getting Pd off with motion detecing IP cams sending 100s of emails of
moving bushes and sunshine/shade changes.

One of the IP cams has 2 channels for I/O - so I'm pondering how to send a
signal to it to take a snap when something goes across the cam;s field of
view.

PIR would be perfect but a very narrow "beam" is required to make sure I
get the subject in the centre of the frame... and the IP cam is not going
to be happy with 240v up its I/O - so ???

low voltage PIR? what from where?

a normal 240v PIR and some sort of a relay?

something else?

Use a std 15m quad pir with a pet lens (preferably as narrows vertical
field) then use masking tabs supplied to refine horizontal.
A std pir will be ok but quads are nearly as cheep and more reliable against
false alarming .

Yeah, decent software that allows you to specify a subset of the
camera view to monitor for movement and is smart enough to
not be triggered by sunshine/shade changes due to small clouds
passing the sun etc.

Some 240v PIRs operate relays rather than being solid state. Wether
the relay contacts are "volt free" is another matter...

On both adjust the area "seen" by the PIR with bits of sticky tape.

Much more elegant than farting around with a separate PIR with sticky tape

One of the IP cams has 2 channels for I/O - so I'm pondering how to
send a signal to it to take a snap when something goes across the
cam;s field of view.

PIR would be perfect but a very narrow "beam" is required to make
sure I get the subject in the centre of the frame... and the IP cam
is not going to be happy with 240v up its I/O - so ???

low voltage PIR? what from where?

a normal 240v PIR and some sort of a relay?

something else?

Zoneminder has very closely programmable Zones, to let you define
where you want something to trigger the alarm, and recording.
http://www.zoneminder.com/
No PIR, just the camera feed.
If this is way off track, apologies.

ZM also needs a PC running 24/7..

No big deal when that can be a dirt cheap obsolete laptop.

and is a ****ty bodgey backwards step

And farting around with a separate PIR and sticking tape aint ?

Yeah, right.

You're so stupid you cant even manage to pick a decent IP
camera that allows you to specify a subset of the image to
monitor for movement

ALL my IP cams have this feature you think is so "rare"

You can wipe that egg off your silly little face now.

and one that's been designed toi
handle sunshine/shade changes.

and your "well" (if at all) researched IP camera recommendations would
be......?

There are IP cameras with built in PIR detectors.
They don't work through glass.

point taken - i want an outside pir ;)
isn't there just some relay i can bung across a pirs switched output
(where the floodlight would usually go) and close the ip cams i/o circuit?
either momentarily or for the duration of how the pir is setup?
don't know just yet how the cam "wants it" but t'will be one or t'other

Some 240v PIRs operate relays rather than being solid state. Wether
the relay contacts are "volt free" is another matter...

precisement - which "some" are those though?

Something like:

http://www.screwfix.com/p/140-standalone-pir/11291

Is certainly relay based. One side is wired to mains live to provide a
switched mains output as its "normal" output. However isolating that
should not be too difficult. (I can't remember if its wired literally,
or if you would need to cut a PCB trace)

thanks john , out of curiosity - how do you know?

I have a couple fitted here. They click when they activate ;-)

i'll happily acquire one and delve in with me meter, standby..... ;)


For reliable "person" detection, then using a pair with some external
logic to detect sequence triggers rather than simple single triggers
is a way that many intruder alarms minimize false triggers.

would such logic be available for an electro numpty like me to buy
reasonably pricedly?

Should doable if you don't mind knocking up something on a bit of
veroboard. (obviously posh ardunio type solutions would also work - but
probably overkill)!

In fact, you could probably use one with no modification, but use its
live out to provide the live in to the relay on the second one. Then use
its live out to drive an external relay to give you your no volt
contacts for your trigger. That would take advantage of the timer
mechanism built into them to reset your trigger as well. So the first
would act as an "activation trigger" - it goes live - set to hold on for
the shortest delay available (few secs), that then enables the output
from the second one

If you think the break beam detector would be reliable, then maplin have
a small kit for under a tenner. (you would probably want to knobble the
buzzer on it though!)

Using some decent software on the image from the IP camera
makes a hell of a lot more sense than farting around with a
separate PIR and sticky tape, ****wit.

I use this with my IP cameras:
http://www.pysoft.com/ActiveWebCamMainpage.htm

It runs on a low spec Atom based PC, and can be configured to email /
ftp video or photos as required when it detects movement in the areas
you specify.

mmm intellisting - can you point me to a suitable relay plse?

Also in practical terms how would the 2 PIRs be "aimed" etc to achieve the
reduction in false positives as compared to say a single PIR?

each PIR pointing across the target zone with a gap between? if so how
would that catch persons moving in both L-R and R-L directions?? (i.e. if
PIR 2's function relied on PIR 1 being triggered first, then wouldn;t that
only work "one way"?)

I imagined taping up a lone PIR's detector lens (by trial & error) such
that a vertical "slit" of detection zone was left to trigger the IP cam to
take a snap whilst the subject was mid-frame in the cam's field of view....

mmm intellisting - can you point me to a suitable relay plse?

Any relay with a 230V coil will do, say:

http://cpc.farnell.com/omron-industr...vac/dp/SW03490

(Has more switched poles than you need)

http://www.maplin.co.uk/5a-miniature-relay-37515

is cheaper, see item N13AW

Also in practical terms how would the 2 PIRs be "aimed" etc to achieve
the reduction in false positives as compared to say a single PIR?

Well that rather depends on the circumstances... if for example you were
attempting to track people walking through a zone, then you may want a
pre-trigger on entry to the zone, and then the secondary in the middle
of it.

each PIR pointing across the target zone with a gap between? if so how
would that catch persons moving in both L-R and R-L directions?? (i.e.
if PIR 2's function relied on PIR 1 being triggered first, then wouldn;t
that only work "one way"?)

Yes, with two like that - it would be one way. You could use more PIRs,
or perhaps have the two on different axis. So you need both to see the
same target but against different backgrounds.

I imagined taping up a lone PIR's detector lens (by trial & error) such
that a vertical "slit" of detection zone was left to trigger the IP cam
to take a snap whilst the subject was mid-frame in the cam's field of
view....

It may well work in practice, although you might find under certain
conditions (foliage waving in the wind etc) that you get false triggers.
That is why beam break detection can be more reliable since it needs
something to obscure the line of sight between source and receiver.

Sorry, should have also said, that you may be able to isolate the mains
feed to the contact side of the relay in both PIRs and then use them in
series as your no volt contacts - i.e. only triggering when both are "lit"

Yes, with two like that - it would be one way. You could use more PIRs,

Or the first one covers the whole area and the second has the narrow
band.
