Video Recorder - Turn Record on/off
Archiver
Posts: 46,084
Hi Folks,
I've got a home security project and I need your help. I want to make a
video recorder start and stop recording remotely. I've got a stamp which
collects info from various sources. I want to keep the unit on record all
the time but on pause. When the stamp identifies someing to record I want to
take the pause off. After a few seconds it will then turn the unit back to
pause.
I suppose I could make the stamp "learn" the pwm from an infra-red control
unit, but I prefer a wired connection. Is there something simple I can do
without buying a special recorder or breaking open my domestic recorder -
can I use the scart connections somehow?
Thanks
Tony

I've been looking at units that "fake" the video remote controll - so I
could use the stamp in the same way. I just prefer a wired connection as I
can be *certain* that the video unit is recording....Otherwise I'll end up
recording all the adverts (!)
Thanks,
Tony

5 minutes) it desengages the pause AND recording mechanism in order to preserve

It is my experience that any video tape recording
device will not remain in PAUSE mode for any length of
time, due to the fact that the heads overheat, and the
system shuts down. Every VCR or Camcorder I have ever
owned does this...
You would need to initiate record mode and stop
instead. But remember, some units even power down
after extended periods of no activity.

I think I just didn't explain properly - yes I understand about the pause
business and the recorder stopping if held for a while in record mode etc
etc.
The underlying control problem is still there however. I take it from the
lack of replies on this basic control issue is that there is no easy way of
controlling this type of function apart from emulating the remote control
unit??? I did wonder if the scart connector has some kind of control wire.
But I could only find one-word descriptions of each wire in the scart
control spec - a bit opaque to me.
Thanks,
Tony

There are some SONY proprietary control called LANC or Control L used in
semiprofessional VCR´s that have this
function.

will eventually wear the tape so bad it won't record.

sub-mini receptacle on them for a pause control. A simple normally-open
switch would start / stop the recording.

I believe, although I may be alone here, that the stamp is capable of
generating the codes necessary to do the job you need. I have tried but
I can't seem to figure out what the IR codes are in a pure sense of the
term. I have an old scope that's only good for a 100 MHz or so, but
fast enough to see the signals from an IR remote. The signals are
generated once when a button is pressed and then a maintenance signal
follows. If I had a good storage scope or one of the scope devices to
put on a parallel port, I think this could be made to work. The stamp
is capable of putting out pulses in the microsecond range and these IR
devices are in the Milli second range. Just my $0.02.

or movie capability and record the digital
files directly to your PC. Except for the hard disk you would basically have
no moving parts.
A number of the software packages have some sort of control or batch
capability that should work for remote control.
Other software packages actually can detect movement and record accordingly.
If your doing something like time lapse photography then you shouldn't have
any problems controlling a digital camera of some sort.
In the worse case you could use a Stamp to send commands to the keyboard
port and trick the PC into starting and stopping and saving out the file by
sending the appropriate keyboard commands to the PC. They've discussed that
at length here in the past too.

SCART connector does not implement recording or pause functions. Do a web
search and you will find may references.
There are some SONY proprietary control called LANC or Control L used in
semiprofessional VCR´s that have this

Well, after that I can't help you, since my knowledge
of IR control systems is limited. Good luck.

Years ago, I made a little "wired remote control" for my video recorder.
I mounted a 7-pin DIN socket at the back side. I connected this socket to
necessary points of the front keyboard of the recorder.
The remote control is a simple set of pushbutons. The only trick I had do to
to was to put a resistor (1K or so) between each wire and the ground, inside
to remote box, to avoid strange behaviour of the recorder.
In your case, you need to simulate a push on the "REC" button (if it's a
one-key command). You could do it with a little relay attached inside your
recorder, and energized by the Stamp (via a transistor eventually). And of
course, the same applies for the "STOP" button...
Hope this helps.
Phil.
