per second). Templates for
common applications. A command language is provided for producing
sophisticated applications, and 'C' libraries are available for
complete flexibility.
Other Options: Telemetry control of cameras from host PC.
Ruggardised version. Disk options up to 8 GBytes.
Typical Applications
Security: Replacement of Timelapse VCRs, and get to see live
video of what happened two minutes before the alarm went off!
Record the pass number and video everyone who enters a controlled
area. Record the amount that was rung up on a till and
synchronise it with a video record.
Medical: Record a video of what your patient was doing
synchronised with the output from medical equipment.
Industrial: Synchronise video with what your video recognition
system thought it saw! Provide video evidence for feedback in
process control, with synchronised data from instruments. See
what was happening just before that gauge went into the
red!
Others: Any time you want to record video data and synchronise it
to some external event, HindSight offers new opportunities!
