Jerry,

(Re: your last statement:) I don't.  It's good advice, though I guess 
you meant it as an insult.  Thanks for that.


I wasn't claiming 2fps as a maximum rate, only that it was what one 
person used and was happy with, someone who was running a webserver on 
the same RPI which was also running the camera.  I haven't yet seen any 
load averages or throughput numbers mentioned for this and that 
configuration... which would be what we should be talking about.  Not 
having those, but only the case cited, we can consider 2fps a minimum 
and one which likely could be improved upon.


You assert that a higher frame rate is necessary.  I'd say it depends 
upon the environment.  If someone is going to walk through my yard and 
steal or break something or try to break in, 2fps will be fine.  There's

2fps is not considered adequate for security.  Too much can get lost.
The minimum generally recognized is 7.5 fps.  The RPi has trouble with
that, even if a webserver isn't running.  As for offloading the video -
if you do it via the ethernet port (vs. pulling the SD card), you'll
find your RPi won't handle it.  7.5fps at 720p with 24 bit color comes
out to over 20 megabytes/sec. - far beyond the RPi's capabilities.

So, is the solution to go to a lower resolution camera?  Not really.

There are three levels of detail considered for security cameras:

1. Observation - something happened
2. Recognition - something happened and it's someone you recognize
3. Identification - something happened and you don't recognize the
person but can match the person to a picture, lineup, etc.

#1 doesn't help much - other than to maybe tell you the exact time it
happened.  After all, you already KNOW something happened.

#2 works if you know the person - i.e. you can see and recognize your
kid when he/she comes home.  Much better, but it doesn't help much if
you don't know the person.

#3 is required for usable security.  To get this, you need a resolution
of around 5px/cm (12.5px/in) at the face.  Anything less and you will be
*very* lucky to get any useful information.

There are a lot of people who know nothing about what they are doing,
yet think they have security.  But how many of these people have
actually used the information after a crime has been committed?

Additionally, as I said before - the RPi doesn't run Debian - the
processor the RPi uses is ARM V6 - which is old and not supported by
Debian (or any of the standard distributions).  So you are required to
use their version (Raspbian) and the software they supply (unless you
can compile for ARM V6 yourself).

The RPi is a cheap toy, but that's about all it's good for.  The ones I
evaluated are now in the landfill.  There are much better ones out there
for very little more.

You really shouldn't comment on things you know nothing about.

You've never actually tried a RPi with a camera, have you?

As Ken said, the RaspberryPi is a very bad choice for such a job.  The
ethernet port internally is processed by the USB connection.  Throughput
is very limited, and even the lowest resolution camera is likely to
overload it to the point where it crashes or, at a minimum, loses data.

Plus it runs a special version of Debian (Raspbian), which is
incompatible with Debian - and many of the Debian packages are not
available.

Before you recommend something, you should try it.  I have a client who
looked seriously at the RPi before discarding it for another board (I
can't say which, but it wasn't a whole lot more expensive than the RPi -
and it works).

Thanks for the warning, Andrei.  (Whenever  it is I get around to 
putting an RPi with a camera together) I was of course planning first to 
test one unit.  When I read about this project, I didn't come across 
anyone talking about performance issues.  The CPU on the RPi is 700MHz, 
which, while not screaming fast, isn't exactly slow.  I'm sure it would 
be wise, however, to shut down unneeded services and generally trim down 
just to what is necessary.


In addition, my plan was not to save the video to a local drive, but 
rather to send it (over wifi/USBv2... and just when motion was detected) 
to a file server.


What other cheap devices devices were you referring to that would better 
handle the load?


Thanks again.

That is pretty much exactly the configuration I was thinking of 
setting up here.

In this case I have a Trendnet IP camera which will write to an NFS 
share. I was looking for a server device that would be quieter and 
consume less power than a conventional machine that I might be able to 
run in a headless configuration. The Raspberry Pi seems to fit the 
bill.

From what I've read, some have set up such a system on a Raspberry Pi 
running a version of Debian called "Raspbian".  An RPi can be  had in 
the US for $30-40 and a camera which plugs into a dedicated port on the 
card for about $50 (though I haven't checked prices for months).  The 
Raspberry Pi website has How-To's which also discuss motion-detection, 
off-loading of video, and related topics.
