surveillance for PC
Cheers Kevin / David,
Kevin,
As
you say I wasn't able to find much info on the GeoVision web site - or
anywhere else on the web for that matter!
What
sort of fps would you recommend to get a half decent picture
quality?
Bear
in mind that most of the time there will be no movement on any camera until
say someone approaches the front door or a car drives up to the
garage.
Is
it possible to dynamically set the fps between the cameras? i.e. if I have
25
fps available (GV-600) can I set set 4 cameras with a default of
6
fps then if movement is detected by the software in one camera it
automatically switches that one to say 15 fps and the other 3 down to 3 fps
-
that would be nifty... (do I need as much as 15 fps, or
more?)
The
GV-750 looks like a better option but with 75 fps but is £150 more for the
4
camera option - do you think this would be worth it?
David,
Price wise the Trust 814 looks like a cheep alternative with many of
the features of the GeoVision for a fraction of the
price.
It
may be a bit limited with what looks like only 20 fps available (although
this
is only slightly lower than the GV-600).
It
may be a good way to dip my toe in the water but I'll have to wait for
the new board to come out as I'm running Win2K.
Is
this something you have used yourself? - I haven't been able to find
a
review of the existing 804 board anywhere to find out what it's really
like.
All
I need to do now is figure out how to get the input from 4 wireless cameras
at
the same time - looks like I may need 4 receivers tuned to different
frequencies.
The
cost of this would be significantly more than 4 hard wired cameras but
I'm banned from drilling any more holes in walls as the ball and chain is
afraid the house may fall down. :o)
As a
cheaper alternative does anyone have multiple wireless cameras transmitting
to a single receiver and therefore only needing a video capture card
with
one input?
If
remotely viewing over the web is it then possible to dynamically control
which
camera to view from the client end?
No
doubt I'll think of a few more questions for you all
tomorrow..!
Thanx.
Anto.
Hello Anthony,
Yes - I use this card - I was at
one
stage going to write up a review for Mark's site but what with moving etc.
it got delayed.
Overall I have been very impressed with the
card (I have an 8 camera version) although less so with the support from
Henrys Radio (the UK reseller) or the manufacturer. Henry's also blame a
lot
of the issues on a non supportive manufacturer. These support issues have
been nothing major - more feature issues.
There is now a new version of the card that
supports an audio channel as well. The software supplied is excellent and
extensive allowing full motion detection and remote monitoring and alarm
signalling. It will allow all cameras to be visible on screen and will
record from 'triggered' sources so it seems to suit what you need. Check
the
frame rate is adequate for your needs though, they do do a far more
expensive card with a better frame capture rate.
My gripes have been around the 'closed'
nature of the software and also the hardware trigger expansion card which
is
ridiculously expensive (more than the card itself) - so you can't
reasonably add PIR triggering to the system or use any HA software to force
a capture event. Also as you mention it the pan and tilt integration in the
software requires this expansion option which doubles your cost and
the
implementation is non standard in terms of most UK camera mechanisms and
doesn't support the Xcams which have a bespoke/budget pan and tilt
mechanism.
Any specific questions just ask

Hi,
I want
to set up 3 or 4 cameras around the house.
(2 or 3 outside, 1
inside)
I can't really run cables so wireless would be the best
bet.
(Walls in the way and PC may move to another room at some
stage.)
I want to be able to capture and display all the cams at the
same time
on my PC and view them over the internet.
I have been
looking at the GeoVision GV-600
http://www.geovision.net/e/products.htm
available from
http://www.sicherheitsteam.de/shop/endkunde_int/docs/start.htm
for 450
euros.
Anyone used this card or can recommend another
card for the PC?
Also, would it be possible to connect 4 Xcam2's to
this system to get 4
live pictures simultaneously, or is there a better
solution?
Ideally I would like to be able to view the output on my
TV as well and
have remote / PC / PIR controlled pan and tilt on one or
two cams but
this may be asking / costing too much!
Anyone got a
similar set up??
Anto.
