Wachit connects to a video camera, any home VCR and optionally an
electronic security system. |
|
Wachit detects a moving object in the video signal received from the video
camera. |
|
The sensitivity of the Wachit to detect moving objects is adjustable. |
|
Wachit learns the infra-red signals of remote controller units of most VCRs and
can control them by sending the same signals. |
|
Wachit transforms an ordinary VCR into a powerful and inexpensive security
video event recorder.
|
|
No need for a motion sensor and extra wiring. Wachit analyses the video signal
and detects activity in the scene.
|
|
In many situations Wachit overcomes the need for an expensive Time Lapse VCR.
Unlike systems using time lapse VCRs, Wachit prevents recording of static
images with long duration of inactivity.
|
|
Wachit can be used on tapes that have been recorded by time lapse VCRs to
extract only those parts of a video tape that contain movement. This will save
a long time looking for events within hours of static images recorded by time
lapse VCRs.
|
|
Wachit can be armed and disarmed by an electronic security system. It can also
send a relay contact signal to a security system when a motion is detected or
video signal is lost.
|
|
Installation is very easy. Just 4 push fit connections that can not be
installed incorrectly. Follow a very simple procedure to teach the remote
control codes of the VCR to the Wachit and connect a security camera to the
"Video In" of Wachit. When a motion is detected Wachit activates the VCR into
record mode. When there is no activity, it stops the VCR. No more static video
with no image activity.

We are currently looking for dealers
and distributors worldwide to market the Wachit product. Please

Frequently Asked Questions:
|
| Q |
Does the Wachit require a camera with a PIR built in? |
| A |
The Wachit range of video motion detector equipment does not require a PIR
sensor. Instead, the VMD-19 microprocessor analyses the incoming video signal
for motion frame-by-frame. The Wachit VMD-19M works with any camera that is
connected to a VCR. This reduces the need for PIR wiring, eliminates the issue
of limited PIR sensing range and allows the recording of non-thermal movement.
|
| Q |
How does Wachit detect movement through the camera? |
| A |
The video camera signal is sent down a video cable to the Wachit VMD-19M,
en-route to the VCR. The Wachit is based on the patent pending Farco VMD-19IR
integrated circuit. This integrated circuit both controls the Wachit, and
analyses the video signal frame by frame. The VMD-19 IC module will detect
movement from the video signal (depending upon the sensitivity setting).
|
| Q |
How does the Wachit control my VCR? |
| A |
The Wachit learns your VCR remote control codes and remembers them even when
disconnected from the power supply. Once movement is detected on the video
signal, the Wachit VMD-19M transmits the learnt infra-red remote control
signals to your domestic VCR.
|
| Q |
Most VCR's take a few seconds to actually start recording, in a
situation where recording needs to begin immediately to capture the subject(s),
action, etc... on-screen, how does the Wachit accomplish this? |
| A |
There is a new Quick Response feature of the Wachit VMD-19M that can keep the
VCR in paused state, allowing the VCR to respond more quickly to motion. The
Wachit VMD-19M advances the tape by a couple of seconds every 2-3 minutes to
protect the tape from excessive wear. The end user can enable this feature by
setting a jumper inside the Wachit. The Quick Response feature places greater
demand on the VCR, and may result in accelerated wear and tear. The Quick
Response feature requires that the VCR be paused AND un-paused using the pause
command (as with most VCR's). However, VCR's that require a record command to
continue recording from paused state may not allow this bonus feature. |
